The closest encounter to the Sun so far predicted is the low-mass orange dwarf star Gliese 710 / HIP 89825 with roughly 60% the mass of the Sun. [4] It is currently predicted to pass 0.1696 ± 0.0065 ly (10 635 ± 500 au) from the Sun in 1.290 ± 0.04 million years from the present, close enough to significantly disturb the Solar System's Oort ...

This was the first star other than the Sun to have its distance measured. [220] [222] [223] Uranus: Planet of the Solar System 1781 − 1838 18 AU: This was the last planet discovered before the first successful measurement of stellar parallax. It had been determined that the stars were much farther away than the planets. Saturn: Planet of the ...
Such multiple star systems are indicated by parentheses showing the individual magnitudes of component stars bright enough to make a detectable contribution. For example, the binary star system Alpha Centauri has the total or combined magnitude of −0.27, while its two component stars have magnitudes of +0.01 and +1.33. [3]
