Trenix

Trenix is the last dwarf planet and last object of Holas.

Moons
It has no moons, there is no explanation why, but there simply is just none around this dwarf planet.

Craters
There is a small amount of craters that are a few km across though there is not a lot that doesn't mean the surface is young, it's actually quite old.

Mountains
There is plenty of tall old mountains that had formed 4.8 billion years ago, even though some of them were once volcano's they did sadly go extinct and go lowered to mountains.
