Planetarium

type in a name and press enter to visit that planet
click the question mark (or press 0) to go to a random planet
drag the slider up and down (or use the arrow keys) to change the planet's temperature
click the little planet in the corner (or press tab) to change between normal view and temperature view
click the other buttons to see what they do (or press 1, 2, 3, 4, or 5)
at the right temperature, each planet is home to some form of life
and there are over 150 secret planets to find

this is a planet generator, not a game
