Which unit do astronomers use to measure distances within the solar system?

The unit used to measure distances within the Solar System is known as the Astronomical Unit. It is predominantly used as the most suitable yardstick to determine or calculate the distances within the system or throughout the stars within the solar system.

Explanation:

In uranology, the foremost ordinarily used measures of distance are the light year, parsec and Astronomical Unit.

Astronomical Unit (A. U.)

An Astronomical Unit (A. U.) is that the average distance between the world and also the Sun, that is concerning ninety-three million miles or a hundred and fifty million kilometers. Astronomical units live } sometimes accustomed measure distances at intervals our scheme.

Light-Year (ly)

Most objects in-house area unit thus far away, that employing a comparatively little unit of distance, like associate degreeAstronomical Unit, isn't sensible. Instead, astronomers live distances to things that area unit outside our scheme in light-years. A light-weight - year (ly) is that the distance that light will travel in one year in an exceeding vacuum (empty space). Parsec (pc)

Astronomers use another unit of distance known as a secpar (pc), that is capable three. 26 light-years. The definition of the secpar relies on a triangle.
