Asteroids

Homas: Big asteroids do spawn in stationary Aquilo orbit. This is useful to know for defenses when making refuel/hub stations in orbit with the new 2.1 mechanic of much faster transferring between platforms.

{{About/Space age}}
[[File:asteroids_anim.gif|right]]'''Asteroids''' are floating minerals found in space. There are four types of asteroids in [[Space Age]]: metallic, carbonic, oxide and promethium. Promethium asteroids are only encountered when en route to the [[shattered planet]]. Asteroids appear from all directions around stationary [[space platform]]s. [[Asteroid collector]]s can collect [[Asteroids#Asteroid chunks|asteroid chunks]], which can be fed into a [[crusher]], grinding the chunks into useful resources.

While traveling through space, asteroids will appear in front of the space platform at a much higher rate and damage it on contact. [[Turret]]s placed towards the north edge of the platform can prevent damage by breaking the asteroids into smaller pieces until only the harmless asteroid chunks remain.

The density of asteroids can be seen by going to '''Remote view''' > '''Surfaces''' > '''Space Map''' and clicking on an interplanetary route between two planets, or by searching "route" in [[Factoriopedia]]. The graph will show a white vertical line overlay on the asteroid graph corresponding to the ship's position when underway.

| Asteroid chunk
| Harmless. This is the only asteroid type that spawns in orbit over [[Nauvis]].

Does not have health and is instantly destroyed on contact with the space platform.

Can be collected by [[asteroid collector]]s.

Does medium damage. Can destroy several tiles of space platform foundation before expiring. Heavily resistant to laser damage.

| Big asteroid
| Spawns in space beyond [[Fulgora]] and [[Gleba]] also spawns in stationary orbit of [[Aquilo]]. Splits into three medium asteroids when destroyed.
Practically immune to physical and laser damage.

Does large amount of damage. Can go right through the space platform destroying everything in its path. <br>Because of its high flat physical resistance, [[gun turret]]s are ineffective against them, and it has even higher laser resistance than its medium counterpart. [[Rocket turret]]s are usually more effective.

| Huge asteroid
| Spawns in space beyond [[Aquilo]]. Splits into three big 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]].

== Asteroid chunks ==
'''Asteroid chunks''' are the smallest asteroid type, serving as the sole source of resources in space. Due to their size and low mass, these small chunks will not damage the player's space platform when colliding with it. These chunks come in four distinct varieties, three of which can be processed into raw materials using [[crusher]]s. All chunks can be collected with [[asteroid collector]]s. Researching [[Advanced_asteroid_processing_(research)|advanced asteroid processing]] unlocks alternate recipes which can extract additional materials.
