This article is about the biome. For the ore, see Meteorite.

A Meteorite biome is a mini-biome formed when a meteor crashes in the world. This event always occurs off-screen, leaving a crater lined with Meteorite ore for players to find somewhere in the world. A meteor event can only be triggered once the player (Desktop, Console and Mobile versions) has defeated the Eater of Worlds or the Brain of Cthulhu for the first time / (Old-gen console and 3DS versions) has broken a Shadow Orb or Crimson Heart for the first time (see the exact conditions below). Players are alerted of a meteor crash via a status message: "A meteorite has landed!"

Meteorite biomes spawn Meteor Heads, a unique enemy type, which fly toward the player and follow them as they move, passing through all blocks that they come across. The spawning of Meteor Heads cannot be prevented as long as the area is considered as a Meteorite biome, even with several NPCs nearby. However, the Space Layer can override the Meteorite biome (Harpies will spawn instead). If the player is in a Meteorite biome but also near the Space border, both Harpies and Meteor Heads can spawn.

Once most of the Meteorite has been mined away (fewer than (Desktop, Console and Mobile versions) 75 / (Old-gen console and 3DS versions) 23 blocks of Meteorite remaining; about 10% of an average meteorite site), the area will no longer be considered a Meteorite biome.



A meteorite crash site has a 50% chance of spawning (Desktop, Console and Mobile versions) after the Eater of Worlds or Brain of Cthulhu is defeated / (Old-gen console and 3DS versions) after a Shadow Orb or Crimson Heart is smashed. The biome is generally spawned at the next midnight, but it can spawn immediately if (Desktop, Console and Mobile versions) the Eater of Worlds or Brain of Cthulhu is defeated / (Old-gen console and 3DS versions) the Shadow Orb or Crimson Heart is broken between midnight and dawn (12:00 AM – 4:30 AM).

Additionally, each night has a 2% chance that a meteor will randomly fall upon midnight, if (Desktop, Console and Mobile versions) the Eater of Worlds or Brain of Cthulhu has been defeated at least once / (Old-gen console and 3DS versions) at least one Shadow Orb or Crimson Heart has already been smashed in the world. These conditions are checked upon dusk (7:30 PM).

Once the initial conditions are met, over time multiple meteors will land in a world. However, none will fall if there are already a certain number of Meteorite ores above 0 ft. The limits are:[1]
  • Small worlds: 401
  • Medium worlds: 610
  • Large worlds: 801

There are also constraints on where meteors can strike:

  • An area that laterally spans 16% (672 (small worlds) / 1024 (medium worlds) / 1344 (large worlds) tiles) of the world centered on the spawn point is protected from falling meteors.
  • Meteors will not land within 35 tiles of an NPC or a Chest.
  • They will not fall on-screen for any player.
  • They cannot fall within 50 tiles of either edge of the world or 50 tiles from the top of the world.
  • (Desktop, Console and Mobile versions) They cannot fall on the Dungeon or the Jungle Temple.
  • If the entire world is covered by these conditions (e.g., because of lots of Chests), no meteor will fall.

In searching for a valid location, the game will search a 30×30-tile region and look for 600 solid blocks within that region. Sunplate and Cloud Blocks count as −100 solid blocks; thus, Floating Islands are unlikely to be struck by a meteor. Liquid decrements the count too, so meteors are less likely to crash at the Jungle or Ocean. Thin structures such as sky bridges are not dense enough to allow a meteor impact.


  • Fulfilling the condition for a meteor to spawn ((Desktop, Console and Mobile versions) defeating the Eater of Worlds or Brain of Cthulhu / (Old-gen console and 3DS versions) breaking a Shadow Orb or Crimson Heart) several times between 4:30 AM and 12:00 AM will only have a chance to cause one meteor to fall at midnight; the event does not stack. Fulfilling the conditions repeatedly between 12:00 AM and 4:30 AM may still spawn multiple meteors, however.
  • In the Nintendo 3DSNintendo 3DS version version, the music track The Underworld will play instead of Eerie while in the Meteorite biome.
  • On the Desktop version Desktop version, Console version Console version, and Mobile version Mobile version, the background will show an animated falling meteor shortly before the impact site is generated in the world. It is not an accurate representation of where the meteorite crash site will actually be created in the world: The meteor may appear to fall to the right side of the world, but it might have landed on the left side instead.
    • The meteor will only be displayed if the condition for the Meteorite biome to spawn was fulfilled between dusk (7:30 PM) and 11:40 PM, which includes the random chance each night. It will always start falling in the background at 11:40 PM.[2]
    • Even if circumstances would prevent meteorite landings (i.e., no new Meteorite biome would actually be generated), the background meteor will always appear when the conditions are fulfilled.


For tips on defending against Meteor Heads, see Meteor Head § Tips.
  • Proper equipment, such as a tool with high mining speed (the fastest pickaxe capable of mining Meteorite available pre-Hardmode is the Bone Pickaxe; reforged to Light for an even higher speed) and protection against the Burning debuff (e.g. with an Obsidian Skull) will greatly facilitate efficient mining of the meteorite.
  • (Old-gen console and 3DS versions) Angled Meteorite ores can be touched without taking Burning damage. Leaving a block alone every few rows and angling it with a hammer will allow using it as a platform to dig deeper down. One can also dig underneath the crash site, using other block types to stand on while mining the Meteorite above.
  • Since meteors cannot fall if there are too many Meteorite blocks placed above 0 ft in the world, it is possible to completely prevent meteorite strikes by placing a sufficient number of Meteorite blocks anywhere above 0 ft.
  • There are certain areas on the map a player may wish to protect from meteorite crashes, such as player-built structures, the Ocean, the entrances to the Underground Jungle, the Underground Desert, chasms, a Living Tree, (Old-gen console and 3DS versions) the Dungeon, or the Temple. The easiest way to protect these areas is by placing down a Chest near those areas. The Chest will protect everything within a 35-tile radius. Alternatively, adding a few Cloud or Sunplate Blocks will also protect an area.
  • If a meteorite crash site cannot be located on the surface, it might have crashed into a Living Tree or a chasm in The Corruption/Crimson.


  • The music of Meteorite biomes is overridden by the theme music of The Corruption, The Crimson, Glowing Mushroom Biomes and Space when crashed there.
  • While a player, Ghost, and the death screen can block a meteor from spawning at a location if the landing spot is within frame, the spawning of the meteor can actually be seen using Golf Balls(Desktop, Console and Mobile versions) to move the camera.
  • Meteorites in a landing site will also be painted if the blocks the Meteorites replaced were painted.



  • Desktop Fixed an issue where if the entire top of your world was covered with platforms, it would prevent meteors from spawning.
