But some studies classify it as a massive (30 to 19~\mbox{M}_{\odot}) post-red supergiant evolving to become a Type II supernova. Given that One light-year is the distance light travels in one year. This distance is referred to as one light year. Proxima Centauri, the closest star to our own, is still 40,208,000,000,000 km away. [3], The light-year is most often used when expressing distances to stars and other distances on a galactic scale, especially in non-specialist contexts and popular science publications. The resulting distance is To obtain an One light-year is about 6 trillion miles (9 trillion km). 46 10 15 = Travel by spaceship to our closest intergalactic neighbor, the Canis Major Dwarf, would take almost 750,000,000 years with current technology. Last year, astronomers raised the possibility that our nearest neighbor, Proxima Centauri, has several potentially habitable exoplanets that could fit the bill. May be this questing is old, but if some one looking for the answer, for people that don't know much about scientific calculation they are often co Written by band members James Hetfield and Lars Ulrich, the song portrays a World War I soldier who is severely woundedarms, legs and jaw blown off by a landmine, blind and unable to speak or movebegging God to take his life. [21] Ule explained the oddity of a distance unit name ending in "year" by comparing it to a walking hour (Wegstunde). It is the total distance that a beam of light, moving in a straight line, travels in one year. [3] The unit most commonly used in professional astronomy is the parsec (symbol: pc, about 3.26 light-years) which derives from astrometry; it is the distance at which one astronomical unit subtends an angle of one second of arc.[2]. Galaxies themselves span from a few thousand to a few hundred thousand light-years in diameter, and are separated from neighbouring galaxies and galaxy clusters by millions of light-years. In our galaxy of hundreds of billions of stars, this pushes the number of planets potentially into the trillions.
