Which planetary body orbits the Earth?
The Moon is the planetary body that orbits the Earth.
What is one planetary body?
Mars is a planetary body.
What is the weight of the body at the center of the earth?
In theory, at the center of the Earth you would have no weight.
What term is applied to any star that is the center of a planetary system?
A sun is a star that is the center of a planetary system.
What is the force of gravitation between the earth and a body at the centre of earth?
The gravitational force between the earth and a body at the center of the earth would be 0 Newtons or 0 lbf. F=G (m1*m2)/r^2 r = zero if the center of the body is at the center of the earth
What is the invisible force of nature that pulls matter towards the center of major planetary bodies such as earth?
Gravity is the invisible force of nature that pulls matter towards the center of major planetary bodies such as Earth. This force is responsible for keeping planets in orbit around the sun and for holding our feet firmly on the ground.
What is the significance of the mass center of Earth in relation to gravitational forces and planetary motion?
The mass center of Earth is important in gravitational forces and planetary motion because it is the point around which all objects are attracted due to gravity. This affects the way planets move in their orbits around the Sun and how objects fall towards the Earth. Understanding the mass center helps scientists predict and explain the behavior of celestial bodies in space.
What was the difference between the geocentric theory and the helicentric theory?
Geocentrism places Earth at the center of the planetary system. Heliocentrism, correctly, places the sun at the center, hence: the Solar System.
What is weight of the body at the center of the earth?
Zero
What is the baddest thing that could happen to earth?
The earth could be devestated by an extinction level event. I.e. planetary imact with a comet or large space body.
What is the main different between the geocentric and heliocentric models of planetary motion?
in a heliocentric system earth and the other planets revolving planet's a geocentric system ,earth is at the center of the revolving planets
Why is earth a planetary body?
Earth is considered a planetary body because it is a large, celestial object that orbits the Sun, is spherical in shape due to its own gravity, and has cleared its orbit of other debris. It exhibits characteristics typical of planets, such as a solid surface, an atmosphere, and geological activity. Additionally, Earth supports life, making it unique among known planetary bodies. These features are consistent with the definitions used by astronomers to categorize planets within our solar system.
