It is about {{convert|184|ly|pc|abbr=off|lk=on}} away from Earth, with an apparent magnitude of 8.76. It was identified in November 2018 as a potential solar sibling to the Sun. It is very similar to the Sun; the Sun is a G2V star. Similar by spectrum and size, it may have formed in the same stellar nursery as the Sun 4.57 billion years ago.[1] See also
