![]() Symbols, abbreviations, or full names for units of length,Īrea, mass, pressure, and other types. The formula used in parsecs to million light years conversion is 1 Parsec 3.26156377716744E-06 Million Light Year. The parsec was named from the abbreviations of a par allax of one arc sec ond. You can find metric conversion tables for SI units, as wellĪs English units, currency, and other data. It stands for "parallax of one arc second", and is approximately 19,131,554,073,600 (19 trillion) miles.Ĭonversion calculator for all types of measurement units. A parsec is equivalent to 3.26 light years, and since a light year is the distance light travels in 1 year 9.4 trillion km, 1 parsec equals 30.8 trillion km. The most common are the light year and the parsec. The parsec (symbol pc) is a unit of length used in astronomy. Because the distances to stars are so large, it is useful to introduce some large units of distance measure. Measuring Masses: One a.m.u.: It is defined as 1/12 th of the mass of one atom. More specifically, a light year is defined as the distance that a photon would travel, in free space and infinitely far away from any gravitational or magnetic fields, in one Julian year (365.25 days of 86400 seconds each). A light-year (ly), parsec (pc) are used to measure the distance between stars and the astronomical unit is used to measure the distance between planets. Parsec to light-year, or enter any two units below: Enter two units to convert From:Ī light year, abbreviated ly, is the distance light travels in one year: roughly 9.46 × 1012 kilometres (9.46 petametres, or about 5.88 × 1012 (nearly six trillion) miles). This takes us back to our measurements using parallax. The parsec is defined as the distance to an object with a parallax angle of 1 arcsecond. To learn more, see the privacy policy.You can do the reverse unit conversion from Light-Year Measurement Astronomers also employ other types of measurements, specifically the parsec (pc). Please note that Related Words uses third party scripts (such as Google Analytics and advertisements) which use cookies. a The parsec unit is obtained by the use of parallax and trigonometry, and is. ![]() 30.9 trillion kilometres (19.2 trillion miles ). The next closest star to us is about 4. 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. This means that we always see the Sun as it was about 8.3 minutes ago. Special thanks to the contributors of the open-source code that was used to bring you this list of term themed words: Concept Net, WordNet, and is still lots of work to be done to get this to give consistently good results, but I think it's at the stage where it could be useful to people, which is why I released it. So, the Suns light takes about 8.3 minutes to reach us. You will probably get some weird results every now and then - that's just the nature of the engine in its current state. Definition of parsec : 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. related words - rather than just direct synonyms.Īs well as finding words related to other words, you can enter phrases and it should give you related words and phrases, so long as the phrase/sentence you entered isn't too long. These algorithms, and several more, are what allows Related Words to give you. Another algorithm crawls through Concept Net to find words which have some meaningful relationship with your query. The vectors of the words in your query are compared to a huge database of of pre-computed vectors to find similar words. A parsec, equal to 3. One parsec per 3.26 years is the same as. Although the light year is a commonly used unit, astronomers prefer a different unit called the parsec (pc). ![]() One such algorithm uses word embedding to convert words into many dimensional vectors which represent their meanings. One light year is the distance light travels in one year, so it would take light 3.26 years to travel one parsec. Related Words runs on several different algorithms which compete to get their results higher in the list.
