HIP 100963 is a star in the faint northern constellation of Vulpecula.〔 It has an apparent visual magnitude of approximately 7.1,〔 making it generally too faint to be seen with the naked eye in most circumstances. The distance to this star, as determined using parallax measurements from the Hipparcos mission, is around .〔
This star has a stellar classification of G5,〔 making it a G-type star with an undetermined luminosity class. It has similar mass, temperature and chemical abundance to the Sun and was called a solar twin in a 2009 study, although its lithium abundance is three to four times that of the Sun. This lithium excess suggests that the star has a younger age of between 2.01 and 3.80 billion years, compared to the previous estimate of from a 2007 study.〔
