1. The Moon is Earth’s only natural satellite and is the fifth largest satellite in the Solar System. The Moon is also the largest natural satellite in the Solar System by the size of the planet it orbits, with a diameter of 27%, a density of 60% and a mass of 1⁄81 (1.23%) that of Earth.

2. Earth has a gravity of 9.8m/s². Meanwhile, the gravity on the Moon is much smaller, at 1.62m/s². The gravity on the Moon is smaller and weaker due to its smaller size compared to the Earth.

3. The Earth has a diameter of about 12,742 km while the Moon has a diameter of about 3,474 km, which is 1/4 of the size of the Earth.

4. According to research, the Moon moves away from Earth about 4 cm every year. If this continues for the next 50 billion years, it will take the Moon about 47 days to orbit the Earth, not 27.3 days like it is now, says the Space Facts page.

5. On the Moon there is no life because the Moon does not have an atmosphere (air) or water, so no living things can live on the moon.

6. Once the Moon rotates it takes 27 days. This is what causes it as if the Moon does not rotate or seems to show the same side to the Earth. The Moon’s rotation will slow down when the Moon is at perigee.

7. The Moon’s rotation is about 27.23 times slower than the rotation of the planet Earth. Earth rotates with a period of 23 hours 56 minutes, the Moon rotates 27.32166 days (27 days 07 hours 43 minutes 12 seconds).

8. The most obvious effect the Moon has on Earth can be seen in the tides. As the Earth rotates each day, the Moon’s gravity pulls the water on the closest side of the Earth toward it, creating a bulge. The sea bulges on the opposite side also due to the centrifugal force caused by the rotation of the Earth.

9. Three effects of the rotation and revolution of the moon that can be seen or felt by us on Earth include the phenomenon of eclipses, the phenomenon of ocean tides and changes in the phases of the Moon.

10. The weight of an object on Earth will be different from its weight on the Moon. An object with a mass of 10 kilograms, will still have a mass of 10 kilograms on Earth and on the Moon, but on Earth, the object will weigh 98 Newtons, while on the Moon, the object will weigh only 16.3 Newtons.

11. The shape of the Moon changes every night because the phases of the Moon depend on the position of the Moon with respect to the Sun. In this phase of the Moon, the Moon, Earth and Sun are aligned with the position of the Moon in the middle

12. In the case of the Moon, the synchronous rotation is due to Earth’s gravity and a phenomenon known as tidal locking or gravitational locking.

13. The difference between star and Moon is that the Moon is a space object, which produces light from reflected sunlight. The stars produce their own light.

14. The temperature during the day on the Moon is reportedly very hot. The difference is too significant because the Moon does not have a thick atmosphere to retain heat. Day temperature on the Moon surface reaches 110 degrees Celsius while at night temperature drops to -173 degrees Celsius.

15. Changes in the shape of the Moon occur based on the position of the Moon in its orbit with respect to the Earth and the position of the Earth in its orbit with respect to the Sun. This position makes the Moon experience 4 main phases, namely the new moon, the first quarter, the full moon and the third quarter.
