This yellow star is about to stop thermonuclear hydrogen-fusion in its core and eventually expand to become a red giant. Planetary systemIn July 2007, the star is found to have a giant planet in orbit around it.[13] It has minimum mass two and a half times that of Jupiter and orbits the star closer than Mercury to the Sun. {{orbitbox planet begin| table_ref = [14] }}{{orbitbox planet | exoplanet = b | mass = {{val|2.55|0.34|p=≥}} | semimajor = {{val|0.238|0.015}} | period = {{val|36.9987|0.0011}} | eccentricity = {{val|0.0796|0.0067}} }}{{orbitbox end}} See also
