This is Triton in ther Solar System of Earth from the Earth Directorate . The Year is 2513. Physically Triton is almost exactly the same as our own Triton. That means it's amazingly cold -235 C. or -491 F. It's gravity is 1/2 that of Luna, and it's atmosphere is 1/70,000 the pressure of Earths.
Triton has a retrograde orbit and it's composition suggests that it's a captured dwarf planet, like Pluto.
The gate here opens in a standard dome. The dome hasn't been visited for 10,000 years. There's dust in the floor anthe remains of what looks like an ancient wood debris that crumbles at the slightest exxcuse.
Outside the dome, there's life. Some ancient Terhmelern created plants that would grow and thrive in this environment. They grow very, very, very slowly and they're basically complicated ice. Going above -100 C would kill them, and more than 1/6th gwould break them. But if all else remains unchanged these weird super cold ice flowers will be there in billions of years.
No one on Earth has any idea this is there. Triton was mapped, but there are easier places to mine water ice if you're into that sort of thing. Triton has been neglected for 300 years.
