uranologist are calling Kepler-432b a ‘ maverick ’ planet because everything about this newly found exoplanet is an extreme , and is unlike anything we ’ve found before .
This is a giant , dim planet orbiting a carmine giant lead , and the planet has enormous temperature swing throughout its year . In summation to all these extremes , there ’s another reason you would n’t want to live on Kepler 432b : its days are numbered .
“ In less than 200 million years , Kepler-432b will be swallowed by its continually expanding legion principal , ” said Mauricio Ortiz , a PhD student at Heidelberg University who head one of the two studies of the planet . “ This might be the reason why we do not find other planets like Kepler-432b – astronomically speak , their lives are extremely short . ”
Kepler-432b is one of the densest and massive planets ever find . The planet has six time the mint of Jupiter , but is about the same size . The bod and the size of its ambit are also strange , as the orbit is very pocket-size ( 52 Earth mean solar day ) and extremely elongated . The elliptical orbit brings Kepler-432b both unbelievably close and very far by from its host star .
“ During the winter season , the temperature on Kepler-432b is rough 500 degrees Anders Celsius , ” said Dr. Sabine Reffert from the Königstuhl lookout , which is part of the Centre for Astronomy . “ In the light summertime time of year , it can increase to nigh 1,000 arcdegree Anders Celsius . ”
Dr. Davide Gandolfi , also from the Königstuhl observatory , said that the star topology Kepler-432b is orbiting has already exhaust the nuclear fuel in its core and is step by step elaborate . Its radius is already four time that of our Sun and it will get even larger in the future tense .
While Kepler-432b was antecedently identified as a transit major planet candidate by the NASA Kepler satellite delegacy , two research groups of Heidelberg astronomer severally made further watching of this rare major planet , acquiring the high - preciseness measurement need to determine the planet ’s mass . Both groups of researchers used the 2.2 - metre telescope at Calar Alto Observatory in Andalucía , Spain to call for data point . The group from the United States Department of State lookout also observe Kepler-432b with the Nordic Optical Telescope on La Palma ( Canary Islands ) .
The results of this research were publish inAstronomy & Astrophysics .
