Any opinions expressed in the examples do not represent those of Merriam-Webster or its editors. 2020 In this new version, Greedo pulls the trigger first in a wild shot, missing Han by half a parsec. Nola Taylor Redd, Scientific American, 10 Feb. As the Earth orbits the sun, the apparent position of a (relatively) nearby star varies with relation to a. 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. It is exactly 648,000/ astronomical units, or approximately 30.9 trillion kilometers. ![]() A parsec is a unit of distance used in astronomy. Earth circles the Sun, making one complete orbit per year. 2021 Recently astronomers settled on a value of 25 parsecs (82 light-years) above the plane, but our results strongly disagree with this estimate. How many kilometers are in a parsec Easy pc to km conversion. Launie Wellman Festus, Missouri Answer: A parsec, or parallax second, is defined as 3.26 light-years because of how it is measured. 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. A parsec is a unit of distance that is often used by astronomers as an alternative to the light-year, just as kilometers can be used as an alternative to miles. Levy, Wired, The clustered filaments are especially compelling as they are regularly spaced from each other, with roughly one parsec between them. 30.9 trillion kilometres (19.2 trillion miles ). 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. 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. 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. ![]()
