The Universe contains billions of galaxies.
A galaxy is a huge collection of gas, dust, and billions of stars and
their solar systems, all held together by gravity.
​Our solar system is part of the Milky Way galaxy which is shown in this photo.


The arrow points to the location of our solar system in the Milky Way.
Our solar system is just a very small dot in this illustration of the Milky Way.
It takes light from the Sun 8.3 minutes to reach our planet but it takes that
same light more than 100,000 years to travel from one side of the Milky Way
to the other. That’s approximately 587,458,915,000,000,000 miles!
