What Is Bigger, The Earth Or The Moon?

Whenever we see the full moon shining high in the sky, one question often arises in our minds; is the Moon bigger than our planet Earth? When we think about it many more questions rush our mind; what is the actual size of Earth and Moon, how far away the moon is from Earth. Here, we are going to provide you the basic/preliminary knowledge about the Earth and Moon.

What Is Bigger, The Earth Or The Moon

What is Moon?

Moon is, in fact, a Satellite of Earth and revolves around the Earth. Earth is a part of one of the thousands of Galaxies roaming around the Universe. Previously, the Astronomers were of the firm view that our Galaxy consists of 9 planets that orbit around the Sun. But latest one of these, named as Pluto is not considered as Planet anymore. Therefore, as of today, our Galaxy consists of 8 Planets, Earth being one of these.

Each Planet has its Satellites. Most of the Planets have more than one Satellite; Earth has only one, which we know as Moon. However, our initial question is still there, which one is bigger, the Earth or the Moon? Let us try to work out this.

What’s The Earth Size?

Apparently, it seems that Moon is a huge mass which might be larger in size than the Earth. This is not true. In fact, Earth is 36 times larger than the Moon with total surface area 10 times that of the Moon. If the size of Moon is compared with the other Satellites of our Solar System, we come across the fact that it is the largest satellite in terms of relative size of their Planets.


Earth, although a bigger planet than its Satellite, is however not the largest one in our Galaxy. All eight planets of the solar system vary in their respective size and volume. There are thousands of tiny/small planets in our Universe. However, the smallest planet in Solar System is Mercury whereas the largest one is Jupiter, which is 11 times larger than our Planet Earth. Similarly, Earth is 109 times smaller than the Sun.

The actual length of the Earth (the equator) is 40030 kilometers or 24874 miles. Earth’s actual area is considered to be 197 million square miles or approximately 510 million square Km. Also, the Earth is not a perfect sphere, as we normally imagine. It, in fact, resembles the shape of a pear. The upper side of Earth is wider than the lower.

Size Of Moon

As said earlier, Moon is far smaller than the Earth. The diameter of the Moon is 2159 Miles (3476 Kilometers) long. The weight of the Moon is around 80 times less than that of our Planet Earth. As seen from the Earth, it appears that the Sun & Moon is almost of the same size. Fact is that Moon is thousands of times less in size as compared to the Sun.


The question that arose up here is why area of the sun and a moon are relatively same? It is because of their distances from the Earth. Sun is very far away from the Earth as compared to Moon, that is why their size apparently seems to be the same. Moon is 386000 Kilometers away from Earth whereas the Sun is very far away than that.

How The Size Of Moon Changes?

It looks quite strange that the size of Moon is bigger when it first appears in the sky but as it ascends in the sky, its size becomes smaller and smaller. This is, actually, an optical illusion; the size of Moon is a constant thing that does not change at any time.

Then why we see different sizes of Moon? The reason is the path (orbit) of the Moon around the Earth is not a perfect circle in actual. Difference between the nearer and the farther point on this Orbit is around 40000 Kilometers or 25000 Miles. So, when the Moon is the most nearest to earth it looks bigger but when it is on farthest point its size looks small.

How The Moon Is Useful And What Is Its Impact On Earth?

The Moon looks beautiful and has a romantic effect, especially the full moon. But this is not the only impact the Moon has on Earth. Moon is, in fact, a vital element of our ecosystem; it helps in keeping a balance in different ecosystems of the Earth. Through its gravitational pull on the terrestrial sphere Ocean waves, currents and tides are formed.

How The Moon Is Useful And What Is Its Impact On Earth-

If you are living near an Ocean, you can easily observe that during the full moon nights tides are very high as compared to the other nights. It is very important for marine life. It also helps to keep the climate optimal for life on earth.

Without its effect on our climate, the weather would have been much harsher. Without its effect, we may face very violent and high-speed winds. Level of oxygen would increase much and the magnetic field increased almost three times.
