  Venus was habitable for about 3 billion years, until about 700 million years ago… it stopped being habitable because of Jupiter.

  Considering there’s a good chance Jupiter obliterated an entire planet of living organisms… yea it’s not as nice as it seems

    But all of its atmosphere leaked out into space

    Wasn’t that because Mars isn’t heavy enough?

      Well, its mass certainly contributed to it losing heat more efficiently. But Mercury (much smaller than Mars) and Ganymede (around the same size as Mars) both have a magnetic field, so there are a lot of other factors at play. Something to do with a change in the chemical composition of Mars’ mantle, I’m not so familiar with it though.
