Do lava planets exist?
There are no known lava worlds in the Solar System and the existence of extrasolar lava planets remains theoretical. Several known exoplanets are likely lava worlds, given their small enough masses, sizes, and orbits.
What planet is green?
Uranus is blue-green in color, as a result of the methane in its mostly hydrogen-helium atmosphere. The planet is often dubbed an ice giant, since at least 80% of its mass is a fluid mix of water, methane and ammonia ice.

Is an hour in space 7 years on Earth?
The first planet they land on is close to a supermassive black hole, dubbed Gargantuan, whose gravitational pull causes massive waves on the planet that toss their spacecraft about. Its proximity to the black hole also causes an extreme time dilation, where one hour on the distant planet equals 7 years on Earth.
Do you age slower in space?
We all measure our experience in space-time differently. That’s because space-time isn’t flat — it’s curved, and it can be warped by matter and energy. … And for astronauts on the International Space Station, that means they get to age just a tiny bit slower than people on Earth. That’s because of time-dilation effects.
