Solar analog

From Wikipedia, the free encyclopedia

Solar analog (or more informally a solar twin) is the name for a star with characteristics similar to our own Sun. Most scientists consider the prospect of having habitable planets is greater for solar twins than other stars.

A solar analog is a star with properties such as spectral type, surface temperature, rotational velocity, mass, variability and metallicity which are close to the solar values. Observations of solar analogs are important for understanding better the properties of our own Sun in relation to other stars and the habitability of planets.

Stars currently considered to be solar analogs include:
