The universe is vast, dark, and full of wonders. The heavenly bodies that populate the cosmos all have different shapes. Some are spherical, some are elongated, and some even look like a Viking hats! But why do so many celestial objects take on such specific shapes? Let’s explore why all the planets and stars are round in shape.
The universe is filled with stars and planets of all different shapes. From flat arctic circle penguins to cone-shaped turtles to spherical pandas, almost every type of animal we know has either a rectangular or cylindrical body.
While it may not seem like it at first glance, this fact has puzzled scientists for centuries. Why do so many kinds of animals have such unique body types? And why do planets and stars have those same shapes? Let’s explore why the planets and stars are round.
What is a Round Shaped Body?
A round-shaped body has an even width and length. Round bodies tend to be smooth and soft to the touch, which makes them particularly vulnerable to being squished. Being round has its advantages though, as round animals have a wider range of motion, making them more flexible and easier to maneuver.
Round bodies are also advantageous for animals that primarily reside or travel in water because of their size. Smaller bodies typically weigh less and are easier to be carried around by water currents. This is why the most aquatic animals, whether they be fish, crustaceans, or cephalopods, have round bodies.
For these reasons, round-shaped bodies are extremely common among aquatic animals of all shapes and sizes.
Why are Planets Round?
As we explore why the planets are round, let’s start with Earth. As the only planet in our solar system whose shape we can see, it’s a good place to start. Earth is round because of gravity. As gravity pulls objects towards the ground, Earth pulls everything towards its center.
Since the Earth is rotating while this is happening, the force of gravity moves those objects in a circle. Since the ground is curved, everything is pulled towards the center of that curve, making the planet a round shape.
Planets and stars are round because their gravity is strong enough to pull everything toward their center. Planets also require a certain amount of heat to sustain a round shape. If a planet does not have enough heat, it will have a different shape, such as a peanut shape.
Why are Stars Round?
As we explore why stars are round, let’s start with the sun. The sun is a star, so it makes sense that stars are round as well. Stars are round because of gravity and heat. In the same way, the Earth pulls everything towards its center, stars pull everything towards their center.
This is because of the heat inside the stars. Stars are so hot that they create pressure on their surface. This pressure pushes everything toward the center of the star, making it a round shape. Stars are also surrounded by a gas cloud of hydrogen and helium.
This gas cloud also pulls towards the center of a star. When these two forces work together, they make stars a round shape.
What is an Elongated Shaped Body?
An elongated shaped body is one whose width is larger than its length. There are various types of elongated bodies, including a rod, a cylinder, and a cone. Elongated bodies are best suited to performing tasks that require a lot of strength or force.
The best example of an elongated shaped body is a cylindrical shaped body. Cylinders are ideal for storing and transporting large quantities of items because they allow for larger volumes of stuff.
They are also great for performing tasks that require a large amount of force due to their wider surface area. Cylinders are common in machines that require a lot of power and force, like cranes and jackhammers.
Why are Comets Elongated Shaped?
The first question we need to ask is why we think comets are elongated shaped bodies. We know that comets are in our solar system, but they are usually so far away from Earth that we can’t see them. So what makes us think they’re elongated?
It turns out we don’t know the exact shape of a comet. But we can make guesses about what it looks like based on the data we do have. As we explore why comets are round, let’s start with what we know. We know that comets are made of frozen gases and dirt.
We also know that they pass by Earth every once in a while. The reason we think comets are elongated-shaped bodies is that they fly through space at high speeds. Because they are moving so quickly, they pick up speed as they fly through the friction-less void of space.
Comets are frozen gases and dirt, so gravity is pulling them toward Earth. But because they are moving so quickly, they aren’t slowing down. This makes them take the shape of a streamlined object, like an airplane. Since streamlined objects are typically elongated shaped bodies, it makes sense that comets are round.
Why do Constellations Have Unique Shapes?
As we explore why constellations have unique shapes, let’s start with the Big Dipper. The Big Dipper is one of the most recognizable constellations in the world. It has a long history and many cultures have used it for navigation.
The Big Dipper is a group of seven stars that form a large bowl shape. Why do constellations have unique shapes? It is a group of seven stars that form a large bowl shape. The Big Dipper is a group of seven stars that form a large bowl shape.

Can You Tell the Difference Between a Planet and a Star?
The easiest way to tell the difference between a planet and a star is by their size. Planets are smaller than stars and emit much less light. If you were able to get up close to both a planet and a star, you’d notice a few key differences.
Stars are larger than planets, and they emit more light and energy. If you were able to get up close to both a planet and a star, you’d notice a few key differences. Stars are larger than planets, and they emit more light and energy.
