![]() These examples are programmatically compiled from various online sources to illustrate current usage of the word 'parsec.' Any opinions expressed in the examples do not represent those of Merriam-Webster or its editors. Parsec is defined as the distance to an object with a parallax angle of 1 arcsecond. 2020 In this new version, Greedo pulls the trigger first in a wild shot, missing Han by half a parsec. The meaning of PARSEC is a unit of measure for interstellar space that is equal to 3.26 light-years and is the distance to an object having a parallax of one second as seen from points separated by one astronomical unit. Nola Taylor Redd, Scientific American, 10 Feb. 2020 The problem comes in the final parsec, where gravity is not strong enough to overcome the centrifugal force of each black hole’s orbit to pull the pair closer together. 2021 Recently astronomers settled on a value of 25 parsecs (82 light-years) above the plane, but our results strongly disagree with this estimate. 30.9 trillion kilometres (19.2 trillion miles ). Joshua Rapp Learn, Discover Magazine, What, then, can astronomers do to determine whether the final parsec problem is really a problem? - Alison Klesman, Discover Magazine, 12 July 2019 This is a huge region for comparison, ten kiloparsec is about the radius of a typical spiral galaxy like our own Milky Way, and a parsec itself is already pretty big, at more than three light-years. The parsec (symbol: pc) is a unit of length used to measure the large distances to astronomical objects outside the Solar System, approximately equal to 3.26 light-years or 206,265 astronomical units (AU), i.e. Levy, Wired, The clustered filaments are especially compelling as they are regularly spaced from each other, with roughly one parsec between them. Example: convert 15 Mpc to ly: 15 Mpc 15 × 3261563.7769443 ly 48923456.654164 ly. One parsec is the distance to an object that has a parallax angle of 1 arc. Next - we need to find out how many AUs there are in a Light-Year. ![]() Justin Ray, Robb Report, 14 June 2023 The surface of a planet within one parsec of the Milky Way’s center could reach over 5,700 kelvin, as hot as the sun’s surface, just from dark matter traffic. Example: convert 15 pc to ly: 15 pc 15 × 3.2615637769 ly 48.9234566542 ly. Recent Examples on the Web To wrap your mind around that distance, 1 parsec is equal to 3.26 light years or about 206,265 times the distance from Earth to the Sun.
