Line 47:
Near solar twins can also help answer whether the Sun is unique or not. It used to be thought that the Sun might be unique for its low lithium abundance. This star was one of two stars that were used in 2007 papers by Melendez & Ramırez<ref name=Melendez /> to show that the Sun was not unique in this respect as it has lithium abundance similar to our Sun, but is not an idea comparison as HD 133600 is 1.5 billion years older than the Sun. Yet, this has made it a useful star for studies into the problem of the depleted lithium abundance at the solar surface compared with other stars, something that is not yet fully understood, and known as the [[Standard solar model#Lithium depletion at the solar surface|Lithium depletion problem]].
