New Gigantic Exoplanets Discovered With Orbits of 15-40 Years


Jupiter Sized Exoplanet


Over 4000 exoplanets have been discovered since the first one in 1995, but the vast majority of them orbit their stars with relatively short periods of revolution. But five new planets have been discovered with periods of revolution between 15.6 and 40.4 years, with masses ranging approximately from 3 to 27 times that of Jupiter. A new study using the EULER telescope at the La Silla Observatory in Chile increases the list of 26 planets with a rotation period greater than 15 years.
