You are a probe sent to explore space. Includes 2 solar systems.

KTHO-130: A Giant star.
Kthonna: The first planet from the sun. Consists: 80% molten rock and 20% obsidian
Mogdud: The planet you were sent from.
???: A lost probe with a unknown origin. Seems pretty old,since it's REALLY rusty.
Angronian: A REALLY cold planet. Consists: 50% ice and 50% purple gas. There's also a tornado rampaging on the planet.
Mathronian spaceships/ drones: Stange,circular-shaped ships and drones. Nobody knows where they are from. They move aimlessly around space and seem to be nearly indestructible.
Moltrian: A star smaller than ours. Seemingly slowly moving towards our solar system.
Alkonost: An asteroid orbiting around Moltrian.
Mathronian base: Largest of the mathronian ships. Said to be the base of mathronians. Larger than ANY objects ever seen by the national telescope.
