Asteroids are floating minerals found in space. There are four types of asteroids in Space Age: metallic, carbon, oxide and promethium. They are immediately seen when the player is present at a space platform. If a space station is being boosted through space with a thruster, asteroids are encountered much faster. When an asteroid collector is present at a space station, small asteroid chunks can be collected for its chunks of resources. The resources collected from asteroid chunks can be fed into a crusher, grinding the chunks into useful resources.

When traveling through space, the space platform can enter a dangerous asteroid field, where many asteroids can hit the player's platform and destroy it. This means that turrets with well-stocked ammunition and asteroid collectors should be properly placed around a platform to ward off the asteroids.

The density of asteroids can be seen by going to the Remote View > Surfaces > Space Map and alt-clicking on the interplanetary route to bring up the route in Factoriopedia, or by searching "route". The graph will show a white vertical line overlay on the asteroid graph corresponding to the ship's position when underway.

Asteroid Types

Name	Info
Asteroid Chunks	Can be grabbed by the collectors. Do not have health and are instantly destroyed on contact with the space platform. Do no damage.
Small Asteroids	Do not spawn naturally. Produce chunks on destruction. Do small damage on contact with the space platform. Health: 100 Resistances: Electric: 100% Explosion: 50% Fire: 100% Laser: 20%
Medium Asteroids	Spawn in space and in orbit af planets other than Nauvis. Split into small asteroids when destroyed. Do medium damage. Can destroy several foundations before expiring. Health: 400 Resistances: Electric: 100% Explosion: 30% Fire: 100% Laser: 90% Physical: 10%
Big Asteroids	Spawn in space beyond Fulgora. Split into medium asteroids when destroyed. Do large amount of damage. Can go right through the space platform destroying everything on its path. Because of the high flat physical resistance, gun turrets are ineffective against them. Health: 2000 Resistances: Electric: 100% Explosion: 10% Fire: 100% Laser: 95% Physical: 2000/10%
Huge Asteroids	Spawn in space beyond Aquilo. Split into large asteroids when destroyed. Will absolutely destroy the space platform if it is not equipped with a turret that can overcome its enormous flat physical resistance, e.g. a railgun turret. Health: 5000 Resistances: Electric: 100% Explosion: 99% Fire: 100% Laser: 99% Physical: 3000/10%

Asteroid Chunks

Asteroid chunks are the smallest asteroids found in the game. They are the only source of resources in space, so a platform should be equipped with asteroid collectors and crushers to have any kind of sustainability. Just like any asteroids, they come in four variations:

• Metallic - can be processed into iron ore. After the advanced asteroid processing is researched, can also produce copper ore.
• Carbonic - can be processed into carbon, and later additionally into sulfur.
• Oxide - can be processed into ice, and later additionally into calcite.
• Promethium - cannot be processed, goes directly as a component to the promethium science pack.
