Difference between Light-year and Milky Way

Light-year vs. Milky Way

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. The Milky Way is the galaxy that contains our Solar System.

Similarities between Light-year and Milky Way

Light-year and Milky Way have 22 things in common (in Unionpedia): Age of the universe, Andromeda Galaxy, Astronomical unit, Black hole, Epoch (astronomy), Galactic Center, Galaxy, Galaxy cluster, Globular cluster, Great Attractor, Interstellar medium, Large Magellanic Cloud, Messier object, NASA, Parallax, Parsec, Solar System, Speed of light, Spiral galaxy, Star, Sun, Virgo Cluster.

Age of the universe

In physical cosmology, the age of the universe is the time elapsed since the Big Bang.

Andromeda Galaxy

The Andromeda Galaxy, also known as Messier 31, M31, or NGC 224, is a spiral galaxy approximately 780 kiloparsecs (2.5 million light-years) from Earth, and the nearest major galaxy to the Milky Way.

Black hole

A black hole is a region of spacetime exhibiting such strong gravitational effects that nothing—not even particles and electromagnetic radiation such as light—can escape from inside it.

Epoch (astronomy)

In astronomy, an epoch is a moment in time used as a reference point for some time-varying astronomical quantity, such as the celestial coordinates or elliptical orbital elements of a celestial body, because these are subject to perturbations and vary with time.

Galaxy cluster

A galaxy cluster, or cluster of galaxies, is a structure that consists of anywhere from hundreds to thousands of galaxies that are bound together by gravity with typical masses ranging from 1014–1015 solar masses.

Great Attractor

The Great Attractor is an apparent gravitational anomaly in intergalactic space at the center of the local Laniakea Supercluster, in which the Milky Way is located, in the so-called Zone of Avoidance that is notoriously difficult to observe in visible wavelengths due to the obscuring effects of our own galactic plane.
