Important facts of Moon
Earth's Moon location in the Solar System:
The Moon is the only natural satellite of the Earth. Moon is the largest natural satellite in the Solar System relative to the size of its planet and only One-Quarter the diameter of the Earth. Moon is fifth largest satellite in the Solar System and overall larger than any dwarf planet.
The average distance of the Moon from the Sun is same as Earth. Since the Moon orbits the Earth and the Earth orbits the Sun, both the Moon and the Earth are the same average distance away from the Sun. The average distance of Earth and Moon from the Sun is about 150 million kilometres (or 93 million miles).
The average distance of the Moon from the Earth is about 240,000 miles (385,000km).
This distance is equivalent to 0.00257 Astronomical Unit.
Light from the Moon takes 1/3 seconds to get from the Moon to Earth.
Occasionally, the name Luna used in scientific writing for Moon and especially in science fiction to distinguish the Earth's moon from others, while in poetry "Luna" has been used to denote personification of Earth's moon. Cynthia is another poetic name. Selene in Greek religion, the personification of the moon as a goddess.
Moon Equatorial Diameter is 3476.2 km.

Ten Important facts of Moon
The average distance of the Moon from the Earth is about 240,000 miles (385,000km).
Moon is fifth largest satellite in the Solar System and overall larger than any dwarf planet.
Moon takes 27.321661 day to complete one rotation.
Moon rotates on its axis at a speed of 4.627 m/s (16657.2 Km/h)
Moon takes 224.701 Earth day (0.615198 Earth Year) days to complete one revolution of the Sun.
Moon orbits around the Earth at a speed of 1.022 km/s or 3679.2 km/hour

The Earth and Moon are tidally-locked. Their rotations are so in sync we only see one side of the Moon all the time. Human's didn't see the lunar far side until a Soviet spaecraft flew past in 1959.
Earth's Moon is the only place beyond Earth where humans have set foot.
The Moon is a rocky, solid-surface body with much of its surface cratered and pitted from impacts.
Physical characteristics Moon
The Moon is a rocky, solid-surface body with much of its surface cratered and pitted from impacts.
The Moon is a very slightly scalene ellipsoid due to tidal stretching, with its long axis displaced 30° from facing the Earth (due to gravitational anomalies from impact basins). Its shape is more elongated than current tidal forces can account for.
Atmosphere of Moon
Lunar Eclipse | What is Lunar Eclipse?
A total lunar eclipse occurs when the Moon and Sun are on opposite sides of Earth.
A partial lunar eclipse happens when only part of Earth's shadow covers the Moon.
During some stages of a lunar eclipse, the Moon can appear reddish because the only remaining sunlight reaching the Moon at that point is from around the edges of the Earth, as seen from the Moon's surface.
Life
No evidence of life has been found on Moon
