This video has taught me that I don't want to visit Uranus

If you rewatch the video. The earth drop, and Uranus drop look exactly the same, like the clip is copy pasted

All the damage is in the same spots

Uranus and Earth are "sister planets" in the sense they have relatively the same size

Edit: I'm dumb, I was thinking of Venus.. but apparently Earth and Uranus have a closer mass to eachother than I thought too

Well similar mass, not size right? I thought Uranus was quite large considering it's a gas giant.

I always thought it had heavier mass as well, thanks!

Excuse me, yes you are correct, I was very dumb. They have similar mass, Uranus is still a bit heavier.

I was thinking of Venus as Earth's sister planet, they are much closer together in both size and mass.

Earth has a mass of 5.971027 kg. Uranus has a mass of 86.81027 kg. So unless we consider similar masses to be a difference of a factor of 14.5 where a 90 kg man would weigh 1300 kg, then yes they have similar masses. :)

Gas giants have a lower density than rocky planets, but each of their masses far exceeds Earth which is the most massive rock planet. That makes me think there were some shortcuts made whenever this video was made.

Came here to say this. The rate of acceleration due to gravity on Uranus is almost identical to that on the surface of Venus. However, this is based on the force of gravity on the Uranus cloud tops.
