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, which is approximately 5.88 trillion mi.
NASA/JPL-Caltech. The nearest known exoplanet orbits the star Proxima Centauri, which is four light years away (~24 trillion miles). If a modern-day jet were to fly to this exoplanet it would not arrive for 5 million years. One of the most distant exoplanets is 3,000 light-years (17.6 quadrillion miles) away from us in the Milky Way.
Light-year is the distance light travels in one year. Light zips through interstellar space at 186,000 miles (300,000 kilometers) per second and 5.88 trillion miles (9.46 trillion kilometers) per year. We use light-time to measure the vast distances of space.
13 lis 2009 · A light year is the distance that light travels in a single year. And light travels fast. 1 lightyear is 9,460,730,472,580.8 kilometers. Need some other measurements? A light year...
