Some basic facts:
How about its density and escape velocity?
- radius ~ 0.95 REarth
- mass ~ 0.82 MEarth
- distance from sun ~ 0.7 AU.
Thus Venus is something like a sister planet to Earth.
How about its motion ?
- This makes sense according to our picture of how planets formed since
Venus formed from the material just a little closer to the sun than Earth.
How about its interior ?
How about its atmosphere like?
Why is it so hot (730 K)?
What does its surface look like?
