What is a Exoplanet?
An exoplanet or extrasolar planet is any planet detected beyond our solar system. Exoplanets orbit around other stars and are very hard to see directly with telescopes. They are hidden by the bright glare of the stars they orbit.
So, astronomers use other ways to detect and study these distant planets. They search for exoplanets by looking at the effects these planets have on the stars they orbit. More than 4,000 exoplanets are known, and about 6,000 await further confirmation.
