How are ratios used in astronomy? - Answers

The parsec is a unit of distance equivalent to about 3.26 light years or 31 trillion kilometres. It is used to measure the distances to stars, with kilo and mega parsecs being used for objects further away. A parsec is based on the tangent ratio. The angle in question is that subtended at the distant object by the lines joining it to the earth and the sun, and the opposite side is the earth-sun distance - 1 astronomical unit (AU). The result is the distance of the object from the sun.
