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 confirmed detection of an exoplanet was in 1992 around a pulsar, and the first detection around a main-sequence star was in 1995. A different planet, first detected ...
A disintegrating planet with a comet-like tail. [1] GJ 2126 b 1.3 +0.2 ... List of extrasolar planetary collisions; Lists of exoplanets by year of discovery
As of January 2010, this is the lightest known extrasolar planet to orbit a main-sequence star. [12] 30 planets: On October 19, it was announced that 30 new planets were discovered, all were detected by the radial velocity method. It is the most planets ever announced in a single day during the exoplanet era [clarification needed]. October 2009 ...
51 Pegasi b, officially named Dimidium / d ɪ ˈ m ɪ d i ə m /, is an extrasolar planet approximately 50 light-years (15 parsecs) away in the constellation of Pegasus.It was the first exoplanet to be discovered orbiting a main-sequence star, [3] the Sun-like 51 Pegasi, and marked a breakthrough in astronomical research.
In addition to detecting planets itself, Kepler has also uncovered the properties of three previously known extrasolar planets. Public Kepler data has also been used by groups independent of NASA, such as the Planet Hunters citizen-science project, to detect several planets orbiting stars collectively known as Kepler Objects of Interest.
The main catalogue comprises databases of all of the currently confirmed extrasolar planets as well as a database of unconfirmed planet detections. The databases are frequently updated with new data from peer-reviewed publications and conferences.
Kepler-452b (sometimes quoted to be an Earth 2.0 or Earth's Cousin [4] [5] based on its characteristics; also known by its Kepler object of interest designation KOI-7016.01) is a candidate [6] [7] super-Earth exoplanet orbiting within the inner edge of the habitable zone of the sun-like star Kepler-452 and is the only planet in the system discovered by the Kepler space telescope.
SPECULOOS-3 b is an Earth-sized exoplanet, orbiting the ultracool red dwarf star SPECULOOS-3.It is relatively close to Earth, at a distance of 55 light-years. [4] SPECULOOS-3 b takes only about 17 hours to complete an orbit around SPECULOOS-3, and, because of that proximity, it receives very high levels of radiation and is tidally locked, meaning that one side of the planet always faces its ...
