Asteroid (Block)

Asteroids are blocks unique to the Space biome. They spawn in clusters resembling an actual asteroid in the Space biome, creating an Asteroid (the structure). There are 2 in a small world, 3 in a medium world and 4 in a large world. Only one, however, contains the special Mysterious Smoking Asteroid block, which is part of the process to summoning The Doom. They are very vulnerable to explosions unlike the smoking type, which can not be exploded at all.
