Exoplanets ['ĕx-ō-'plă-nəts]
Planets that orbit a star outside our solar system.

Every year astronomers are discovering stars other than our own sun that have planets orbiting around them. These planets are called exoplanets, or extrasolar planets. They are huge distances away from Earth, so special telescopes and methods are needed to find them. Though we may wonder how much like Earth exoplanets are, they are too far away for astronomers to see what they really look like or to determine if any life exists on them.
