The Moon
Luna is Latin name for the Moon.It may also refer to: Luna (goddess), the ancient Roman divine personification of the Moon.
The Moon is an astronomical body that orbits planet Earth, being Earth's only permanent natural satellite.
Our Moon is only about 1/4 the diameter of the Earth, has less gravity and has craters on its surface that can be seen with the naked eye. The Moon looks bright at night because of sunlight that is reflected off its surface.
Moon Profile
Diameter 3,475 km
Mass 7.35×10^22 kg (0.01 Earths )
Orbits The Earth
Orbit Distance 384,400 km
Orbit period 27.3 days
Surface temperature -233 to 123°C
Origin
The origin of the Moon is usually thought to be that a Mars-sized body struck the Earth, making a debris ring that eventually collected into a single natural satellite, the Moon, but there are a number of variations on this giant-impact hypothesis, as well as alternate explanations, and research into how the Moon came to be continues. Other proposed scenarios include captured body, fission, formed together (condensation theory), planetesimal collisions (formed from asteroid-like bodies), and collision theories.
The standard giant-impact hypothesis suggests the Mars-sized body, called Theia, impacted Earth, creating a large debris ring around Earth, which then accreted to form the Moon. This collision also resulted in the 23.5° tilted axis of the earth, thus causing the seasons.The Moon's oxygen isotopic ratios seem to be essentially identical to Earth's. Oxygen isotopic ratios, which may be measured very precisely, yield a unique and distinct signature for each solar system body. If Theia had been a separate protoplanet, it probably would have had a different oxygen isotopic signature from Earth, as would the ejected mixed material. Also, the Moon's titanium isotope ratio (50Ti/47Ti) appears so close to the Earth's (within 4 ppm) that little if any of the colliding body's mass could likely have been part of the Moon.
There are many theories about origin of the Moon.
MYTHOLOGY
There a lots of myths about moon
1▪The Nazis had a base on the moon.
After World War II, rumors circulated that German astronauts had traveled to the moon and established a top-secret facility there. Some even speculated that Adolf Hitler faked his own death, fled the planet and lived out the rest of his days in an underground lunar hideout. Connections were also drawn between flying saucer sightings—including the famous incident near Roswell, New Mexico, in 1947—with the Nazis’ alleged UFO development program. These theories form the basis of the science fiction novel “Rocket Ship Galileo,” published by Robert A. Heinlein in 1947.
2▪A rabbit dwells on the moon.
Intriguingly, legends from various traditions around the world, including Buddhism and Native American folklore, recount the tale of a rabbit that lives on the moon. This shared myth may reflect common interpretations of markings on the lunar surface—an alternate take on the fabled “man in the moon.” Shortly before Apollo 11 landed on the moon in 1969, mission control in Houston jokingly referred to the Chinese version of the story, telling the spaceship’s crew, “Among the large headlines concerning Apollo this morning, there’s one asking that you watch for a lovely girl with a big rabbit.” Command module pilot Michael Collins replied, “Okay. We’ll keep a close eye out for the bunny girl.”
3▪The moon has a dark side
Despite being the title of Pink Floyd's blockbuster 1973 album, the "dark side of the moon," doesn't actually exist. According to NASA, what we call the "dark side" is actually a "far side." That's because the moon rotates, so there is always 41 percent of the moon's surface that can never be seen from earth. And despite appearances, scientists have figured out that it's not actually dark on the far side. The few dark spots you can see from earth are the result of "volcanic plains." Check out these spooky facts about the moon.
4▪The moon landing didn't really happen
People have vast conspiracy theories covering all the possible reasons why the moon landing in 1969 did not actually happen—and every one of them has been debunked. Conspiracy theorists examined every inch of the footage and asked questions such as, "Why is the flag waving when there isn't a breeze on the moon?" Actually that's "angular momentum"—because the astronauts are twisting the pole and unrolling the fabric. "Why aren't there any stars in the background?" Because the camera technology couldn't capture them. Basically, the moon landing doubters apply earth atmosphere logic to the images. They also don't account for the intricacies of the technology for rockets and cameras.
Landing
Apollo 11 was the spaceflight that landed the first two humans on the Moon. Mission commander Neil Armstrong and pilot Buzz Aldrin, both American, landed the lunar module Eagle on July 20, 1969, at 20:18 UTC.
