The HUGE 5.9km Scale Model Solar System! 

Yes, and such superluminal speeds result in those touring the model returning younger than when they started.

The speed of light in this model is 30cm per second, which is 1.08km/h, or 0.67mph

It turns out the speed of light in the model is almost exactly 1 feet per second. You can march there and pretend to be light.

​@@nitsanbh this also implies you could circunvent earth in ~4 years by just walking (considering a flat terrain, no oceans and no rest either).

These comments blew my mind. Never thought about the speed of light being "so slow". What a great new perspective, for me that is. Thanks guys!

And yet so weak we can stand upright, walk, run, and jump even though we are basically bolted onto a rock orders of magnitude bigger than ourselves

Soz I accidentally disliked but now I liked your comment

@@CannonRushed But just try and leave !!

And it doesn't rip our moon out of its orbit and we're 41X closer to the Sun.. that is amazing or a lie hahaha

Yep, basically they think we are that dumb to believe this to be true.

If the Earth's circumference had been twice as large, we could have put Sirius next to the Sun in this model in stead of Proxima Centauri.

That was just genous.

Could have included Alpha and Beta Centauri as well...Alpha, not Proxima, is the principle star of that system... and those stars are known to have planets as well. The distance from Alpha to Proxima is about 430 times the radius of Neptune's orbit. Following the Australian coast, that would put Alpha at Brisbane...

@@erictrumpler9652 It's Alpha Centauri A and B. A is slightly larger and brighter than the Sun while B is somewhat smaller and fainter. A is of spectral class G (same as the Sun) while B is of spectral class K (somewhat cooler than the Sun), but they are both considered to be pretty sunlike. Beta Centauri is a giant bluish star (spectral class B) that is much brighter and hotter than Alpha Centauri A and B, but it's also nearly 100 times farther away.

@@fromnorway643 Ok, thanks for the correction... I didn't realize that Alpha B and Beta Centauri are different stars. I thought Alpha B would designate its second planet...

Might be cause it is more science and maybe even educative than art. Public art still sucks.

i won't doubt if 100 out of 100 people believe that, thats the actual distance between sun n proxima centauri beside being known about all planets distances in scale... lol, people usually don't have that much brain cells to comprehend that simplicity or maybe its a place where people leave their thinking power at home..😅☺

@@johnwon6986 Rich to talk about the intelligence of others when you can't write coherently.

Lol

@@XXXX-yc6wv English not my first language n still learning,.. n i m talking about common sense of measuring things, genius..😀

my mind was blown when he said you have to do the entire globe tour to get to proxima 😮

Yes, that was really cool. Also, to think how massive the scale actually is compared to what we see on the books. Would love to visit this place once.

Me too what a great idea.

I live in Melbourne so I did the trail myself. So you see Earth to the moon, the furthest any human is ever been and its 30cms apart. You can touch both at the same time. And I think I rented a bike to do the full distance of the model. Well just our solar system anyway. But actually getting on a bike and doing the distance on a nice sunny afternoon really helps you grok how far it is to Pluto in a visceral way. And then Proxima Centauri, right around the freaking earth. Really puts in perspective how hard interstellar travel is.

Because Pluto being kicked out of the planet club was done by a handful of mean girls who didn’t advertise the meeting where the vote was had. Pluto is a bully victim.

Should have included Charon, since it's more a dual-dwarf planet system, but Charon would be a pin head.

It's the biggest model in the world.

​@@Grodstarknah, I have an incredibly detailed 1:1 model of the solar system. I keep it out in space. In fact, were living on one of the models right now. You can't prove I don't or that we aren't.

I did not know that. Cool!

Also has the chock horizon, where the thermal pressure from the sun is coubtered by the cosmic preasure.

​@@herrantonYou don't own the planets lier

If you traveled to Neptune in four hours, you would become pure energy.

But can you start at the Sun modelo in Melbourne, walk the circunference of the Earth, return to Melbourne and reach the Proxima Centauri model in 4.5 years? If so, congratulations: you're still faster in relation to the scale, than light in the real thing

You would if you yourself were on scale. Good luck with that!

@alphamorion4314 yeah another good route to consider! Even Magellan's crew would have outpaced the scaled speed handily while running that route

You peeps left yourselves out of the equation. It seems this "small detail" escaped your tiny brains (you know, the brains that are one billionth of their real size).

I came looking for this from the Metric World. Thank you!

They put Earth before Venus

@@wintaaaaano they didn’t.

@@thosearentpillows5638 5:48 they did

yeah, for imperial users it might be hard to understand. 10mm=1cm 10cm=1dm (rarely used, most people use 100cm= 1m), 10 dm is 1m, 1000m is 1km, then it's always 000 to go higher so that jump is little bit counter-intuitive

I mean between m and km is also da and h, 10m=1da and 10da=1h, 10h=1km but I have never heard of using deca and hecto while describing distance, diameter, volume, surface area etc. Also there are lower units than mm but you rarely use them, instead you use scientific notation

​@@0NeeN0 "...rarely use them..." Generally quite true. Well put. Yet when you're shopping for the lightest-weight smartphone yet, you may well thank the skilled chip designers who've learned how to fabricate their art on the nanometre and picometre scale. (Which also require smaller and smaller batteries.) This makes a human hair cross-section look almost as big as Jupiter, it does...

​@@0NeeN0 Whst are da and h? I thought 1h denotes 1 hour.

@@MR-intel I made huge errors, 10dm=1dam (10m), 10dam=1hm (100m) 10hm=1km but we don't use those except dm sometimes, because dm cubed is 1l. We use just cm, sometimes decimeters (1=10cm). meters and km (1km= 1000m), nobody uses dm, dam and hm, at least no one I and my friends knew our entire years + teachers (I'm 23)

How far is Sedna compared to Pluto?

It all became much easier for me to understand when I realized gravity isn't just the force holding Pluto onto the sun 6 billion km away, but rather it's the force between every atom in the the universe pulling on every other atom in the universe, and the strength of that interaction decreases with distance. Some areas of space have a higher concentration of atoms and some areas have less concentration. Dense concentrations become stars and planets, and less dense areas become the "space" between "everything else, or normal objects". Then it sort of makes more sense to why each planet keeps going around the Sun in orbits, because there's virtually no other clumps of atoms anywhere else for them to interact with for trillions of miles in any direction. That's why Pluto, only 2,000 km across keeps orbiting the sun that's 9,000,000,000,000 km away! Amazing stuff. This helped me to understand that our moon IS pulled towards the Sun by gravity, it is also pulled towards Mercury, Venus, Earth, all objects in the asteroid belt, and all the way down to Pluto. However, it's SO much closer to Earth than any of those other objects that the earth's gravity pull is _stronger_ than ALL those other forces combined, so that's where the Moon stays. It orbits Earth while always being pulled in every other direction at the same time, just not strong enough to pull it out of orbit (in the near future). The Moon is moving away from us very very slowly, and will eventually cease to orbit our planet entirely. Any "stable orbit" is only ever stable in the relative sense. Eventually all orbits collapse or escape if you run the clock long enough...it's one of the beautiful dances of the Cosmos. It also means, that from a mathematical point of view, that me and you standing on the Earth are adding to the atoms that make the Earth...in a sense we _are_ part of the planet when you consider the gravitational pull of all the atoms in this specific area of space as it interacts with every other atom that _isn't_ part of the Earth.

Now look at our solar system to the galactic center.

Electromagnetism is very strong, but only over very short distances. Gravity is very weak, but over insanely long distances.

@@steffenfrost995 Wikipedia has you covered, not surprisingly. Search for "Solar system model". Probably not a complete list though, there are bound to be more no one has bothered to include. There is one just like this in my home city of Helsinki which I've often biked around. It is built around a large bay of mostly open water, and thus the sun, located on a pole on a hill, is visible from nearly all of the planet sites.

we have one in York, UK@@johanvangelderen6715

Ok

It doesn't take much for a temporary one. You can make your own with a playground ball, roughly 8in or 20 cm in diameter, for the Sun. Then you need some pinheads, 2 peppercorns, and some various nuts for the planets and moons. I used the model below a few times for homeschool and public school presentations. The planet walk is 1,019 yards or roughly 0.6 miles or almost a kilometer long (0.93) and includes Pluto. Dropping Pluto saves 242 yards (221m). So the Sun and the planets are still visible and the model is short enough for an easy walk, even for young children. It doesn't take much extra work to figure out how far the moons are from the various planets, ie the Moon is 2.4 inches (6 cm) from Earth. During the walk, the asteroid belt starts 17 yards (paces) past Mars and lasts for 26 yards (23.7m). On average, the asteroids are 6 inches (15cm) apart at this scale and vastly smaller than the pinheads for even the largest asteroid. The mass of ALL of the asteroids in the asteroid belt are estimated to be just 3% of the mass of the Moon. For Proxima Centauri, pick somewhere roughly 3,990 miles (6,421km) from where you are doing the walk, as at this scale, that is how far the nearest star is from Earth. This really shows just how BIG the solar system is and just how small even the planets are. Yet that spacecraft are routinely sent to them, shows the accuracy that space agencies need.

Me too, think about 7 Years ago, i was not the only one, but i prefer with the Colour's

They have to-scale solar system models all over the place. But it's still a good idea.

Yeah, I also started conceiving a scale model of the solar system about a decade ago, half the size of this one. All I have done so far is to find household objects to represent the planets. On my scale Jupiter is a softball, Saturn was turned on a lathe to get the shape right, about the size of a mandarine/tangerine. Never did finish it...

Zurich has had one for about 30 years.

don't forget Uranus is directly in front of the Bridgewater town hall.

Being in the USA I bet it is in some random measuring system that no one else understands.

@@stevenstart8728 Actually, and probably because they are right near the Canadian border, their brochure lists positions in both miles and kilometers.

@@stevenstart8728Plus in all scientific mediums it is standard to use metric… even in the US

Great to hear, this is exactly why I wanted to make this video. Enjoy.

@@StefanDrury I certainly will, as a space nerd lol

Yeah, a lot of people have no idea how really small planets are compared to our star. Sun could fit inside 1.3 million Earths, 21.2 million Mercury, 1.5 million Venus, 7 million Mars, 1.000 Jupiter (1300 Earths in 1 Jupiter), 1,700 Saturn, 22.000 Uranus, 1,800 Neptune. Also Ganymede (Jupiter III moon) and Titan (Saturn VI moon) are both bigger than Mercury. It's hard to even imagine and don't get me started on other planetary systems even in MIlky Way let alone other galaxies. I love that you and your son share that awesome hobby!

At this scale, biking is multiple times the speed of light, so it would take way more than half a year

At this scale light travels 1.08 km/h, with bike you can go 20x the speed of light in this model. Proxima Centauri is about 4 light years far from Sun, that with this speed of bike you should be there in 76 days (365*4.2/20)

It's not mind boggling to how big all of space really is. And how much of space we will never see EVER because it's moving away from us so fast its light will never ever get to us.

Whoops. Even in metric, mistakes can be made.

So much for metric being easier. 😏

@@notahotshot well 0,0906 inches for you Americans.

@@notahotshot It is, you just move 10^+/-1 while meter is 10^0, dm is 10^-1, cm 10^-2 and mm 10^-3 which translates to 10mm being 1dm, 10 dm being m so if you go down from let's say 2 meters and want to get mm you move "0" 3 times which gives you 2000mm. If you convert the lower unit you move "0" to the right, while converting to lower unit you move "," to the left.

and going up km 10^3, Mm 10^6, Gm 10^9 Tm 10^12 (there is also 10^1 which is dam [decameter] and 10^2 hm [hectometer] but these aren't used even in Physics and Math at high level until you're going for PhD but it's also uncommon)

Great Idea

Actually, only Saturn is out of the line, because Tali's Golf course, but rest are more or less in line. You can see Sun from all planets, it may take binoculars, clear day and no leaves on trees.

Neptune is also off to the side (on the opposite shore of Laajalahti bay from Uranus). But it makes for a nice bike trip.

Also I think Neptune serves as the counter-example to "you can see the Sun from all the planets". Had a look with Street View; you can just about see the top of the Digia building which is about 100 m from sea level, and the Sun model is a bit over 50 m.

Mars is Earth's sister planet, Venus is considered our twin. Venus is the same size as Earth and that's where the similarities end, Mars shares its geographical composition with Earth. Of all the planets in the solar system, Mars is the most Earth-like in terms of its water patterns. Mars has polar ice caps that grow and recede with the seasons and has evidence of water channels similar to those on Earth today. Terrain: Mars is mostly ancient, cratered highlands.

@@dosmundos3830 Good points. And Mars is quite small, only about twice the size of our moon. I wonder if that's why its core eventually died , losing its magnetic field which allowed solar winds to strip away its atmosphere

Our sun does not have an official name according to the International Astronomical Union. And according to them, "Moon" is the official name of our natural satellite in English. Also Sol and Luna are not used in English for official scientific writings. I agree that Sol and Luna could be used as official, since we do use terms as lunar and solar, but that is not the case yet.
