Why are astronomical units used?
Elena Antonovaastronomers use the unit astronomical unit (A>U>)to measure distances between planets and between Sun and planets and other bodies in solar system.
The average distance between the sun and Earth is 149597870 kilometers, which is a convenient unit of measurement in the solar system.
