HD 211415
HD 211415 is a double star in the constellation Grus. It has a relatively high proper motion and is located about 45 light years from the Sun.
As of 1994, the two members of this system have an angular separation of 0.778″ along a position angle of 145.9°. This corresponds to an estimated semimajor axis of 57.75 AU.〔 This is larger than the orbit of Pluto around our Sun, which has a semi-major axis of 39.5 AU. This system has not been observed for a sufficient length of time to establish the remaining orbital parameters with sufficient precision.
==Possibility of planets and life==
HD 211415 was identified in September 2003 by astrobiologist Margaret Turnbull from the University of Arizona in Tucson as one of the most promising nearby candidates for hosting life based on her analysis of the HabCat list of stars.〔
