How Many Solar Systems Are in Our Galaxy?

6 days ago· Our solar system is just one specific planetary system—a star with planets orbiting around it. Our planetary system is the only one officially called "solar system," but astronomers have discovered more than 3,200 other stars with planets orbiting them in our galaxy. That''s just how many we''ve found so far.

The nearest star system | NASA Jet Propulsion Laboratory (JPL)

Alpha Centauri is the nearest star system. Distance from Earth 4,365 al (40 000 billion kilometers. The Sun (yellow star) distance from Earth 150 000 000 km, the exoplanet distance from Alpha Centauri b (orange star) 6 000 000 km.

Two other planets known to orbit Proxima Centauri are visible in the image too: Proxima b, a planet with about the same mass as Earth that orbits the star every 11 days and is within the habitable zone, and candidate Proxima c, which is on a longer five-year orbit around the star.

Which star is closest to the Sun?

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 (10635±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 cloud.
