Was The Moon Once Part of The Earth?- By 3Jackass

Origin of the Moon refers to any of the various explanations for the formation of the Moon, Earth's natural satellite. The leading theory has been the giant-impact hypothesis. The study pushes back the clock on the origin of Earth's water by hundreds of millions of years, to around 4.6 billion years ago, when all the worlds of the inner solar system were still forming. Scientists had suspected that our planet formed dry, with high-energy impacts creating a molten surface on the infant Earth.

At this time, an object about the size of Mars struck the Earth. This early planet, which has been named Theia, was partially absorbed into the Earth, but a large amount of debris was also sprayed out into space. Gravity pulled the debris into orbit around our planet and, as the numerous fragments collided, they began to clump together. The Moon was formed as these clumps grew larger and larger. This is because the Moon rotates around on its own axis in exactly the same time it takes to orbit the Earth, meaning the same side is always facing the Earth. The side facing away from Earth has only been seen by the human eye from spacecraft. The rise and fall of the tides on Earth is caused by the Moon. Rock samples gathered by the astronauts gave us a better understanding of the Moon and provided evidence used to support the so-called "giant impact hypothesis"

The Moon is unprotected from cosmic rays, meteorites and solar winds, and has huge temperature variations. The lack of atmosphere means no sound can be heard on the Moon, and the sky always appears black. There are two bulges in the Earth due to the gravitational pull that the Moon exerts; one on the side facing the Moon, and the other on the opposite side that faces away from the Moon, The bulges move around the oceans as the Earth rotates, causing high and low tides around the globe. The Moon is moving approximately 3.8 cm away from our planet every year. It is estimated that it will continue to do so for around 50 billion years. By the time that happens, the Moon will be taking around 47 days to orbit the Earth instead of the current 27.3 days.

The first spacecraft to reach the Moon was Luna 1 in 1959. This was a Soviet craft, which was launched from the USSR. It passed within 5995 km of the surface of the Moon before going into orbit around the Sun. The first man to set foot on the Moon in 1969 was Neil Armstrong on the Apollo 11 mission, while the last man to walk on the Moon in 1972 was Gene Cernan on the Apollo 17 mission. Since then the Moon has only be visited by unmanned vehicles.

During the 1950’s the USA considered detonating a nuclear bomb on the Moon. The secret project was during the height cold war was known as “A Study of Lunar Research Flights” or “Project A119” and meant as a show of strength at a time they were lagging behind in the space race.
Your weight on the Moon is 16.5% what you would experience on Earth. In other words, if you weighed 100 kg on Earth, you would weigh a mere 16.5 kg on the Moon. Reason behind the differences in weight between the various planets is the gravitational force which a planet is subject to.

 

Earth has much more mass than the moon. Therefore, the sun pulls on it with greater force, because of the greater mass. You probably are familiar that gravity is a downward force. It pushes you back to the Earth's surface. This is why when you jump, you come back down. Being that the earth has greater gravitational force, it pulls object downward with greater force. This translates into greater weight. Because your weight on the Moon is about 1/6th your weight on Earth, but your muscles are still as strong, you could do some amazing things. You would be able to jump 6 times higher, or jump off the roof of a house and be unharmed. And here’s the coolest thing. Strap on a pair of wings inside an air-filled dome on the Moon, and you would be able to fly around with just your own muscle power.
