Planetary orbits are a balance between gravity, which pulls them toward the Sun, and inertia that keeps them moving forward in the same direction as they are going now. Inertia causes the planets to keep moving just as before, but gravity pulls them toward the Sun. As the planets fall toward the Sun, the inertia (more properly called "momentum") keeps making the planet miss the Sun as it is falling.
What else can I help you with?
Why do the planets all stay orbit around the sun and not drift on in an empty space?
Its because the gravitational field of the sun pulls the planets towards the sun and balances the intertia of the planets which make them want to move in a straight line.
What are the large objects in space that orbit a star such as the sun?
The answer is planets.
What happen to the planet's orbit if there is no sun?
Without the sun's gravity to hold the planets in orbit, they would no longer be bound to their current paths and would drift off into space. The absence of the sun's warmth and light would also have profound effects on the planets' atmospheres and surfaces, potentially leading to freezing temperatures and inhospitable conditions.
What would happpen to a space vehicle in orbit around Earth if it sped up?
If its speed was greater than the pull of gravity - it would simply leave orbit and drift off into space.
Planets without solar systems are called?
Planets not orbiting a star but instead orbiting the galactic center are referred to as rogue planets, or nomadic or interstellar planets.
Why do the planets all stay orbit around the sun and not drift on in an empty space?
Its because the gravitational field of the sun pulls the planets towards the sun and balances the intertia of the planets which make them want to move in a straight line.
How does earth revolve in space?
the sun holds the planets in orbit.
What are the large objects in space that orbit a star such as the sun?
The answer is planets.
Why do the plantes orbit the sun?
why do the PLANETS orbit the sun? Because of gravity, the sun has loads of gravity so it holds all the planets in space.
What outside force prevents the planets from moving in a straight line into space?
The gravitational force produced by the sun keeps the planets in orbit around it. This force pulls the planets toward the sun, creating a continuous circular motion rather than a straight line out into space.
Dose all the planets orbit the sun?
All the planets in our solar system orbit our sun. Recently other suns, far out in Space, have been discovered to have their own planets.
What happens when the planets stop moving?
If the planets were to suddenly stop moving, they would no longer orbit the sun due to the lack of gravitational pull. Without their orbital motion, the planets would likely drift off into space in a straight line until they either collided with something or were gravitationally attracted to another object. This scenario is purely hypothetical as the laws of physics dictate that the planets will continue to orbit the sun.
Are the eight planets under the sun or above it?
Neither. The eight planets orbit the sun, but in space there is no "under" or "over."
What happen to the planet's orbit if there is no sun?
Without the sun's gravity to hold the planets in orbit, they would no longer be bound to their current paths and would drift off into space. The absence of the sun's warmth and light would also have profound effects on the planets' atmospheres and surfaces, potentially leading to freezing temperatures and inhospitable conditions.
What would happen to the planets if you took away the sun's gravity?
If the sun's gravity suddenly disappeared, the planets would no longer be held in orbit around it. They would continue moving in a straight line due to their inertia, leading them to drift off into space in their respective directions. The solar system as we know it would cease to exist.
What would happpen to a space vehicle in orbit around Earth if it sped up?
If its speed was greater than the pull of gravity - it would simply leave orbit and drift off into space.
What is the difference between a planet and other space objects?
To qualify as a planet, a body has to be approximately round, it has to orbit the sun and it has to have cleared its orbit of all other objects - so that at that distance from the sun, there are no other sizable bodies. Some dwarf planets, like Pluto, fulfill the first two requirements, but not the last one, this is why they are deemed dwarf planets rather than planets.
