What is the closest planet outside of our solar system?

It would be the exoplanet which is orbiting the star Proxima Centauri. In August, 2016, astronomers confirmed the discovery of an exoplanet orbiting within the habitable reaches of Proxima Centauri, the closest star to Earth and part of the small star system; Alpha Centauri- a triple star system just over 4 light years away. Its believed to have a mass of 1.3 of Earth-

List of potentially habitable exoplanets

The following list includes some of the potentially habitable exoplanets discovered so far. It is mostly based on estimates of habitability by the Habitable Worlds Catalog (HWC), and data from the NASA Exoplanet Archive.The HWC is maintained by the Planetary Habitability Laboratory at the University of Puerto Rico at Arecibo.

Exoplanets

Overview Most of the exoplanets discovered so far are in a relatively small region of our galaxy, the Milky Way. ("Small" meaning within thousands of light-years of our solar system; one light-year equals 5.88 trillion miles, or 9.46 trillion kilometers.) Even the closest known exoplanet to Earth, Proxima Centauri b, is still about 4 light-years []

Astronomers Reveal Presence of a Planet Orbiting Our Solar System

Using the European Southern Observatory''s Very Large Telescope (ESO''s VLT), astronomers have detected a planet orbiting our solar system''s closest single star. Previous studies have found as many as five planets orbiting Earth''s closest stellar neighbors, a three-star system just over four light years away composed of Alpha Centauri A, Alpha Centauri B, and

Exoplanet

An exoplanet or extrasolar planet is a planet outside the Solar System. The first possible evidence of an exoplanet was noted in 1917 but was not then recognized as such. The first confirmation of the detection occurred in 1992. A different planet, first detected
