This exoplanet system is called TRAPPIST-1, named for The Transiting Planets and Planetesimals Small Telescope (TRAPPIST) in Chile.
First Exoplanet Discovered 6 October 1995 On this day in 1995, two Swiss astronomers discovered 51 Pegasi, the first major star apart from the Sun to have a planet orbiting it, a … In May 2016, researchers using TRAPPIST announced they had discovered three planets in the system.
This groundbreaking find in 1995 confirmed planets like Earth could exist elsewhere in the universe.
In 1992, astronomers discovered the first exoplanet, or planet outside our solar system. When Was the First Exoplanet Discovered? The answer to the question, “When was the first exoplanet discovered?” is actually quite complex. But it didn’t come in any form they’d really anticipated. Finding this fast-moving giant, known as 51 Pegasi b, kicked off what might be called the “classical” period of planet hunting. Using NASA's Kepler Space Telescope, astronomers have discovered the first Earth-size planet orbiting a star in the "habitable zone" -- the range of distance from a star where liquid water might pool on the surface of an orbiting planet. 51 Pegasi b, also called "Dimidium," was the first exoplanet discovered orbiting a star like our sun.
While there is much debate over which exoplanet discovery is considered the "first," one stands out from the rest.
The problem is that detections of exoplanets have been claimed on various occassions, and usually those claims have subsequently been disproven. The exoplanet is about half the mass of Jupiter, with a seemingly impossible, star-hugging orbit of only 4.2 Earth days.
In 1995, scientists discovered 51 Pegasi b, forever changing the way we see the universe and our place in it. First convincing exoplanet discovered around a Sun-like star. While the minimum mass of …
