-'''KIC 11026764''', nicknamed "Gemma" by Li ''et al.'',<ref name=Li2020 /> is a [[G-type star|G-type]] [[main sequence]] [[star]] whose characteristics have been extensively measured by the [[Kepler (spacecraft)|''Kepler'' spacecraft]] because of its similarity to the Sun. Its diameter is 2.18 times the Sun and is aged at 5.94 billion years, slightly older than the Sun.<ref name=Metcalfe>{{cite journal | doi=10.1088/0004-637X/723/2/1583 | title=A Precise Asteroseismic Age and Radius for the Evolved Sun-Like Star Kic 11026764 | journal=The Astrophysical Journal | volume=723 | issue=2 | pages=1583–1598 | year=2010 | last1=Metcalfe | first1=T.
