      Some are freezing (because they are so far from the sun) and some aren’t solid – just gas.

      if you’ve got air, you could survive a few hours, but you’d get hungry and thirsty quite quickly, and need shelter. If might be much too hot or too cold, and without an atmosphere you might get sunburnt by cosmic rays. so you would need a lot of equipment to live for a long time on another planet.

      Lots of reasons, but mostly the lack of water… we need water to live and also they are either too hot or too cold. Mars can get to around – 120 degree Celsius… brrr…. Venus is the hottest planet reaching over 400 degrees Celsius on the surface.

      For lots of reasons, because it’s too cold, because there’s no water, because there is too much of the dangerous UV rays from the sun hitting the surface of the planet, because the gravity is too strong so anyone would be crushed. But the universe is a big place so there should be plenty of other planets where we could live, we just have to work out how we find them and get to them.
