What is distance of 1 AU expressed in parsec?

Distances expressed in fractions of a parsec usually involve objects within a single star system. So, for example: One astronomical unit (au), the distance from the Sun to the Earth, is just under 5×10−6 pc. The most distant space probe, Voyager 1, was 0.000703 pc from Earth as of January 2019.

Why is Earth 1 AU from the Sun?

From an average distance of 93 million miles (150 million kilometers), Earth is exactly one astronomical unit away from the Sun because one astronomical unit (abbreviated as AU), is the distance from the Sun to Earth. This unit provides an easy way to quickly compare planets’ distances from the Sun.

What is AU vs light-year?

The Light Year is about 64,500 times larger than the Astronomical Unit, too large to be appropriate for an object the size of our solar system. The Light Year is fine for measuring distances to stars or other galaxies but not for measuring distances within our own solar system.

Why is AU and light-year?

A light year is the distance light travels in a year. Light moves super-fast, so that’s a really big distance. One light year is almost six trillion miles. And an astronomical unit is the average distance between the earth and the sun.
