Mars. Venus is too hot--hottest planet in the solar system also has very poisonous clouds for an atmosphere. Mercury has no atmosphere. The other planets are gas giants--intense pressures and gravity with no real solid surface.
The dwarf planet Pluto is smaller than our moon, but very far away. Mars would be the easiest to visit. And of course, the dwarf planet Eris and the other planets farther than Pluto are outta the question
Earth is the ONLY planet suitable for humans.
The third planet from the Sun is Earth. It is the only known planet to support life and is the largest of the four inner planets in our solar system. Earth has a diverse range of ecosystems and is home to millions of species, including humans.
No man or Woman has ever stepped on another planet. The only celestial body that humans have been to (other than Earth) is the Moon.
Out of the four inner planets, Mars would be the one that would be visited most easily. Although Venus comes closer to our planet, it has a crushing surface temperature of 93 bar, 93 times that of Earths. It also has the highest surface temperature of all planets. You would need a pressure suit and breathing gear for Mars, but the conditions would be far less hostile.
No, he traveled to the Moon, which is not classified as a planet. Though technically, the Earth and Moon could be classified as a double planet.

The planet is worse off with humans.
Earth is the ONLY planet suitable for humans.

Right here from Earth.
COLD it is way to cold for a human/humans to live there. Earth is the perfect temperature for humans to live on and of course Earth is the 3rd planet from the sun.
