This calculator allows you to convert from Light year to Parsec and in a reverse direction. To convert from Light year to Parsec, enter the amount of Light year into the first input and to convert from Parsec to Light year, enter the amount of Parsec into the second input.
20 Light year = 6.1320278761306 Parsec
Light year to Meter | Light year to Foot | Light year to Centimeter | Light year to Inch | Light year to Kilometer | Light year to Mile | Light year to Millimeter | Light year to Yard | Light year to Micrometer |20 Light year equal 6.1320278761306 Parsec.
Every 1 Light year = 0.30660139380653 Parsec and so, 20 Light year = 20 multiplied by 0.30660139380653 = 6.1320278761306 Parsec.
What is "parsec"?
In the space scale, distances can't be expressed by meters or feet. Professional astronomers use the parsec unit to express these incredible distances. The parsec is a unit for expressing distances between stars and galaxies. One parsec equals 3.26 light-years, which is equivalent to 3.09 × 1013 km.
Parsec has a special way to measure distance, it depends on trigonometry. It is defined as the distance at which one astronomical unit subtends an angle of one arcsecond.
The parsec distance of an object is the reciprocal of its parallax in seconds of arc.
It is amazing to know that when we look at the night sky, we can see stars which are nearly a distance of 500 parsecs of the Sun.
There is a star is called Proxima Centauri. It exists within another solar system called Alpha Centauri triple-star system. It has a parallax of 0.769 second of arc which means it is 1.30 parsec far from us.
