How well do you know Earth's Moon? How did it form, rotation, its orbit? Get up close and familiar- 5 points
Moon
1/5 How did the Moon form? According to the information provided by NASA, the leading theory behind the formation of the Moon is that a Mars-sized object collided with Earth billions of years ago, and debris from this collision eventually formed the Moon. (NASA)

2/5 Moon's rotation: The time it takes for the Moon to rotate once on its axis is equal to the time it takes for the Moon to orbit once around Earth. This keeps the same side of the Moon facing towards Earth throughout the month. (NASA)

3/5 Moon orbit Earth: According to NASA, the Moon takes about one month to orbit Earth (27.3 days to complete a revolution, but 29.5 days to change from New Moon to New Moon). As the Moon completes each 27.3-day orbit around Earth, both Earth and the Moon are moving around the Sun. Because of this change in position, sunlight appears to hit the Moon at a slightly different angle on day 27 than it does on day zero ― even though the Moon itself has already traveled all the way around Earth. It takes a little more than two additional days for sunlight to hit the Moon in the same way it did on day zero. This is why it takes 29.5 days to get from new moon to new moon, even though it doesn’t take quite that long for the Moon itself to travel once around Earth. (NASA)

4/5 Does the Moon have gravity? What would happen if there was no Moon? The Moon does have gravity. Because the Moon has less mass than Earth, its gravitational pull is weaker (about one-sixth of Earth’s). On the Moon, you will be able to jump about six times as high as you can on Earth ― but you would still come back down, informs NASA. Also, If there would be no Moon, Earth would be a very different world. The Moon’s gravity keeps our planet from wobbling on its axis too much, which helps to stabilize our climate. The Moon also plays an important role in creating tides in Earth’s oceans. (NASA)

5/5 Who Has Walked on the Moon? Neil Armstrong and Edwin "Buzz" Aldrin were the first of 12 human beings to walk on the Moon. Four of America's moonwalkers are still alive: Aldrin (Apollo 11), David Scott (Apollo 15), Charles Duke (Apollo 16), and Harrison Schmitt (Apollo 17). In all, 24 American astronauts made the trip from Earth to the Moon between 1968 and 1972. Three astronauts made the journey from Earth to the Moon twice: James Lovell (Apollo 8 and Apollo 13), John Young (Apollo 10 and Apollo 16), and Gene Cernan (Apollo 10 and Apollo 17). (NASA)

Noble gases available in the Earth’s Mantle are linked with the origin of the Moon. Here’s how. (NASA)

How was the Moon formed? This question has always kept scientists hooked and numerous heavily debated theories about how the moon was formed have been rolled out over the decades. In the latest efforts, a team of geochemists, cosmochemists, and petrologists has found an undiscovered link between Earth and the origin of Moon. The discovery works as an essential piece of the puzzle in understanding how not just the Moon but other celestial bodies such as Earth have formed. It adds to the previously found strong theory named "Giant Impact" theory, which marvellously argues that the Moon was formed by a massive collision between Earth and another celestial body.

In a study published in the journal, Science Advances, conducted by researchers from Eidgenossische Technische Hochschule (ETH), Swiss Federal Institute of Technology Zurich, has discovered an interesting angle in the origin of the Moon which is said to be inherited from the noble gases from the Earth's mantle. Cosmochemist Patrizia Will, the lead researcher at Washington University said in a statement, "Finding solar gases, for the first time, in basaltic materials from the Moon that are unrelated to any exposure on the lunar surface was such an exciting result.”

How scientists discovered the link between Earth's Mantle and Moon's origin

The researchers examined six samples of Moon's meteorites from an Antarctic collection obtained from NASA. According to the study, meteorites were composed of basalt rock that formed when magma rises from the Moon's interior and cools down quickly. "They remained covered by additional basalt layers after their formation, which protected the rock from cosmic rays and, particularly, the solar wind. The cooling process resulted in the formation of lunar glass particles amongst the other minerals found in magma," the research paper mentioned.

The team discovered that the glass particles retain the chemical fingerprints of the solar gases such as helium and neon from the Moon's interior. The findings of the research strongly support that the origin of the Moon was inherited from the noble gases indigenous to the Earth. You can read more details here.
