Wormhole Facts for Kids

Outer space, or simply space, is the expanse between all celestial bodies, including Earth, in our Universe. There is an enormous amount of space in our Universe. The Universe itself has a diameter of 93 billion light-years, around 125 billion galaxies, an estimated 200 billion trillion stars (200 sextillion), and countless celestial bodies. Even with all that matter in our Universe, almost the entire universe is made up of space. Don’t think of space as empty space, it is not completely void of matter. Outer space is almost a near perfect vacuum with a very low density of particles, such as the plasma of helium and hydrogen.

Outer space may sound empty, but it contains tons of different celestial bodies and objects, many we haven’t even discovered yet. A few of the celestial bodies found in space are black holes, galaxies, stars, and planets. A black hole is a super dense region of space and time that has such a strong gravitation nothing can escape it, not event light. A galaxy is a gravitational bound system of stars, rotating around a supermassive black hole. A star is a bright sphere of plasma being held together by gravity. A planet is collection of remnants from the formation of a star and a planet can be a solid body or a gas body.
