Facts About The Moon: The Earth’s Only Satellite

The Moon in our sky at night is one and the only natural satellite of planet earth. The moon is one quarter in diameter compared with earth and that makes it the largest natural satellite relative to the size of its planet in the entire Solar system. So, here in this post, I have discussed some interesting facts about the Moon.


Distance And Terrain


It is the fifth-largest natural satellite. The moon is at a distance of about 384,000 from the earth. The gravitational influence of the moon is responsible for the sea tides. A moon is a planetary-mass object. It has rocky terrain and craters on its surface.


Some Facts About The Moon


One of the facts about the Moon is it does not have any atmosphere, magnetic field, or hydrosphere. Moon has only 1/6 of earth’s gravity. Among all the natural satellites in the Solar system, Jupiter’s moon Io has the most density and surface gravity.


The moon completes one orbit around the sun every 27.3 days. With respect to Earth, the moon is tidally locked which means one complete rotation of the Moon on its axis is equal to its synodic period.


From Earth we can only see “the near side” of the moon and because the moon is tidally locked to earth so we can only see only 59% of the total surface of the moon.


The Earth’s Moon is the only natural satellite in the Solar System with an atmosphere. Over 95% of the Moon’s mass is in its interior. The moon’s inner structure includes crust, mantle, and core. Moon has a 240 kilometers solid-long inner core rich in iron.  


It is believed that many comets and asteroids had collided with the Moon in the past. Estimates say that the “near side” of the Moon has about 300,000 craters wider than 1 kilometer in length.


So other facts about the Moon include, it is a big natural satellite compared to its planet. It has a mass of 1/81 of the total Earth’s mass. The moon is also the largest natural satellite for any planet. Charon Pluto’s moon is about 1/9 of total Pluto’s mass but Pluto is a dwarf planet in the Kuiper belt.


 Which planet does the moon belong to?


The Moon belongs to Earth. In terms of distance, the Earth is the third planet from the sun. The moon is the Earth’s only natural satellite.


Is the moon a planet or a star?


The moon revolves around the Earth. It is neither a planet nor a star but a natural satellite to Earth.


How many moons does the earth have in 2020?


The earth has one and only natural satellite known as “The Moon”.


Can we survive without the moon?


The moon has lots of influences on earth. It influences weather, tides of the ocean, hours of a day, etc. Without the moon, our nights would become darker and our seasons would be permanently changed. The length of hours and days would increase too.


Is the moon a dwarf planet?


Moon is not a dwarf planet. According to the definition of the International Astronomical Union (IAU) a dwarf planet is an astronomical body that revolves around the Sun. Since the Moon revolves around planet Earth not the sun it is a natural satellite of Earth.


Is it true that the moon is the brightest object in the sky?


Our Moon is the brightest object after the Sun. Also, brighter than all other planets and their moons.


What qualifies as a moon?


A moon is a natural body that orbits a planet, minor planet, or dwarf planet. Six planets in our solar system have their natural moons including Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. The dwarf planet Pluto has five moons and Charon is its largest moon. The largest moon of Jupiter is Ganymede which is also the largest moon of the Solar system and the ninth-largest body.
