The Moon is Earth’s only natural satellite and is the fifth largest natural satellite in the Solar System. The diameter of the Moon is 3,474 km, equal to 27% of the diameter of the Earth. The mass of the Moon is about 2% of the Earth’s mass and the gravitational force at the Moon’s surface is 17% of that on the Earth’s surface.
Despite being the closest neighbor to Earth, as of now we still cannot understand everything around the Moon. Specifically, the question of where the Moon comes from has been a headache for astronomers for centuries. According to the hypothesis agreed by many scientists, the Moon was formed from a collision between Earth and a Mars-sized protoplanet 4.6 billion years ago. Due to this collision, the Earth’s outermost layer was blown outward, forming a molten sphere, which then cooled down and moved away, forming the Moon.
Besides, it is still unclear what is hidden deep inside the central part of the Moon. To uncover the secret, we can drill deep into the core of the Moon, from one side to the other side of this celestial body to reveal unexplored secrets.
