Background

Nowadays, almost everyone knows that:

The Earth is a planet that belongs to a Solar System - a system of linked celestial bodies revolving around the Sun (the source of energy for the entire system), which is a common star. The Sun looks much brighter than other stars just because it is closer to us. Other components of the solar system include: planets, natural satellites, asteroids, comets and meteors.

The Sun on the other hand, belongs to a system of billions of linked stars (and all the other celestial bodies linked to each individual star). Such a system is known as a "galaxy". Our solar system is a tiny part of this gigantic system where the galaxy we belong to is known as the Milky Way. All galaxies together form the Universe.
