Vincent Dufault I guess it is possible I heard about a discovery about a planet orbit 3 different stars. (Or maybe it was just a suggestion by Star Wars fans. :P)
A rule of thumb about orbit stability: If the period of an object's orbit exceeds the orbital period of its parent, the orbit is unstable. In other words, the Earth can't have a moon with a stable orbit longer than a year, because the Earth takes one year to orbit the sun. So, if the Earth's orbit around that gas giant is shorter than a month, then the moon's orbit around the Earth is unstable. That region is called the "Hill Sphere." Wikipedia has a good article on the subject.
Been loving the vids so far but just a couple suggestions. Have you ever thought of pre-recording your gameplay then researching the effects afterwards then post-recording your voice over the video? You don't have to do this for every video but with a couple it would be cool to know more of the science behind it. Also would be cool to further explore the tidal forces you noticed in previous video on how it can heat a moon. Maybe have earth orbiting Jupiter and testing various orbits to find a Goldilocks zone for tidal forces.
very kewl vid :-) I've always wanted to see what it would look like if the earth was just a moon of a gas giant. also the explosions at the end were a nice touch. cant wait to see ur next vid.
no why would it turn into a star? the requirements of a star is nuclear fusion the most lickly answer would prob be a super planet or the earth would collapse on its own gravity and turn into a gas giant
If sea ice increased the sea levels wouldn't actually be effected because ice expands when it freezes. This is why cold water sinks but ice floats. The frozen water increases in volume therefore displacing more liquid water. The sea levels in this simulation were probably all out of whack because of the gravity from the gas giant increasing the tide level differential.
It didn't have as much of an effect as I thought it might have, although the moon being pulled out of orbit would be enough to cause planet wide chaos. Keep up the good work :)
Try to make a solar system like the one in Firefly and Serenity. A solar system that could have dozens of planets and hundreds of moons that might be inhabitable.
The Moon is WAY outside Earth's Hill Sphere at the beginning of the video. It's actions are the gravitational influence of the gas giant - it would have to be a lot closer to mitigate those effects.
this is quite an awesome simulator you've got here. I hope you can answer this but I am curious, can an individual like myself buy this game your playing in a store, or is this a program you solely created for yourself? I really wish to know. I love astronomy with a passion and this game your playing looks just incredible. Thanks for the videos.
Dang! I was really interested to continue seeing what would happen here. I'm pretty sure the moon got pulled back into orbit of the gas giant and you didn't seem to notice. I would like to have seen more time pass in this scenario to see how stable it would end up being over time. Then you started blowing shit up. :-(
what if earth is placed between two suns of exact same mass and same gravitational pull. will earth be in orbit or will it just be still, like how we do with magnets
I need to buy this program to do this myself, but... What if Neptune lost 90% or it's orbital velocity? What would it do to the Earth and other planets as it plunged through the Solar system and how long before Earth is no longer habitable? What would its final orbit look like (assuming it's not ejected by Jupiter or Saturn?)
It would have been interesting to know why that gas giant was losing so much mass, so quickly? Was it being acquired by the Earth, even though it was less massive than the gas giant?
No the Red Dwarf wouldnt orbit us. You do realize Champion that Red Dwarfs are many times the mass of Jupiter right lol? To answer the question tho, a lot would change. The inner planets up to Mars would maintain similar orbits, but would be a lot cooler than they are currently...as the Red Dwarf isnt as hot, and as a result, doesnt give off as much heat. So life on Earth as it currently is probably wouldnt exist. But as a result of cooler temperatures, Venus would become habitable. As for the outer planets, since the Red Dwarf is a lot less massive than our current Sun, it wouldnt be able to gravitationaly hold onto them...so they would drift away. That would have dire implications for life on Earth...I mean Venus. Without Jupiter and the other gas giants to protect us, the inner Solar System would be more susceptible to bombardment from comets and asteroids. So we would be getting hit every few thousand years, rather than every few million. So odds are, complex life never would have evolved at all.
does this program show what the sun will look like or be like when it turns into a red star before it exsploeds i kind of wanna see what the earth would be like when that happens
What if the planet positions was flipped ex. Earth and Neptune orbits switched.. I wonder if the gravity lock would keep it on orbit or would it fly out
Could you take away the moon, and give the earth a twin like planet on the same orbit as earth, but one moving slightly faster. Maybe a smaller planet perhaps. To see if we can create the moon as the theory goes.
Would like to see if there are significent climate difference between when the earth is on the near side to the sun compared to when the earth is on the far side shadowed by the gas giant while orbiting it.
what if our sun got hit by a gamma ray burst, or what if the sun was x100 its mass and all of the planets had their same orbits in proportion to the increase in size of the sun.
can you sim a double earth with the moon or other body as center of gravity. or do all kinds of moon impacts to see how bad it can get on earth. but the earth is only hit by broken off moon bits
Ah ha! I figured it out. I was using only the mouse to work the camera. For locking onto target bodies. With the mouse you're limited as to how far you can zoom in on a body. If you use the w, a, s, and d keys you can move the camera in a sort of spaceship mode. Is what it feels like. Like you're flying around. And it allows you to get as close as you want to with a body. So its all good. And I love the program by the way! So glad I got it. Its too cool.
To first question: The orbit of Venus would become unstable because of the gravitational interaction between the Sun and the star Mercury supposedly became. If this theoretical Mercury star is a small red dwarf, then Earth's climate might not be too different, but if it is a sun-like star, our planet would be too hot to host life as we know it. (Maybe Mars would be habitable, though) To second question: The star from the hypothetical second solar system would likely form a binary star system with our Sun. If the distance between both stars are too short, distant planets like Neptune and Uranus would have unstable orbits and would either fall into a lower orbit or be ejected from the solar system into interstellar space. (Might end up colliding with the Sun too, but this is quite unlikely)
they actually think that the nearest start alpha centauri's ort cloud (closest system 4 light years) is connecting with ours but we wouldent know it to much because the difference in space between the rocks in the ort cloud are the distance between the earth and the sun
How about flipping this scenario on it's head - what if the gas giant was orbiting the Earth ;-) (And, before anyone says it, I know that's probably physically impossible - but what the hell!)
What im really missing from your otherwise entertaining videos are more long time simulation of tge evolution of orbits. For example how this gas giant affects the orbits of the other terrestrial planets. This was run for like 3 days, idd very much like to see hundreds or thousands of years.
here is a great question.....can a MOON, have a moon of its own..........NOT a system where two moons are orbiting each other, and the center of gravity is outside both moons......but rather, where the center of gravity is in one of the moons, and the other is orbiting it.........i don't know if i said that correctly, but hopefully i said it close enough that you understand
