Astraeus

Astraeus is an imaginary planet that orbits the star Alpha Centauri. It is the fourth planet from the star, so it is very far away from Earth. Astraeus is made up of rocks, ice, and dust. Astronomers believe that Astraeus has an atmosphere similar to other planets in our solar system, with clouds, storms, and winds. Astraeus is too far away for people to travel to, because of how far it is from Earth. Scientists can only study it from a telescope or other instruments in space. They believe that Astraeus could be a great place for future space exploration, because of its distance from Earth.
