Outer space

Outer space is a term used to describe everything existing outside of Earth's atmosphere. It mostly consists of empty space with clusters of stars, but also solid matter such as comets and meteoroids.
The basic observations of astronomy have given an understanding of planetary movements as well as the ability to make simple predictions, such as calculating the arrival of comets, forecasting solar eclipses, and distinguishing waxing and waning moons. The positions of various celestial bodies relative to Earth have a significant impact on bending and spirituality.
