Why are large astronomical bodies round?
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.
Why does the gravitational force between the Earth and moon predominate over electrical forces?
Between the Earth and the Moon, for example, there is no net electrical force. So the weaker gravitational force, which is only attracts, remains as the predominant force between these bodies.
What kind of force is exerted on heavenly bodies?
gravitational force is exerted on heavenly bodies
What is the second largest source of gravity?
On Earth the largest source of gravitational force that we feel is the Earth.The second largest source of gravitational force that we feel is the Sun.The third largest source is the Moon....and the fourth is anyone we stand really close to.
What is syzygy?
Syzygy is a term used in astronomy to describe the alignment of three celestial bodies, typically the Sun, Earth, and Moon. It can also refer to the alignment of planets in the solar system. Syzygy can impact tidal forces and gravitational interactions between these bodies.
what astronomical bodies would most likely be the largest?

What does the magnitude of the gravitational force between two bodies depend on?
The magnitude of the gravitational force between two bodies depends on the mass of the bodies and the distance between them. The larger the mass of the bodies, the greater the gravitational force, and the closer the bodies are, the stronger the gravitational force.

Do 2 co-orbiting bodies have equal speed?
Only if they have equal masses (in the case of gravitational orbits), or equal electric charges (in the case of electrostatic orbits).
Is there UP in space?
No; the directions up and down are defined by the gravitational attraction of nearby bodies only.No; the directions up and down are defined by the gravitational attraction of nearby bodies only.No; the directions up and down are defined by the gravitational attraction of nearby bodies only.No; the directions up and down are defined by the gravitational attraction of nearby bodies only.
What does the moon And the Stars have in common?
They are astronomical bodies.
What holds bodies in their positions in the solar system?
A combination of the bodies' inertia, and the Sun's gravitational attraction.
Why does the gravitational force between the Earth and moon predominate over electrical forces?
Between the Earth and the Moon, for example, there is no net electrical force. So the weaker gravitational force, which is only attracts, remains as the predominant force between these 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.
Are gravitational forces always present in interactions between celestial bodies?
Yes, gravitational forces are always present in interactions between celestial bodies.
What blocks out the visibility of stars?
Cosmic dust and other astronomical bodies.
What kind of force is exerted on heavenly bodies?
gravitational force is exerted on heavenly bodies
