Astronomical units are used to measure distances between celestial bodies. One astronomical unit (au) is equal to the average distance between the Earth and the Sun, which is approximately 149.6 million kilometers.
It is often used as a measure of distance when dealing with planets, stars, and other celestial bodies in the solar system. In addition, it is useful for measuring distances in other parts of the universe, such as the Milky Way and other galaxies.
Astronomical units are also used to measure the size of celestial objects such as planets and stars, as these objects often have sizes that vary by au.
In addition to the astronomical unit (ua), there are also other derived units that are often used in astronomy, including:
It is the distance that light travels in one year (approximately 9.46 trillion kilometers). It is used to measure distances between stars and galaxies.
It is the distance that light travels in one kilometer (approximately 3.3 microseconds). It is used to measure very large distances, such as between galaxies.
It is the distance of a celestial body that has a parallax of one arcsecond when observed from two distinct points that are one light-year apart. It is used to measure very large distances, such as between galaxies.
