"Hung low in orbit, masses of ground and various parts of the world provide a secluded and distant point for research."

Planetoids are structures added by the Calamity Mod that are created in the Space layer during world generation. They are floating spheres of blocks with varying sizes and materials, often containing valuable loot. There are 6 different types of planetoids: the Main Planetoid, Life Crystal Planetoids, Ore Planetoids, Jungle Planetoids, Beehive Planetoids, and Mushroom Planetoids. After defeating the Moon Lord, a few new planetoids made entirely of Exodium Clusters and Luminite with two distinct variants; one with the middle filled with Luminite with a crust of Exodium Clusters and/or a planetoid with Exodium Clusters making up most of the planetoid with sections filled with Luminite along with small outcrops of Exodium Clusters on the surface. This content originates from the Calamity Loot Swap addon. Additionally, all Planetoids will generate veins of Cosmilite Slag, which are used to craft Cosmilite Bars. Most planetoids are generated within the middle 3rd of the map, although sometimes planetoids can be generated farther out from the center.

Main Planetoid[]

Main Planetoid

The Main Planetoid.

The Main Planetoid will always be located around the center of the map. It is the largest of the planetoids, and the size of the planetoid scales with the map size. At the center, there is a unique Space Bio-center Lab, containing the schematic used to craft the second tier of Draedon's arsenal and decrypt the third schematic.

Life Crystal Planetoids[]

Life Crystal Planetoid

A Life Crystal Planetoid containing diamonds.

Life Crystal Planetoids are the smallest and most common of the planetoids and are made of stone that is covered in a random type of moss. They will always contain a Life Crystal encased in either Platinum Brick or Gold Brick and will typically contain a cluster of a specific type of gem; however, there is a small chance that a gem cluster will not be generated.

This section describes old mod content that was removed or replaced. The information here does not apply to the current version of the Calamity Mod.

Ore Planetoids are large planetoids containing streaks of a Pre-Hardmode Ore. The ore will always be the counterpart to one of the Pre-Hardmode ores generated in its world (for instance, if the world generated with Copper, a planetoid would contain Tin). They occasionally have a campfire and a tent on top of them or a pyramid-like structure (comparable to an Enchanted Sword Shrine) constructed of Stone Slabs with Shadewood Lamps on either side.

Jungle Planetoids[]

Jungle Planetoid

A Jungle Planetoid.

Jungle Planetoids are average sized planetoids made of mud and Jungle grass. They always contain a pool of water in the center with an accompanying Water Chest, and can generate with Jungle Trees on top of them. After Golem has been defeated, Miracle Fruit will begin generation inside.

Beehive Planetoids[]

Beehive Planetoid

A Beehive Planetoid.

Beehive Planetoids are very similar to Jungle Planetoids, as they are both made of mud and Jungle grass and are around the same size. The Beehive Planetoid, however, will contain a Bee Hive with some honey and a Honey Chest. Like Jungle Planetoids, Jungle Trees can generate on top of Beehive Planetoids.

Notes[]

Tips[]

  • Because the main planetoid is always close to the center of the map, the player can easily find and reach it at the start of the game by building a line of ropes up from their spawn point. This allows them to acquire a large amount of herbs for brewing potions in the early game, including fireblossom, which would otherwise require reaching the Underworld.
  • Like with Floating Islands, Gravitation Potions are an extremely useful asset in locating Planetoids.
  • Having a Mushroom Planetoid in your world is also very useful, as it allows Crabulon to be fought before finding the Glowing Mushroom biome underground and allows the Truffle to be acquired easily.

Trivia[]

  • A concept theme for the Planetoids has been made by DM DOKURO, known as Blessing of the Moon, but it is not intended to be a part of the mod.
  • A small Planetoid is depicted in the Space's Draedon's Log.
  • The Cinderplate in the the center of the Main Planetoid is based off of the core of the Earth.
