[2] It is one of the most Sun-like stars yet known in terms of size, mass, temperature, and chemical makeup.
[6][7] It is 208 light years away in the constellation of Draco,[8] lying about halfway between Polaris and Dubhe on the celestial sphere.
HIP 56948 is among the best candidates for a solar twin because of the known possible contenders, its lithium abundance most resembles that of the Sun.
Using high-resolution, high-S/N spectra obtained at McDonald Observatory, we show that the stars HIP 56948 and HIP 73815 are very similar to the Sun in both stellar parameters and chemical composition, including a low Li abundance, which was previously thought to be peculiar in the Sun.
Considering the age of this star (~1 ± 1 Gyr older than the Sun)[Notes 1] and its location and orbit around the Galaxy, if terrestrial planets exist around it, they may have had enough time to develop complex life, making it a prime target for SETI.
