[2] The same study also speculated that Venus may have once been a habitable desert planet as recently as 1 billion years ago.
[2] It is also predicted that Earth will become a desert planet within a billion years due to the Sun's increasing luminosity.
[2] A study conducted in 2013 concluded that hot desert planets without runaway greenhouse effect can exist in 0.5 AU around Sun-like stars.
In that study, it was concluded that a minimum humidity of 1% is needed to wash off carbon dioxide from the atmosphere, but too much water can act as a greenhouse gas itself.
[3] The concept has become a common setting in science fiction,[4] appearing as early as the 1956 film Forbidden Planet and Frank Herbert's 1965 novel Dune.
