How big is the Moon compared to the Sun and Earth?

by Wayne Boyd

This is an interesting question. I’m going to answer it with illustrations.

In answer to “How big is the Moon compared to the Sun and Earth?” I’m going to give you some illustrations that will put all of this into perspective. First, let’s look at a comparison of our Moon with Pluto and other dwarf planets in our solar system. Here’s a picture to illustrate.

So here you can see our Moon is quite large! In fact, it’s so large, it’s bigger than all of the known dwarf planets in our solar system, including Pluto!

Even though the Moon is bigger than Pluto, it’s not big compared to Earth. Here’s the comparison of that.

So the moon is relatively small compared to our big Earth. But when you bring the Sun into the mix, then you have to understand that Earth itself is not very big. In fact, the Sun is so big it dwarfs even Jupiter. Here’s the image of that comparison:

So to sum up, our Moon is big compared to Pluto and other dwarf planets in our solar system, but small compared to Earth. Earth itself is like a pebble of sand compared to the size of our Sun. Fortunately for us, the sun is also a long way away, and therefore looms the same relative size as the Moon in our sky.

I hope that sheds some light on the subject! Thanks for asking a cool question.

Venus, Mars and Uranus

If you look outside just after sundown, you will see tonight a very bright star towards the east. That’s not really a star. That’s Venus!
Venus is called our sister planet because it is very near the size of Earth and is on the inside edge of the Goldilocks zone. Scientists believe that if life exists on other planets then those planets must be within a certain Goldilocks zone from their sun.
Just above the bright light of the planet Venus, and a little bit to the left, you will see a very tiny point of light which is slightly orange in color. That’s Mars.
And just above Mars also to the left is Uranus. Of course, you can’t see Uranus with the naked eye. You need a very powerful telescope for that. But it’s there tonight and if you’ve got a telescope like the one below go have a look!
