The Earth is the only planet humans can live on without artificial support 24/7. Humans couls possibly live on Mars, but would need to build airtight accommodation and import all food and heating requirements. I think water has been found underground on Mars.
The basic requirements of human beings are air and water, if these two things are present on any planet, then it can be possible to live on that, but unfortunately our astronomers did not able to find any of such planet, but in future it can be possible. So hope for the best!
yes if we do not colinize another two planets by the year 2058 we will probly all die due to overpopulation and polution
Two Planets was created in 1897.
The other two planets are Mercury and Venus.
The difference in the gravity of the two planets

Two types of planets are terrestrial planets, which are small, rocky planets like Earth, and gas giant planets, which are large planets primarily composed of hydrogen and helium, such as Jupiter and Saturn.
Mercury and Venus are the two planets that have no moons.
A Dweller on Two Planets was created in 1905.
The inner planets do not have many moons because what could become moons is usually trapped by one of the outer planets gravitational pull, lost in the asteroid belt, or crashes into the inner planets.
In our solar system, Mercury and Venus are the two planets which do not have moons.
