| Abstract: |
The properties of a rocky planet’s host star may be associated with the origin of life and the evolution of observers on that planet. By comparing the Sun to other stars in our Galaxy, we may be able to identify such properties. If our Sun is a typical star, stellar conditions appropriate for life, and life itself, may be common in the Universe. On the other hand, if the Sun is atypical or even unique, then the life orbiting the Sun may also be atypical or unique. Here we present the comparison between the Sun and stars for three important parameters that may be associated with the origin and evolution of life. We find that:
(i) The Sun is more massive than 95±2% of nearby stars.
(ii) The Sun is younger than 53±2% of stars in the Galactic disk.
(iii) The Sun is more metal rich than 65±2% of nearby stars. |
