A gas giant in the distance. There appears to be a lone chunks of rock spread about in the almost concerningly thick atmosphere. Vesta is the gas world, and all about gases.

Platform Mode, which removes the rock formations and places you on a lone platform. Realistic Gases Mode, which replaces all the icons and world generation with more realistic colors.
