You are here


Have you ever stopped to think about where you are in relation to the rest of the world? Which direction is St. Louis from here? London? Zimbabwe? Or have taken it a step further and asked: How far is it to the nearest planet?

The nearest planet to Earth is Venus, whose average distance from Earth is about 45 million kilometers or 28 million miles. The closest star to Earth is the sun which is 1 astronomical unit (AU) or almost 150,000,000 kilometers. The second closest star to Earth is Alpha Centauri, which is about 4.37 light years, or 41.34 TRILLION kilometers!

Most of the stars that we can see in the sky are part of the Milky Way galaxy, which is a group of billions of stars. As far as galaxies go, we live in a fairly large one that is about 90,000 light years across.

Okay, now let’s zoom out much wider and find out how far to our nearest galactic neighbors:
