What are other lunar physical properties, including its orbit and rotation?
The orbit of the Moon is circular, and it spins around the Earth in the same manner as the planets spin around the Sun, i. e. in the counter-clockwise direction. The Moon revolves around the Earth at roughly 2,300 miles, or 3,700 kilometres, per hour. Also, as any other big space object, the Moon rotates on its axis. The full circle of its rotation completes about once every 27.32 days – in other words, one lunar day lasts almost one earthy month! The distance from the Earth to the Moon is measured at about 384,400 km and the Moon is also slowly receding from the Earth (an annual rate of the receding is about 3.74 cm.). – Is there any atmosphere on the surface of the Moon? The Moon does have some atmosphere, although it is definitely not suitable for human lungs. To be exact, the lunar atmosphere has a mass of 10,000 kg, which is about 14 times less than that of the Earth. The lunar “air” is composed mostly of hydrogen and helium, which come from the Solar Wind, with an addition of neo
