The Discovery and Interesting Facts About Exoplanets

Our universe always astonishes us.

The exoplanet is one such interesting aspect of the universe.

Let’s look at the different aspects of an Exoplanet:

Exoplanets are planets that exist outside of our solar system.

Most exoplanets orbit other stars, however rogue planets, or free-floating exoplanets, orbit the galactic center and are not bound to any star.

The Milky Way, our galaxy's smallest part, contains the vast majority of known exoplanets.

Exoplanets range in size from gas giants larger than Jupiter to small, rocky planets roughly the size of Earth or Mars.

They can be hot enough to boil metal or frozen solid.

They can orbit their stars so closely that a "year" only lasts a few days.

Exoplanets can orbit two suns at the same time.

Some exoplanets are sunless rogues, roaming the galaxy in perpetual darkness.

The first exoplanets were discovered in the 1990s.

We now live in an exoplanet universe.

The number of confirmed planets is in the thousands and growing!
