Answer 2

Why don't planets fly away from stars?

Planets do not fly away from stars because they are held in orbit by the gravitational force between the planet and the star. The gravitational force is the attractive force between two objects with mass. In the case of planets and stars, the star's mass is much larger than the planet's mass, so the star exerts a strong gravitational force on the planet, keeping it in orbit.

Gravity is a fundamental force in the universe that acts over long distances. It is responsible for keeping celestial objects, such as planets, moons, and asteroids, in stable orbits around stars. The gravitational force between a planet and a star depends on the mass of the planet, the mass of the star, and the distance between them.

The force of gravity between the planet and the star pulls the planet towards the star, while the planet's motion in a forward direction creates a centrifugal force that tries to pull the planet away from the star. These two forces balance each other out, resulting in a stable orbit where the planet continuously revolves around the star.

The key factors that prevent planets from flying away from stars are: 1. Gravitational force: The gravitational force between the planet and the star keeps the planet in orbit around the star. 2. Centrifugal force: The planet's motion in a forward direction creates a centrifugal force that counteracts the gravitational force, preventing the planet from falling into the star.

It's important to note that the stability of a planet's orbit depends on various factors, including the mass of the planet and the star, as well as the distance between them. If the gravitational force is too weak compared to the centrifugal force, the planet may escape from its orbit and move away from the star. Conversely, if the gravitational force is too strong, the planet may spiral into the star.

In summary, planets do not fly away from stars because they are held in orbit by the gravitational force between the planet and the star. The gravitational force and the centrifugal force work together to maintain a stable orbit for the planet around the star.
