Is there another solar system in space beyond ours?
Yes, there are many solar systems beyond ours.
A solar system is a star with planets, asteroid and comets orbiting around it.
We have started to detect planets and belts of comets around other stars. Space telescopes have paved the way for detecting planets around other stars which we call exoplanets.
The Kepler telescope was specifically designed to detect exoplanets. It has discovered over 3,000 other solar systems.
Our nearest neighbour Proxima Centauri is known to have a planet orbiting it. So, it would seem that solar systems are quite common.
