What is a light year?
A light year is the distance light travels in one year: approximately 9.461 trillion kilometers or 5.879 trillion miles. It's used to measure vast cosmic distances. The nearest star to Earth (Proxima Centauri) is about 4.24 light years away.
What is the difference between a parsec and a light year?
A parsec (3.26 light years) is based on stellar parallax measurement—the distance at which 1 AU subtends 1 arcsecond. Astronomers prefer parsecs for precision; light years are more intuitive for the public.
How far is one Astronomical Unit (AU)?
One AU is the average distance from Earth to the Sun: exactly 149,597,870.7 kilometers or about 93 million miles. Mars is about 1.5 AU from the Sun; Jupiter is about 5.2 AU.
