Large astronomical bodies, such as planets and stars, are generally round due to the force of gravity. As these bodies accumulate mass, gravity pulls matter towards the center, creating a shape that minimizes potential energy. This spherical shape allows for uniform distribution of gravitational forces, ensuring stability. Additionally, the fluid nature of materials under high pressure and temperature, particularly in celestial bodies like stars, further promotes a round shape.

What is the definition of the word astronomical?
Astronomical is an adjective that has a couple meanings. The first meaning of astronomical is relating to astronomy, and the second meaning of astronomical is extremely large.
What astronomical fact did Aryabhata demonstrate awareness of?
The earth is round
What does IAU stand for?
IAU stands for the International Astronomical Union, an organization that is responsible for promoting and coordinating the international collaboration in astronomical research. It is also responsible for assigning official names to celestial bodies and features.
Large bodies of rock or gas that revolve around a star are called?
Large bodies of rock or gas that revolve around a star are planets.
Why does gravitational force predominate over electric force for astronomical bodies?
Gravitational force predominates over electric force for astronomical bodies because gravity is a long-range force that acts on all masses, while electric force is a short-range force that is much stronger at small distances but rapidly decreases with distance. In astronomical scales, the masses involved are much larger and the distances much greater, making gravity the dominant force. Additionally, astronomical bodies are typically electrically neutral overall, so electric forces between them are relatively weak compared to gravitational forces.
What makes most celestial large bodies round?
Gravity.
How on earth is the earth round if the earth is round?
It's a slightly flattened (at the poles) spheroid, the last time we checked. When astronomical bodies get large enough, they 'collapse', or shape themselves under the force of their own gravity. Thought experiment: imagine an object made of the same materials as earth and just as large, but it is a rod 100 km in diameter. What do you suppose would happen?
what astronomical bodies would most likely be the largest?

Why are large astronomical bodies such as planet and stars around?
all parts of the planet pulled each other toward the center of the mass by gravity
Why are strong astronomical bodies such as planets and stars round?
A combination of gravity (pulling inward in all directions) and centrifugal force from rotation (pulling outward at the equator) produces a spheroidal shape.
What does the moon And the Stars have in common?
They are astronomical bodies.
What was the astronomical canon about?
The astronomical canon was a compilation of mathematical tables and astronomical data used for making astronomical calculations and observations. It helped astronomers accurately predict the positions of celestial bodies in the sky.

What blocks out the visibility of stars?
Cosmic dust and other astronomical bodies.
Why are large astronomical bodies such and stars round?
Matter of all types have gravity, which causes it to attract to each other. The most efficient way for all this matter to congregate is the sphere. As they consolidate, they form the shape. As they compress, temperatures in the center of the mass start to go up and if it hits the proper point, it can ignite and become a star.
