Venus

Some basic facts:

• radius ~ 0.95 R_Earth
• mass ~ 0.82 M_Earth
• distance from sun ~ 0.7 AU.

How about its density and escape velocity?

Thus Venus is something like a sister planet to Earth.

• 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 motion ?
How about its interior ?
How about its atmosphere like?
Why is it so hot (730 K)?
What does its surface look like?
