Moon formation!! Interesting‌‌Facts.. How did the moon form? According to the "giant impact" theory, the young Earth had no moon. At some point in Earth's early history, a rogue planet, larger than Mars, struck the Earth in a great, glancing blow. Instantly, most of the rogue body and a sizable chunk of Earth were vaporized. The cloud rose to above 13,700 miles (22,000 kilometers) altitude, where it condensed into innumerable solid particles that orbited the Earth as they aggregated into ever larger moonlets, which eventually combined to form the moon.
Composition of the moon…. The composition of the moon is roughly 43 percent oxygen, 20 percent silicon, 19 percent magnesium, 10 percent iron, 3 percent calcium, 3 percent aluminum, 0.42 percent chromium, 0.18 percent titanium and 0.12 percent manganese.
Distance between the moon and Earth………… The distance between the Earth and its moon averages about 238,900 miles (384,000 kilometers). The diameter of the moon is 2,160 miles (3,476 kilometers).
Moon affects the Earth? The moon affects the earth in two ways. Its position around the earth allows it to reflect the sun's light into our night. The moon's orbit around the earth lasts about a month giving us different levels of this light.
Moon’s Orbit The Moon appears to move completely around the celestial sphere once in about 27.3 days as observed from the Earth. This is called a sidereal month, and reflects the corresponding orbital period of 27.3 days The moon takes 29.5 days to return to the same point on the celestial sphere as referenced to the Sun because of the motion of the Earth around the Sun; this is called a syndic month (Lunar phases as observed from the Earth are correlated with the syndic month). There are effects that cause small fluctuations around this value that we will not discuss. Since the Moon must move Eastward among the constellations enough to go completely around the sky (360 degrees) in 27.3 days, it must move Eastward by 13.2 degrees each day (in contrast, remember that the Sun only appears to move Eastward by about 1 degree per day). Thus, with respect to the background constellations the Moon will be about 13.2 degrees further east each day. Since the celestial sphere appears to turn 1 degree about every 4 minutes, the Moon crosses our celestial meridian about 13.2 x 4 = 52.8 minutes later each day.

Unmanned and Manned Unmanned: Only eighteen spacecraft have used braking rockets to survive their moon landings and perform scientific operations on the lunar surface – six manned, a dozen unmanned, all launched by either the Soviets or the Americans between 1966 and 1976. The USSR accomplished the first soft landings and took the first pictures from the lunar surface with ruggedized camera packages on their Luna 9 and Luna 13 missions. The Americans followed with five unmanned Surveyor soft landings and six manned Apollo missions. After the American manned Apollo landings, the Soviet Union later achieved sample returns of lunar soil via the unmanned; Luna 16, Luna 20 and Luna 24 Moon landings; their Luna 17 and Luna 21 were successful unmanned rover missions. Not included in this accounting is the Soviet Luna 23 mission, which successfully landed but whose scientific equipment then failed, or the American Surveyor 4, with whom all radio contact was lost only moments before a possible perfect automated soft landing.
Manned: A total of twelve men have landed on the Moon. This was accomplished with two US pilot-astronauts flying a Lunar Model on each of six NASA missions across a 41-month time span starting on 21 July 1969 UTC, with Neil Armstrong and Buzz Aldrin on Apollo 11(with Armstrong being first to set foot on the surface), and ending on 14 December 1972 UTC with Gene Ceman and Jack Schmitt on Apollo 17 (with Cernan being the last to step off the lunar surface). All Apollo lunar missions had a third crew member who remained onboard the Command Module. The last three missions had a rover for increased mobility.
Post Cards! Neil Armstrong: Greetings from space!!! Wish you were here!! I have found that there is no air in space. Always remember to wear your spacesuit!! From where I am standing, the Earth looks so small but from where you are standing, the moon looks really small.
Buzz Aldrin: Hello Earthlings! Don’t worry I do miss Earth but the moon is AMAZING! The moon has no gravity so it’s like a gigantic bouncy house! It’s easy to move around because all you have to do is bounce around.
