K2-136
K2-136 is a K-type main-sequence star located in the zodiac constellation Taurus. It is a member of the Hyades open cluster, which provides a well-constrained young age on the system. The star is known to host three transiting exoplanets, discovered in 2017 from lightcurves gathered by the Kepler space telescope during the K2 extension mission. The innermost planet is approximately Earth-sized, the first such planet found in a young open cluster. The star is likely accompanied by a faint red dwarf of spectral type M7/8V located at a projected separation of . Observational history K2-136 was identified as a high- proper-motion star during the Luyten Palomar Survey in the 1970s and was included in the Luyten-Palomar proper motion catalogue, where it received the designation LP 358348. Its possible membership in the Hyades based on its proper motion was pointed out by Natalia M. Artyukhina and Pavel N. Kholopov who published a catalog of proper motions of stars i ...

Hyades (star Cluster)
The Hyades (; Greek Ὑάδες, also known as Caldwell 41, Collinder 50, or Melotte 25) is the nearest open cluster and one of the best-studied star clusters. Located about away from the Sun, it consists of a roughly spherical group of hundreds of stars sharing the same age, place of origin, chemical characteristics, and motion through space. From the perspective of observers on Earth, the Hyades Cluster appears in the constellation Taurus, where its brightest stars form a "V" shape along with the still-brighter Aldebaran. However, Aldebaran is unrelated to the Hyades, as it is located much closer to Earth (65 light-years) and merely happens to lie along the same line of sight. The five brightest member stars of the Hyades have consumed the hydrogen fuel at their cores and have evolved into giant stars. Four of these stars, with Bayer designations Gamma, Delta1, Epsilon, and Theta2 Tauri, form an asterism that is traditionally identified as the head of Taurus the Bull. The f ...
