On the other hand it has much more mass than Earth and so there is slim possibility it has dense atmosphere. I believe dense atmosphere to be more important that perfect temperature for habitability.
Actually, what I meant is it is easier to build for cold than it is to build for vacuum. Atmosphere also contains many important elements which would be hard to get from planet's crust.
As to Venus... it is CLOSER to the Sun than Earth is, not farther.
I'm aware of the order of the planets, what I mean to say is Venus's climate has much less to do with its distance from the sun than its atmospheric composition. It'd be cooler if you moved it to Mar's orbit, but still much hotter than Earth, even although solar radiation is dropping off proportionally with r squared.
