With respect to the subject title, let me tell you something about our celestial neighbours and see what you can infer.
Mars is smaller and farther from the sun than we are. Its geomagetic dynamo appears to have shut down which has allowed the solar wind to scour its atmosphere away over tens of millions of years. Coupled with the gradual shutdown of the geological activity that would replenish the atmosphere from planetary outgassing, the result is a cold, barren world.
However, the volcanos indicate that this was an active world, the magentisation of its rocks show that it did have a magnetosphere and evidence abounds that the planet had a substantially thicker, warmer and wetter atmosphere in the past. Its day is only slightly longer than ours and clearly it would have been the most Earth-like environment possibly even a place life may have took hold before premature old age robbed it of its vigour. It shows its aged surface for all to see, giving tantalising glimpses of a much friendlier past.
Venus, on the other hand, is considerably more massive than Mars, that extra mass allowing it to hold down a dense atmosphere. A dense, noxious atmosphere that at the mean surface level was more than enough to crush a submersible after an hour.
It's a crushing inferno of a planet, worse than Dante's furthest stretch of the imagination, with impenetrably dense clouds of vitriol shrouding it from closer examination. Its surface temperature is hot enough to melt lead as it lazily rotates (backwards!) in a day that's actually longer than its year.
Despite being closer to the sun than Earth, conditions at the surface are gloomy, so much of the light is absorbed or reflected long before it meets the hellish surface.
The surface itself is deceptively young looking. Every few hundred million years its speculated that it melts due to the lack of tectonic processes to liberate the interior heat, resurfacing vast swathes of the planet with boiling magma that tortures the already chthonic enviromnent even further. Venus really is as close to classical hell as any terrestrial planet can be.
So, men are from Mars and women from Venus. You've seen the environments of both. Make up your own minds ;-)
