Meteors

Meteors are a notoriously hazardous weather. Huge rocks will fall from the sky, dealing 1000 blocks to both player and blocks.

Only some planets/biomes can have meteors.

Extreme caution is advised when building on planets with Meteors. If not protected by a Field Generator, player-constructed buildings can be seriously damaged. No block except Dead Core can survive being hit by 1000 damage from a Meteor (the strongest craftable block in the game, Diamond Block, has 84 hitpoints).

This weather has a variation called "Large Meteor", which ends more quickly, but causes an even larger impact area.
