WebJan 14, 2024 · In one Earth year of 364.25 days (8,766 hours), light travels a distance of 5,878,625,370,000 miles (9.5 trillion km). This distance is referred to as one light year. The most distant space probe, Voyager 1, was about 18 light-hours (130 au,19.4 billion km, 12.1 billion mi) away from the Earth as of October 2014. It will take about 17 500 years to reach one light-year at its current speed of about 17 km/s ( 38 000 mph , 61 200 km/h) relative to the Sun. 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 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. … 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 … 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) and the speed of light (299792458 m/s). Both of these values are included in 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: where: See more • 1 petametre (examples of distances on the order of one light-year) • Distance measures (cosmology) See more
