A parsec is the distance 3.26 light-years that a star must lie from the Sun for its parallax angle to be exactly 1 arcsecond (1/3600 of a degree). A Megaparsec is 1,000,000 (Million) Parsecs.A Kiloparsec is 1,000 (Thousand) parsecs.An Astronomical Unit is the distance between the Earth and the Sun. The numbers have been rounded up to 1d.p. There are roughly 206,263.4 Astronomical Units in a Parsec. Divide Parsecs by 3.26163344 to give Light Years.Divide one by the previous answer to give the Parsecs.Divide by 1000 to give the Milliarcseconds.This result is a very useful tool in astronomy for calculating the distance between the earth and far away stars. The star has a distance of about 1.3 Parsecs based on the 2007 Hipparcos catalogue.įor any given parallax, e.g. That is the parallax effect a change in the apparent position of an object due to a change in the position of observation point. The nearest object is the star Proxima Centauri, the second nearest star to Earth after the Sun. Nothing in space is at a distance of 1 Parallax from the Earth. An object with a parallax of 1 is 1 Parsec away. From the parallax, you can then calculate the distance. The shift in location is referred to as the parallax. If you look at an object in the distance, then close one eye and then the other, the object will seem to shift slightly. When objects are measured in space, they are measured by the shift in parallax. In Layman's Terms, hopefully, when measuring the parallax shift of an object in space, the shift is equivalent to 1. Parsec has a special way to measure distance, it depends on trigonometry. A Parsec represents the distance in space at which the Earth's orbit subtends an angle of one second of arc. One parsec equals 3.26 light-years, which is equivalent to 3.09 × 1013 km. So, what is a Parsec?Ī Parsec is a unit of distance. To get out of the nebula and to Savareen to convert the Coaxium ore before the Coaxium explodes, Han Solo plots the shortest but dangerous way out of the nebula which happens to be 12 parsecs thereby clearing up the 12 Parsecs mistake of the first film. The planet Kessel is deep within a nebula and contains large reserves of Coaxium ore which Han and his friends need. Solo - A Star Wars Anthology film tries to clear up what a parsec is and how the term was used.
