TRAPPIST-1d is a rocky, Earth-like planet, meaning that it is roughly the same size and mass as our home.
TRAPPIST-1d has a radius that is about three quarters the size of Earth, and a comparable mass just a little heavier. Planets like this are of intense interest to astronomers because they are so like our own. In many respects, this planet is the most habitable exoplanet found so far. It is not large enough to retain light gasses like hydrogen and helium, which could destroy nascent life and it is comfortably situated in the star’s habitable zone.

It's a great planet and it's also great knowing there's millions more just like it :)

@nathanroberson 11 месяцев назад

Thanks you

The amount of knowledge we've gained since a couple of decades of exoplanet research makes me think how much more we'll get to know when we get new and better dedicated telescopes in the coming decades.

Again great video thank you Tony and for the visuals i see what did you there nice job 👍🏼

@deepastronomy 11 месяцев назад

LOL You caught me. Getting these out everyday means certain compromises 🌔

How could anything survive with 4.3% of the light we get?

@callumbush1 11 месяцев назад

There's life at the bottom of the ocean which gets zero light!

@RolfStones 11 месяцев назад

The planets are much closer, so that compensates. As I understand it, the main problem with red dwarfs is that they can send relatively big bursts of radiation and do that regularly. So some think that would make it hard to have a good atmosphere or that it may kill life in such a burst...

@alexisdespland4939 11 месяцев назад

but i am not on an exoplanet so how can i possiblt listeb to his show. lol

@geemanbmw 11 месяцев назад

I'll never say it's a waste of time but red dwarfs are a waste of time lol if we truly want to find life as we know it and that would be around any G type star or around a K0V-K03, K type star or even the smallest of F type stars especially F8V-F9V

@RolfStones 11 месяцев назад

Lol, I see what you did there. I am skeptical as well with red dwarfs. But untill we know they're not habitable, we should try to find out. And we don't really have the tech to take a good look at lots of G or K stars...
