Qs & As - Space Questions

In Qs & As parts of this blog, I'm going to answer some questions that people ask me. These are some of the questions about 'space'. Just like this:

What is space?
Space is everything outside earth, the planet on that we live on. In space, there are many different objects, such as planets, comets, black holes and stars. Our sun is a medium-sized star in a galaxy of other billion stars. Outside our galaxy there are billions of other galaxies.

Does every single star have Planets spinning around them?
I don’t know why, but the answer is no. A star that has no planets orbiting them is not called a Sun. There is nobody that can watch then when they rise for a new day, but we can. We can see the stars around our Solar-System but that doesn’t mean that the stars around us has no planets. It is just that we can’t see the planet even if they have one. The point is: NOT ALL stars have planets.
