The measured properties of this star are very similar to those of the Sun, making it a candidate solar twin. However, it has a lower abundance of lithium than the Sun and appears over 3 billion years older, so it may instead be a solar analog. It was suggested by astronomer Olin Eggen that this star is a member of the Wolf 630 moving group of stars that share a common motion through space. The space velocity components of HD 129357 are {{nowrap|(U, V, W)}} = {{nowrap|(+21.3, −36.3, −32.0)}}.[12]References1. ^1 {{citation | title=Population Synthesis in the Blue. IV.
