Planets

Mercury Probes have orbited Mercury and sent photos, but don´t look for human lading. Mercury is too hot. And solarradiation.

Venus - Under Venus´s thick blanker of clouds, temperatures rech about 900 degrees F.  Air press is over 90 times that on Earth.

Earth -  Is a only planet has oxigen from human to live

.

Mars - Mar is cold and frosty.  Ist air is mosly unbreathable carbon dioxide.  Dust storms are frequent.  But it 's fairly close, and may have water underground.  That s why it  s worth a try.

Jupiter - Jupiter doesn t have a surface to land on!  It s a huge ball of swirling gas above a deep, liquid ocean.

Saturn  -Another ball of gas and liquid, like Jupiter.  And it 's farther away.

Urano, Neptuno  - Too far.  Too cold.  Too dark.  For the time being, it 's impossible to think of visiting outer planets.
