Find Your Birthday Star

When you look into space, you look back in time! You see stars and other objects in space as they looked when the light left them.

For example, the Sun is 8 light-minutes (93 million miles) from Earth, which means sunlight takes 8 minutes to reach our eyes, and we always see the Sun as it looked 8 minutes ago.

Your "birthday star" is any star whose light left it around the time you were born. The starlight you see is as old as you are. Some stars listed below are too dim to see without a telescope.

Can't find a match for your age? Round up or down.

Note: Distance estimates vary for some stars; this list is adapted mostly from:
