Lightyears A light-year is a unit of length used in astronomy to measure vast distances. One light-year is equivalent to approximately 9.461 trillion kilometers or about 5.879 trillion miles.
A light-year is defined by the distance that light travels in a vacuum in one year, which is about 9.461 × 10^12 kilometers.
Light-years are used to measure distances between stars, galaxies, and other celestial objects. They provide a convenient way to express astronomical distances, making it easier to understand the scale of the universe.
Astronomical Units An astronomical unit (AU) is a unit of length used in astronomy to measure distances within our solar system. One astronomical unit is equivalent to approximately 149,597,870.7 kilometers or about 92,955,807.3 miles.
The astronomical unit is defined as the mean distance between the Earth and the Sun.
Astronomical units are used to express distances between celestial bodies within the solar system, such as the distances between planets and their orbits. They provide a convenient scale for describing and comparing distances in a way that is more manageable than using kilometers or miles.
