Our solar system is one of the most complex yet interesting parts of the universe. Whether adults or children, all are confused about one thing; Why are Earth and other planets round in shape? Do they have a problem with other shapes or what? As funny as this question may sound, it is legitimate, though.

1. Why are Earth and Other Planets Round in Shape?
Our solar system is one of the most complex yet interesting parts of the
universe. Whether adults or children, all are confused about one thing;
Why are Earth and other planets round in shape? Do they have a problem
with other shapes or what? As funny as this question may sound, it is
legitimate, though.
So, are you a student worried about the same innocent question in your
mind? Don’t worry. We are always here to solve all your confusion! In this
post, we will answer the most complex question: Why are all the planets
in our universe round?
But before that, let’s find out if Earth is really round or not? Keep reading!
Is Earth Round?

2. Before diving into the ‘why,’ we first need to figure out if Earth is really
round or not? What? You have not heard about the Earth is flat debate?
We bet you have!
However, no matter how much people say it is flat, one thing is for sure;
Earth is Round. Also, we have known this fact for the past 2000 years or
more. Everything is round and spherical, from the sun to the moon to all
the planets!
But before we explain why they are round, we want to make sure you
know that Earth is round and not flat!
Earth is Round and not Flat? Prove!
Yes, we understand that, like every other thing, you need proof to accept
this point too. Don’t worry; we have the proof for you! The only way to
check if Earth is round and not flat i s to look at it from a distance. And by
distance, we mean a very, very distant perspective!

3. Different astronauts and satellites have helped us to achieve that
perspective. There are countless pictures available that clearly show that
the blue part of the Earth has a curve. However, we have a problem here
too. People who believe that Earth is flat also believe that those pictures
are fake.
However, a 2000-year-old Greek ideology gave us enough proof. A few
Greeks experimented with something with the help of 2 sticks. They fixed
those sticks on the Earth’s surface, with a 500 miles distance in between.
Also, the sticks were in 2 different cities.
The sticks were right under the sunlight, and guess what? The Greeks
noticed that one stick was casting a shadow an d the other one was not. If
the Earth were flat, there would be no shadows. This is only possible
because the Earth had a curve somewhere, right?
Similarly, the Greek Philosopher Aristotle gave us another proof a few
years ago! The Earth always throws a sh adow at the moon every lunar
year. Aristotle focused and observed that the shadow is always in an arc
shape. Now obviously, an arc shadow is only formed when the main object
is round or spherical, right?

4. If Earth is Round, why isn’t this Visible?
I am sure now you wonder if Earth is round, why can’t we see the curve?
Well, because the curve can’t be seen like this. You have to climb 35,000
feet above the sea level to see the curvature finally, that too with the help
of a broad angle view.
You can’t see the curve even if you are flying on an airplane because its
maximum flying capacity is 28,000 above sea level. If you really want to
see the curvature, you will have to cli mb up the space.
Now that we are sure Earth is round let’s explain why it is so!
Why are Earth and all the Planets Round?
Now, here comes the most-asked question, “Why is everything round in
this universe? Why are they not cubes or a triangle?” Well, this is because
of gravity. We all know what gravity is, right? It is a force that pulls on

5. things and objects. From random objects to human beings to trees,
everything in this world and universe contains gravity. Why? Let us
explain.
This is because everything has mass, and where there is mass, there is
gravity. Mass is basically the count of material, and things present inside
something. It can be people, rock, gasses, water, etc.
Issac Newton is the scientist who discovered this concept, and according
to his, one of many rules of gravity, it pulls on everything to the center of
the mass.
When Earth and all the other planets were forming, they wer e made of a
hot liquid. Now, since all the planets and Earth contain mass, the gravity
pulled on from the center when they were formed, squeezed everything
together, and formed a ball shape. When the planets cooled down, they
formed a solid ball shape.

6. That is how we have everything round in this universe!
Final Words
I hope that you found the answer to your question, and that too clearly!
Also, let’s take a minute out to thank God for making all the planets
sphere. Imagine if it were pentagons or hexagons; making the solar
system model would be a dreadful task!
