A light-year, alternatively spelled light year (ly), is a unit of length used to express astronomical distances and is equal to exactly 9,460,730,472,580.8 km (Scientific notation: 9.4607304725808 × 10 12 km), which is approximately 5.88 trillion mi.
9 lip 2024 · For most space objects, we use light-years to describe their distance. A light-year is the distance light travels in one Earth year. One light-year is about 6 trillion miles (9 trillion km). That is a 6 with 12 zeros behind it!
7 lip 2024 · A light year is a unit of measurement used in astronomy to describe the distance that light travels in one year. Since light travels at a speed of approximately 186,282 miles per second (299,792,458 meters per second), a light year is a significant distance — about 5.88 trillion miles (9.46 trillion km) .

A light year is the distance that light travels in one year. The year used by the International Astronomical Union is 365.25 days. A light year is defined as exactly 9,460,730,472,580.8 kilometers.
8 lip 2024 · One light year is approximately 9.46 trillion kilometers, so we can use this conversion factor to convert between the two units. For example, if we want to know how many kilometers are in 2 light years, we would multiply 2 by 9.46 trillion kilometers to get 18.92 trillion kilometers.
1000 Light years = 3.1038479019029×1019 Feet. 1000000 Light years = 3.1038479019029×1022 Feet. Light years to Feet. Convert between the units (ly → ft) or see the conversion table.
