A light year is the distance light travels in one year. Light travels at 299792.458 km/s.
The moon is about 1.278 light-seconds from Earth.Converting that figure to the equivalent fraction of a year, I get0.000 000 040 486 light-year (rounded)
Good rounding! The exact number of miles of a light-year is 5,865,696,000,000 miles. The farthest scientists have ever seen is about 13.5 trillion light-years. To figure out how many miles that is you would multiply the 2 numbers together. Cool huh?
The figure isn't unanimously agreed. In a quick web search, we found estimates ranging between 315 and 525 light years.
None. "Year" is a period of time, but "light year" is a distance ... the distance light travels in a year. If a distance could be converted to a time, then you'd be able to figure out how many minutes wide your bedroom is.
The thickness of the Milky Way is still a matter of debate amongst scientists, and even in part still open to definition; the figure of 1,000 light years is often quoted; but recent studies tend to indicate a higher figure. One particularly extensive study aimed at finding the answer to this question led by Bryan Gaensler in 2008 puts the figure at between 6,000 and 12,000 light years, if you include stars and gas.

An astronomical archminute consists of 2000 light years. One can define the size of a galaxy by light years or archminutes. the closest spiral galaxy to our own is known as the M31 galaxy in the constillation Andromeda (all facts can be backed up, just search M31 and Andromeda on simple google search to confirm).The M31 galaxy is 200,000 light years wide and 100,000 light years high. also known as 100 archminutes by 50 archminutes. of coarse all of these measurements go back to the simple base figure of the speed of light.1 light year = distance light travels in a year1 archminute = distance light travels in 2000 years
Light years is a measure for distance, the distance light travels in one year. For the light to travel 587 light years, it takes 587 years.
In 4.34 light years, there are...[da-dah]...4.34 light years. If you mean how far is 4.34 light years, then: 1 light year is the distance light travels in 1 year which is about 9.46x1012km, so in 4.34 light years, it travels about 41.06x1012km ~= 25.66x1012miles.
It takes light 40 years to travel a distance of 40 light years.
