No. There is no way to eliminate all life on Earth even if we wanted to. It would take a massive asteroid impact to do that.
It is a rocky planet or terrestrial planet. Any planet before Mars is terrestrial and any planet after Mars is a gas giant.
Uranus is a gas giant planet. There is no oxygen there and northing to stand on. Where atmospheric pressure is in a range that humans could survive, it is extremely cold.
No. Neptune is a gas giant planet. There is no way it could be reclassified as a dwarf planet.
Neptune is a gas giant, so it is uninhabitable to humans.
Humans could not live on Saturn because it is a gas giant composed mostly of hydrogen and helium with no solid surface to support life. The extreme atmospheric pressure and temperatures would also be inhospitable to human life.
Maybe one of its orbiting moons could, but the planet itself is a gas giant. No.
Gas giant planet.
Pluto is classified as a dwarf planet, not a terrestrial planet or a giant gas planet. It is primarily composed of rock and ice, similar to terrestrial planets like Earth, but it lacks the characteristics of a true terrestrial planet or a gas giant.
The planet Uranus is called an ice giant planet.
Saturn is a gas giant planet, meaning it is primarily composed of hydrogen and helium with a small rocky core at its center. It does not have a molten surface or significant internal heat source like a molten giant planet.
No, Jupiter has no surface to build on as it is a gas giant planet.
Jupiter is a gas giant planet.
