Space is fascinating
How much do you know about the Milky Way?
The Milky Way is the Galaxy in which we live. It is a spiral shaped galaxy that contains several hundred billion stars, including our Sun. It is about 100,000 light-years across and about 10,000 light-years thick. If you are at a place which has a very dark night sky, you can sometimes see the Milky Way as a thick band of stars in the sky. We live out in the suburbs of the Milky Way - not near the center, but not near the edge either.

Our Solar System
There are many planetary systems like ours in the universe, with planets orbiting a host star. Our planetary system is named the "solar" system because our Sun is named Sol, after the Latin word for Sun, "solis," and anything related to the Sun we call "solar."
Our solar system consists of our star, the Sun, and everything bound to
it by gravity — the planets Mercury, Venus, Earth, Mars, Jupiter,
Saturn, Uranus and Neptune, dwarf planets such as Pluto, dozens of moons
and millions of asteroids, comets and meteoroids.
Beyond our own solar system, we have discovered thousands of planetary
systems orbiting other stars in the Milky Way.
