Can humans land on Uranus?

As an ice giant, Uranus doesn't have a true surface. The planet is mostly swirling fluids. While a spacecraft would have nowhere to land on Uranus, it wouldn't be able to fly through its atmosphere unscathed either. The extreme pressures and temperatures would destroy a metal spacecraft.

Can humans live on Uranus?

There's no process inside Uranus, like volcanism on Earth, that would give life inside the planet a form of energy. Life on Uranus would have to be vastly different from anything we have here on Earth to be able to survive.

What planet has been removed?

The International Astronomical Union (IAU) downgraded the status of Pluto to that of a dwarf planet because it did not meet the three criteria the IAU uses to define a full-sized planet.

How long will Earth survive?

At the current rate of solar brightening—just over 1% every 100 million years—Earth would suffer this "runaway greenhouse" in 600 million to 700 million years. Earth will suffer some preliminary effects leading up to that, too.

Is Pluto livable?

Potential for Life

The surface of Pluto is extremely cold, so it seems unlikely that life could exist there. At such cold temperatures, water, which is vital for life as we know it, is essentially rock-like. Pluto's interior is warmer, however, and some think there could even be an ocean deep inside.
