Difference between Light-year and Open cluster

Light-year vs. Open cluster

The light-year is a unit of length used to express astronomical distances and measures about 9.5 trillion kilometres or 5.9 trillion miles. An open cluster is a group of up to a few thousand stars that were formed from the same giant molecular cloud and have roughly the same age.

Similarities between Light-year and Open cluster

Light-year and Open cluster have 11 things in common (in Unionpedia): Astrometry, Astronomical unit, Earth, Galactic Center, Globular cluster, Large Magellanic Cloud, Milky Way, Parallax, Parsec, Spiral galaxy, Star.


Astrometry is the branch of astronomy that involves precise measurements of the positions and movements of stars and other celestial bodies.
