A light year is the distance that light will travel in one year. A parsec is short for parallax second, which is also a measure of distance.
Answer 1 Parsec = 3.26163626 light years 1 light year = 0.30659458 Parsecs

How many years is the equivalent of a parsec?

A year is a unit of time, and a parsec is a unit of length, so you can't convert between the two. If you mean light-years, then 1 Parsec = 3.26163626 light years.


What is light-year a parsec?

"Light-year" and "parsec" are two units of length used in astronomy - for distant objects. 1 parsec = 3.26 light-years. A light-year is defined as the distance that light travels in a year. A parsec is defined as the distance at which an object would have to be to have a parallax of one arc-second.


How many parsecs in a light year?

A parsec is equal to approximately 3.26 light years. So one light year would be about 0.30675 of a parsec.

What do astronomers use to measure distances between stars?

If you refer to the units, both the light-year and the parsec are often used. A light-year is the distance light travels in a year; about 9.5 x 1012 kilometers (9.5 million million kilometers). A parsec is about 3.26 light-years.


Which unit of length is a longer measure of distance 1 light year or 1 parsec?

A parsec is 3.26 light years. That's longer than 1 light year.

A parsec is the distance light travels in one year?

No. The distance light travels in a year is called a light-year. A parsec is the distance at which a star (or other object) would have a yearly parallax of 1 arc-second, and it is equal to about 3.26 light-years.

When is a parsec used?

Parsecs are used as units of measurement for the enormous distances in space. One parsec is roughly 3.3 times greater in distance than one light year. A light year is the distance light travels in one year in a vacuum.
