As defined by the International Astronomical Union (IAU), a light-year is the distance that light travels in a vacuum in one Julian year (365.25 days). Because it includes the time-measurement word " year ", the term light-year is sometimes misinterpreted as a unit of time . See more A light-year, alternatively spelled light year, is a large unit of length used to express astronomical distances and is equivalent to about 9.46 trillion kilometers (9.46×10 km), or 5.88 trillion miles (5.88×10 mi). As defined by the See more Distances expressed in light-years include those between stars in the same general area, such as those belonging to the same spiral arm See more The way to calculate the light-year distance: $${\displaystyle 299792458\times 60\times 60\times 24\times 365.25}$$ where: • 299 792 458 is the number of meters light travels in one second See more • 1 petametre (examples of distances on the order of one light-year) • Distance measures (cosmology) • Einstein protocol • Hubble length See more As defined by the IAU, the light-year is the product of the Julian year (365.25 days, as opposed to the 365.2425-day Gregorian year or the 365.24219-day Tropical year that both approximate) … See more The light-year unit appeared a few years after the first successful measurement of the distance to a star other than the Sun, by Friedrich Bessel in 1838. The star was 61 Cygni, … See more Distances between objects within a star system tend to be small fractions of a light-year, and are usually expressed in astronomical units. However, smaller units of length can similarly be formed usefully by multiplying units of time by the speed of light. For … See more

WebSo, one solar year is actually 365.25 days long, or 365 days, 5 hours, 48 minutes, and 46 seconds. Leap years happen every four years and add one extra day to the calendar to make up for those extra 5 hours, 48 minutes, and 46 seconds. These hours are rounded up to 6 hours because 6 times 4 is 24.
