Light years are used to measure distances in space.
One light year is how far light travels in a year (it travels at 600,000km per second!).
It is equal to:
One "Astronomical Unit" is (more or less) the average distance between the Sun and Earth.
.73 AU?But the distance from Mercury to the Earth varies greatly as both planets orbit the Sun. At its closest approach, Mercury is about 77 million kilometers (48 million miles) from Earth*. At its farthest, about 222 million kilometers (138 million miles).
1 AU (astronomical unit) is the average distance between Earth and Sun. This is about 150 million kilometers.
The distance between Earth and Mars varies due to their positions in their orbits around the Sun. On average, Mars is about 225 million kilometers away from Earth. However, this distance can change as the two planets move along their respective orbits.
AU is not used to measure the distances on earth, because a astronomical unit is a unit of measurement equal to the distance between Earth and Sun. So that's why you cannot use Au for measure the distances on Earth.

One "Astronomical Unit" is (more or less) the average distance between the Sun and Earth.
It's called 1 Astronomical unit.
It's called 1 Astronomical unit.
Anything about 93 million miles, or close to 150 million km., long.
Equal to what? The Earth ? never.
They have equal distance between them to keep balance.
An AU (Astronomical Unit) is the mean distance between Earth and our Sun . . .149,597,871 kilometers.
An Astronomical Unit is a unit of measurement roughly equal to the average distance between the Earth and the Sun; about 150 Million Kilometres.
