It’s far smaller, with only 4% the mass of even tiny Mercury. And it has a very unplanetlike orbit from every angle.

Pluto meets two of those requirements — it’s round and it orbits the sun.

Can we land on Pluto?

Unlike gas giants Jupiter and Saturn, and ice giants Uranus and Neptune, Pluto’s surface is a solid one. This means that if humans could get a space ship all the way to Pluto, the ship could land on Pluto. And, once the ship has landed, humans could exit the ship and stand on the surface of the planet.
