HAT-P-17 is a K-type main sequence star about 92.6 parsecs (302 ly) away. It has a mass of about 0.857 ± 0.039 M☉. It is the host of two planets, HAT-P-17b and HAT-P-17c, both discovered in 2010. A search for Continue Reading
HAT-P-18 is a K-type main sequence star about 530 light-years away. The star is very old and has a concentration of heavy elements similar to solar abundance. A survey in 2015 detected very strong starspot activity in HAT-P-18. In 2010, Continue Reading
HAT-P-4b is an extrasolar planet orbiting the star BD+36º2593 more than 1,000 light-years away in the constellation Boötes. It was discovered by means of the transit method on October 21, 2007. It is the fourth planet detected by the HATNet Continue Reading
HAT-P-5b is an extrasolar planet orbiting the star HAT-P-5, more than 1,100 light-years away, in the constellation Lyra. It was discovered through the transit method in 2007. It is the fifth planet detected by the HATNet Project. The planet is Continue Reading
HAT-P-3b is an extrasolar planet that lies 457 light-years from Earth. It was discovered by the HATNet project, using the transit method. Its mass is estimated at about 0.6 times that of Jupiter, with a heavy metal center of about Continue Reading
