None do. If the forces on a planet were balanced, then it would take off in
a straight line at constant speed, not remain in orbit. The only force acting
on a planet is the gravitational one, that attracts the planet toward the sun.
Fortunately, that's the only force required to keep the planet in orbit.
Gravity, caused by the planets' mass, pulls them towards the Sun, while their inertia, resulting from their initial velocity, keeps them moving in a straight line. The combination of these two factors results in the planets moving in elliptical orbits around the Sun.

Why don't planets collide?
Planets do not collide because of gravitational forces that keep them in stable orbits around the sun. These gravitational forces cause planets to travel in predictable paths without intersecting each other's orbits. Additionally, the vast distances between planets in our solar system help prevent collisions.
What factors influence the stability of planetary orbits within a solar system?
The stability of planetary orbits within a solar system is influenced by factors such as the gravitational pull of the central star, the mass and distance of the planets, and any external forces from nearby celestial bodies. These factors interact to determine the overall stability and structure of the planetary orbits.
Why the planets keeps on their orbits?
The planets continue on their orbits due to a balance between the gravitational force pulling them toward the sun and their velocity providing the necessary centripetal force to keep them in motion. This balance creates a stable orbit as the planets move around the sun.
What two forces work together to keep the planets in orbit around the sun?
Gravity and inertia work together to keep planets in orbit around the sun. Gravity from the sun pulls the planets towards it, while the planets' inertia keeps them moving forward in their orbits.
What are two things that work together keeping planets in their orbits around the sun?
Gravity and the laws of motion, specifically Newton's laws of motion, work together to keep planets in their orbits around the sun. Gravity from the sun pulls the planets towards it, while the inertia of the planets moving in a straight line causes them to travel in an elliptical orbit around the sun.
List two factors that Newton showed combined to keep the planets in their elliptical orbits?

When will planets bump into other planets?
Planets in our solar system are on stable orbits and are not expected to collide with each other. However, in the broader universe, planet collisions can occur when two planetary bodies are on a collision course or if a disruption in their orbits leads to a collision. The likelihood of such events depends on various factors, including the density of objects in space and their trajectories.
How does gravity keep planets and other objects in the Solar System in orbits?
easy gravity :)
How can the planets orbit the sun?
It is the natural tendency for an object in motion to keep moving at the same speed in a straight line. Meanwhile gravity is trying to pull each planet toward the sun. The two forces combine to keep the planets in their elliptical orbits. They have enough forward momentum to keep them from falling into the sun, and they have enough pull from the sun to keep them from following a straight path out of the solar system.
What factors keep the planets in orbit?
Gravity and inertia
What holds all the planets in order?
Gravitational force is what holds all the planets in their orbits around the sun. This force is determined by the mass of the objects and the distance between them. The gravitational pull of the sun keeps the planets in their respective orbits.
What 2 forces combine to keep a planet in orbit?
Gravity and inertia combine to keep a planet in orbit around a star. Gravity pulls the planet toward the star, while the planet's inertia (its tendency to continue moving in a straight line) causes it to move forward, resulting in a stable orbit.
What keeps a planet in its constant orbit?
There are two factors that are balanced just right to keep the planets in their orbits; the tangential velocity, and the gravity. The planets have a tangential velocity, they are speeding along sideways relative to the sun. If there was no gravity, this velocity would take the planets away from the sun, but the sun has a huge gravitational force which counteracts this effect. The suns gravitational force is constantly attracting the planets in, against this tangential velocity. If the planets were to slow down, then they would eventually spiral into the sun, but in space there is no drag, so the planets maintain their speed and their orbits.

Each planet moves around in the sun in?
orbit. The force of gravity from the sun holds the planets in their orbits, while the planets' velocity and inertia keep them moving in a curved path around the sun. This balance between gravity and inertia allows the planets to move in stable orbits.
Why the planets keeps on their orbits?
The planets continue on their orbits due to a balance between the gravitational force pulling them toward the sun and their velocity providing the necessary centripetal force to keep them in motion. This balance creates a stable orbit as the planets move around the sun.
