A lunar distance ( LD ) is a measurement of the distance from the Earth to the Moon. The average distance from Earth to the Moon is 384,403 kilometers (238,857 miles).
High-precision measurements of the lunar distance are made by measuring the time taken for light to travel between LIDAR stations on Earth and retroreflectors placed on the Moon.
The moon is spiraling away from Earth at an average rate of 3.8 cm per year, as detected by the Lunar Laser Ranging Experiment.
The first person to measure the distance to the moon was Hipparchus, who used simple trigonometry. He was approximately 26,000 km off the actual distance-an error of about 6.8%. Hipparchus was alive during 2nd Century BC.

238857.81 miles from the Earth to the moon and is moving away from the Earth each month per 1 to 1.1242 inch away.
The Earth's distance from the sun is a variation of 14m km to 15m km or 92m m to 93.13m m or 1AU.

Remember if the moon is overhead it is 4000 miles closer than when it is on the horizon. It is an optical illusion that it looks bigger when it is low down. It is in fact smaller

The average distance is about 385,000 km, or about 238,000 miles. It varies depending on what point of the moon's orbit it's at (the orbit is elliptical, not circular).

Yeah, when`re you free? always wanted to go for a Discovery/National Geographic type of journey.
I`ll get the calculator, you get the measure tape.
