#PARSEC UNIT OF DISTANCE FULL#
You can find a full list of credits here. The terms and definitions were chosen, written and reviewed by a collective effort from the OAE, the OAE Centers and Nodes, the OAE National Astronomy Education Coordinators (NAECs) and other volunteers. The OAE Multilingual Glossary is a project of the IAU Office ofĪstronomy for Education (OAE) in collaboration with the IAU Office of Astronomy It is about 3.26 light-years, which is equal to just under 31 trillion (3.1×1013) kilometers or just over 19 trillion (1.9×1013) miles. This term and its definition is still awaiting approval The parsec (symbol: pc) is a unit of length used in astronomy.
This is because its definition is closely related to a method of measuring. If it is possible to measure an object's parallax, its distance can be directly determined. Many astronomers prefer to use parsecs (abbreviated pc) to measure distance to stars. It is not dependent upon an arbitrary time scale. Astronomers use the parsec instead of light years because the parsec is directly determined from geometry and trigonometry. A parsec is approximately equal to 3.26 light years.
Even the closest star other than our Sun has a parallax of less than 1 arcsecond. By measuring the parallax of a star astronomers can directly determine the distance to it. This gives the relationship: distance, d (in parsecs) = 1 / parallax angle, p (in arcseconds). In other words, 1 parsec is 80271944 times bigger than a earth distance from moon. The formula used in parsecs to earth distance from moons conversion is 1 Parsec 80271943.2858581 Earth Distance from Moon. pc stands for parsecs and Earth Moon Distance stands for earth distance from moons. One parsec is the distance to a point in space that subtends a parallax angle of one arcsecond. Parsecs to Earth Distance from Moons Conversion.
The parsec (pc) is a standard unit of distance measure in astronomy.
