Why do planets (not) lose atmospheres?

- We often hear that the magnetic field is very important for our planet, and that without it we would lose our atmosphere, just like Mars did. So then why did Venus not lose its atmosphere and it's even thicker than the Earth’s atmosphere? Let’s talk about how planets lose or keep their atmospheres, and why there is such a big difference between Earth, Mars and Venus.

Why am I the first to comment? Your content is amazing and I thank you immensely for it
Thank you!
found your channel when I was looking up CMBs and I have to say your visuals and explanations of things are really good and even an idiot like me can mostly understand.. 👍
Thank you!
So the reason Venus doesn’t loses it’s atmosphere way more than earth does (even tho is does not having a strong magnetic field, is closer to the sun and have a lower gravity) is because most of it’s atmosphere is CO2? And CO2 is a heavier molecule (than oxygen, nitrogen and of course hydrogen) so it’s tougher to rip it out of venus? Please someone correct me if I got this wrong, I’ve have this question for years now
💯💯
Another excellent video by Andre
indeed:)
This video made me smarter🤣 Thanks!
I’m working on constructing a small scientifically accurate habitable world and was trying to figure out on how to keep its atmosphere, this actually really helped thank you so much, you’re so underrated, keep up the good work 👍
Thank you!) Glad I could help
This is a great explanation. Thank you.
Amazing. Not sure why but all of a sudden I started wondering why we even have an atmosphere on earth. And if gravity was enough of an answer given that Mars doesn’t… which led me here. I have to rewatch this but now I have a clearer picture. Thanks for providing this info!
Ooh, a detailed breakdown of Venus's potential runaway greenhouse effect would be super cool!
finally someone that reeeally explained it.. THANK U. ❤
Great video 👍
a new vid on my favourite channel ^^)
wouldn't the solar wind also add to the atmosphere? All the charged particles are obviously not moving at the same speed. The slower ones would collide with the slow molecules on Venus and stay in the Venus atmosphere, thus adding to it. This would balance what is lost to higher speed solar wind particles. What is wrongg with this reasoning?
Love it
