The Mystica Universe

Clusters
Clusters are large areas within the  galaxy that contain one or more solar systems.

Asteriods
Asteroids are minor planets. They are in direct orbit around the Sun. They vary greatly in size, from almost 1000 km for the largest down to rocks just 1 meter across.

Meteoroids
A meteoroid (/ˈmiːtiərɔɪd/)[1] is a small rocky or metallic body in outer space. Meteoroids are significantly smaller than asteroids, and range in size from small grains to 1 meter-wide objects. It becomes a meteor when it enters a planet's Atmosphere.
