Venus is close to earth in that it has a dense atmosphere and is about the same size. Somewhere in the atmosphere is probably a layer that has enough oxygen, pressure, and is shielded from enough radiation for life to survive.

Mars is very different from either of earth or Venus.

It has 1% of the atmosphere as earth, what atmosphere it does have has nearly all CO2, and it only has 1/3rd the gravity. Its surface is constantly blasted by enough solar radiation to effectively sterilize anything on the surface, and the ground is full of toxic salts. I would much rather be in a cloud on Venus than anywhere on the surface of mars.

I was speaking of their proximity in space, sorry for not being clear. Very good info regardless

It was pretty clear to me that you meant spatial proximity.
