In the Galaxy (milky way)that we are in there are around 100,000,000,000 (100 Billion) planets and the same amount of stars
and in the known universe there are 200,000,000,000 galaxies
try and work dat oot
So think about it like this. You are familiar with our solar system, where there
are just eight planets and one star.
Our solar system alone is billion miles wide. If you got on a jet and flew at 600 miles per hour across the solar
system, it would take roughly 1,000 years.
Our solar system is just one of 100 billion of star systems in the Milky Way galaxy.
And the Milky Way galaxy is just one of 200 billion of galaxies in the universe.
