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. Meer weergeven 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 Meer weergeven 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, and he used a 160-millimetre (6.2 in) heliometre designed by Joseph von Fraunhofer. … Meer weergeven 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 … Meer weergeven 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) and the speed of light (299792458 m/s). Both of these values are … Meer weergeven Distances expressed in light-years include those between stars in the same general area, such as those belonging to the same spiral arm Meer weergeven The way to calculate the light-year distance: where: Meer weergeven • 1 petametre (examples of distances on the order of one light-year) • Distance measures (cosmology) Meer weergeven Web1.4K views, 92 likes, 20 loves, 20 comments, 4 shares, Facebook Watch Videos from Kristin And Jamil: CRAZY Storytime While Eating our FAVORITE Chinese...
