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. 2019 A parsec is a unit of distance, not time, so why would Solo use it to explain how quickly his ship could travel? - Kyle Hill, WIRED, 12 Feb. Zeeya Merali, Scientific American, 5 Sep. 2019 The image shows the supermassive black hole at the centre of the galaxy Messier 87, which lies around 17 parsecs (55 million light years) from Earth. 2020 In this new version, Greedo pulls the trigger first in a wild shot, missing Han by half a parsec. One parsec is approximately equal to 210,000 astronomical units and equals about 3.3 light-years where the light-year is the distance travelled by the light in a year. Nola Taylor Redd, Scientific American, 10 Feb. The parsec is defined as a unit of length or distance which is used to measure the large distances to astronomical objects outside the solar system. One parsec equals 3.2616 light years, 206 265 astronomical units, or 30.857 × 1012 km. In other words, it is the distance at which one astronomical unit subtends an angle of one second of arc. 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. (pc) A basic unit of stellar distance, corresponding to a trigonometric parallax of one second of arc (1). 2021 Recently astronomers settled on a value of 25 parsecs (82 light-years) above the plane, but our results strongly disagree with this estimate. This was determined in your financial planning process and can always be revisited if you have a change in your financial circumstances. economic reintegration support project (PARSEC) as described in this appraisal. 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 Allocation by Asset Class circle graph gives you a breakdown of your asset allocation, reflecting how much equity compared to bonds/fixed income you have in the account. Table 4.1 : Breakdown by province of ex-combatants to be reintegrated. Recent Examples on the Web The clustered filaments are especially compelling as they are regularly spaced from each other, with roughly one parsec between them.
