Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The first super-Earths were discovered by Aleksander Wolszczan and Dale Frail around the pulsar PSR B1257+12 in 1991. The two outer planets of the system have masses approximately 4 times Earth, too small to be gas giants. The first super-Earth around a main sequence star was discovered by a team under Eugenio Rivera in 2005. It orbits Gliese 876 and received the designation Gliese 876 d (two Jupiter sized gas giants had previously been discovered in that system). It has an estimated mass of 7.5 Earth masses and a very short orbital period of just about 2 days. Due to the proximity of Gliese 876 d to its host star (a red dwarf), it has a high surface temperature of up to 650 kelvins and may support liquid water.
