The freakiest thing about Mars, IMO, is its rotation speed. 25 hour day. Roughly just one hour away from Earth's. Is that not remarkable?

- elihu 5y agoCloser than that: it's about 24 hours 37 minutes. I don't think that's all that strange, but it is at least fairly convenient for when people start going to Mars. What I find a whole lot stranger is that Earth, Venus, Saturn, Neptune, and Uranus all have a surface gravity of around 10 m/s^2 plus or minus about 14%. That's either a heck of a coincidence, or there's something about planet formation that favors that particular outcome.
