Selvom 51 Pegasi b hverken er et mundret navn eller en på nogen måde en beboelig planet, så blev den ved sin opdagelse i 1995 startskuddet på en vild og vanvittig jagt på exoplaneter (planeter, som kredser om en stjerne uden for vores solsystem).

In 1995, Michel Mayor and Didier Queloz announced they discovered 51 Pegasi b, the first planet ever found around a star other than the Sun. Description. This discovery turned out to be a milestone of recent astronomy, as it opened up a new field of research that is growing impressively these days. In 1995, scientists discovered 51 Pegasi b, forever changing the way we see the universe and our place in it. The original NASA images have been converted from CMYK to RGB and slightly corrected for colour and tone in order to print at the very highest quality. Buy 51 Pegasi b: Journal with Cover Art by NASA (Retro Space Travel Poster Cover Art by NASA) (Volume 10) on Amazon.com FREE SHIPPING on qualified orders The exoplanet is about half the mass of Jupiter, with a seemingly impossible, star-hugging orbit of only 4.2 Earth days. Humanity took one step closer to answering these questions in October 1995 when it was announced that the star 51 Pegasi harbors at least one planet. 51 Pegasi b, the first extrasolar planet confirmed to orbit a sunlike star.The planet orbits a fifth-magnitude star, 51 Pegasi, located 48 light-years away from Earth in the constellation Pegasus. 51 Pegasi b was the first of many exoplanets to be discovered that orbits a star like that of our Sun. This year we celebrate the discovery of 51 Pegasi b in October, 1995. '51 Peg' helped launch a whole new field of exploration. This giant planet is about half the size of Jupiter and orbits its star in about four days. Deadline: September 20th These are not run-of-the-mill posters! In the above picture of 51 Peg the planet is not visible - it can only be detected by noticing small changes in the star's motion. Our reproductions of NASA’s Visions of the Future: 51 Pegasi b are available on museum quality photographic paper, printed with archival inks. In this poster, I will present new precision radial velocities that we collected for the 51 Pegasi b system and provide a mass limit of putative planets that may remain undetected on dynamically stable orbits either interior or exterior to the orbit of 51 Pegasi b. There is debate over which exoplanet was discovered is considered the "first," one stands out from the rest. The exoplanet is about half the mass of Jupiter, with a … 51 Pegasi b / #10.
