The moon is about 1.278 light-seconds from Earth.
Converting that figure to the equivalent fraction of a year, I get
0.000 000 040 486 light-year (rounded)
The moon is about 0.0000000406 light years away from earth. Clearly, the moon is MUCH too close (238,000 or 239,000 miles or so) for the distance to be rendered meaningfully in light years.
The distance to the moon is about 1.3 light seconds or about 0.000000032 light years.
Much less than a light-year. A light-year is the distance light travels in a year; from the Moon, the light takes only a bit more than a second. The Moon is at an average distance of about 380,000 km. A light-year is about 9,500,000,000,000 km. If you divide the first number by the second, you'll get the number of light-years as a decimal.
As the moon gets further and further away, the gravitational force between the Earth and the Moon decreases. Because the Moon is not being attracted but being pushed away from the Earth. If the gravitational force would have increased, the moon would come closer and closer to the Earth.
About 1 second away every 50,000 years

Anything can be measured in light time. The moon is about 1.3 light seconds (0.0000000412 light years) from the earth. The closest star system, which includes Alpha Centauri, is 4.3 light years away.

The sun sets a glare on only one part of the moon each day. During a full moon the moon reflects light towards the Earth. During a new moon the moon reflects light away from the Earth.

At its average distance from the earth, the moon is 1.28 light seconds away.
That's the moon.
The average distance to the Moon is 384,399 kilometres = 4.06318742 × 10-8 light years (Note the minus) The moon is only a tiny fraction of one light year from earth. It takes light from the sun eight minutes to reach earth, and the moon is much closer to earth than the sun. Measuring such a small distance in light years is possible but impractical. ======================================= The moon is roughly 1.27 light seconds from the earth. (rounded) 1.27 light seconds is the same as 0.0000000406 light year. (rounded)
Ananke is a moon of Jupiter, and like the Earth, all orbit the Sun, and so the distance varies.
The moon is drifting away from earth at a rate of about 38 millimeters per year. So in 1 million years, the moon will have drifted another 38 kilometers or abour 24 miles further from Earth.
