21 Apr 2015, 22:00 UTC <span style="font-family: inherit;">L. Mancini et al. (2015) report on the discovery of KOI-372, a planetary system consisting of two giant planets on wide and eccentric orbits around a Sun-like star. The two giant planets are identified as KOI-372 b and KOI-372 c, with the suffixes “b” and “c” indicating their planetary nature. KOI-372 b is a transiting giant planet that was first detected by NASA’s Kepler space telescope. Follow-up radial velocity measurements were then made using a ground-based telescope to determine the mass of KOI-372 b. The radial velocity measurements and observations by Kepler indicate that KOI-372 b is a dense Jupiter-like planet with 3.25 ± 0.20 times the mass and 0.882 ± 0.088 times the diameter of Jupiter.</span><br /><div style="text-align: center;"><span style="font-family: inherit;"><br /></span></div><div class="separator" style="clear: both; text-align: center;"><a href="http://4.bp.blogspot.com/-X0eKPZ7NOEE/VTXIz2gP4AI/AAAAAAAAHUQ/F-uoBr4KVVw/s1600/Post%2B-%2BApril%2B2015%2B(11)%2B-%2B1.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="390" src="http://4.bp.blogspot.com/-X0eKPZ7NOEE/VTXIz2gP4AI/AAAAAAAAHUQ/F-uoBr4KVVw/s1600/Post%2B-%2BApril%2B2015%2B(11)%2B-%2B1.jpg" width="640" /></a></div><div style="text-align: center;"><span style="font-family: inherit;">Figure 1: Artist’s impression of a giant planet with a hypothetical moon in orbit around it.</span></div><span style="font-family: inherit;"><br /></span><span style="font-family: inherit;">KOI-372 b orbits its host star every 125.6 days in a fairly elongated orbit. The orbit of KOI-372 b brings the planet as close as 61 million km (0.41 AU) from its host star and out as ...
