The exoplanet orbits the star 51 Pegasi, which is about 50 light years away from Earth. Entdeckung. De allereerste exoplaneet ooit ontdekt was een planeet met een baan om de pulsar PSR 1257 en werd in 1992 ontdekt. It moves around 51 Pegasi at an average distance of only 0.05 AUs (a semi-major axis well within Mercury's orbital distance) in a highly circular orbit (e=0.03) that takes only 4.2 days to complete. It is in a class of planets called Hot Jupiters. Den 51 Pegasi b (inoffiziell och: Bellerophon genannt) ass een Exoplanéit, deen de sonnenähnleche Stär 51 Pegasi am Stärebild Pegasus ëmkreest. (Phys.org)—Astronomers have detected the presence of water molecules in the atmosphere of a nearby hot Jupiter exoplanet known as 51 Pegasi b (51 Peb b for short). Therefore, we highly encourage you to stay at your host institution during … A terrestrial planet orbiting 51 Pegasi at around the center of the calculated habitable zone would have an average orbital distance of about 1.6 AU, just beyond the orbit of Mars in the Solar System. 51 Pegasi b (saīsinājumā 51 Peg b; latviešu: Pegazs 51 b), sākotnēji nosaukts par Bellerefonu (Bellerephon) un vēlāk pazīstams arī kā Dimidijs (Dimidium), ir citplanēta, kas atrodas orbītā ap zvaigzni 51 Pegasi aptuveni 50 gaismas gadu attālumā Pegaza zvaigznājā. 51 Pegasi B. 51 Pegasi-B is a planet located in the 51 Pegasi system on the fringes of UNSC-controlled space, and is close to 85 Pegasi-194A. 51 Pegasi b (afgekort 51 Peg b), officieel Dimidium genoemd en onofficieel Bellerophon is een exoplaneet op ongeveer 50 lichtjaar van de aarde verwijderd in het sterrenbeeld Pegasus. One of the best-known hot Jupiters is 51 Pegasi b. Together with Didier Queloz in 1995, he discovered 51 Pegasi b, the first extrasolar planet orbiting a sun-like star, 51 Pegasi. Ova stranica je posljednji put izmijenjena na datum 29 januar 2020 u 17:59. In January 1995 Queloz and Mayor detected a planet, 51 Pegasi b, with a mass about half that of Jupiter and a period of 4.23 days, which they confirmed and announced later that year. The constellations that we see today will be different than they were 50,000 years ago or 50,000 years from now. 51 Pegasi B is red, Jupiter has orange and white bands, Earth is blue. The 51 Pegasi b Fellowship has forged a partnership with your host institution to ensure a rich experience by establishing access to faculty mentors and other resources to excel in your research endeavors. This year we celebrate the discovery of 51 Pegasi b in October, 1995. 51 Pegasi (abbreviated 51 Peg), formally named Helvetios / h ɛ l ˈ v iː ʃ i ə s /, is a Sun-like star located 50.45 light-years (15.47 parsecs) from Earth in the constellation of Pegasus.It was the first main-sequence star found to have an exoplanet (designated 51 Pegasi b, officially named Dimidium, formerly unofficially dubbed Bellerophon) orbiting it. 51 Pegasi b was the first, but now we know thousands of exoplanets. Laŭ la oficiala nomenklaturo, ĝi prenis la minusklan literon 'b' por indiki ke estis la unua planedo malkovrita ĉirkaŭ sia stelo.Ĉiuj la ekstersunsistemaj planedoj prenas minusklan literon, male al stel-kunuloj, kiuj prenas majusklan literon. 51 Pegasi b, abbreviated 51 Peg b, unofficially dubbed "Bellerophon", later named "Dimidium", is an extrasolar planet approximately 50 light-years away from Earth in the constellation of Pegasus. In 1995, scientists discovered 51 Pegasi b, forever changing the way we see the universe and our place in it. The time it will take to travel to this star is dependent on how fast you are going. Observations of the star 51 Pegasi began that September. 51 Pegasi b numită oficial Bellerophon este o exoplanetă care se rotește în jurul stelei 51 Pegasi din Constelația Pegas. 51 Pegasi b was the first planet to be discovered orbiting a main-sequence star, the Sun-like 51 Pegasi, and marked a breakthrough in 51 Pegasi is a star that is like our Sun and can be found 15.4 parsecs (50.1 light-years) away from the Earth in the constellation Pegasus. Still, this new planet, called 51 Pegasi b, was a surprise.A big one! It was the first Sun-like star, other than the Sun, found to have a planet orbiting it, this discovery was first made public in 1995.. 51 Pegasi b estis la unua planedo malkovrita ĉirkaŭ Sun-simila stelo kaj estas tipa ekzemplo de varma Jupitero. This artist’s view shows the hot Jupiter exoplanet 51 Pegasi b, sometimes referred to as Bellerophon, which orbits a star about 50 light-years from Earth in the northern constellation of Pegasus (The Winged Horse). In the 25 years since that discovery, we’ve found 4057 exoplanets, and that number keeps rising (you can check the most up-to-date count on the NASA Exoplanet Archive). 51 Pegasi (abbreviated 51 Peg), formally named Helvetios / h ɛ l ˈ v iː ʃ i ə s /, is a Sun-like star located 50.45 light-years (15.47 parsecs) from Earth in the constellation of Pegasus. 51 Pegasi b, abbreviated 51 Peg b, unofficially dubbed "Bellerophon", later named "Dimidium", is an extrasolar planet approximately 50 light-years away from Earth in the constellation of Pegasus. The exoplanet's discovery was made public on October 6, 1995 by Michel Mayor and Didier Queloz. 51 Pegasi b is the first Jupiter-mass planet discovered around a sun-like star. Its orbital period would be about 2.0 years.  Nomo. Planet "b" has at least 46 percent of Jupiter's mass. 51 Pegasi b (abbreviated 51 Peg b), sometimes unofficially named Bellerophon, is an extrasolar planet approximately 50 light-years away in the constellation of Pegasus. Artist's comparison of the size of the planet 51 Pegasi B (at lower right) with its star, 51 Pegasi (at upper left), and the planets of Jupiter and Earth (at lower right). Since then, we’ve figured out it’s likely a Jupiter that formed farther away from 51 Pegasi and migrated inwards towards the star, for one reason or another. LOCATION. 51 Pegasi b was the first planet to be discovered orbiting a main-sequence star, the Sun-like 51 Pegasi, and marked a breakthrough in astronomical research. 51 Pegasi b (abbreviated 51 Peg b), sometimes though unofficially named Bellerophon, is an extrasolar planet approximately 50 light-years away in the constellation of Pegasus. Between the clear evidence and the fact that 51 Peg b orbits a star like our own Sun, the hunt for more exoplanets was on. 51 Pegasi b is het prototype van de Hete Jupiter-klasse van planeten.

It is 50 light years away in the direction of the constellation Pegasus..
