Centripetal force, which keeps planets in orbit around the sun, does not require physical supplies but rather results from the gravitational attraction between the sun and the planets. This force is generated by the mass of the sun and the planets, along with their velocities. The balance between gravitational pull (centripetal force) and the planets' inertia allows them to maintain stable orbits. Essentially, the energy and mass of celestial bodies are the "supplies" that facilitate this gravitational interaction.
The unit of centripetal force is the Newton (N), which is the same as the unit of force in the International System of Units (SI).
The planets orbit the Sun in near-perfect circles, but they are actually ellipses. This is because that although the Sun contains much more mass than the planets in our solar system, the planets pull the Sun slightly, which by definition creates an elliptical orbit.
The force that keeps planets in orbit is gravity. Gravity is the attractive force that exists between two masses, such as a planet and a star, that causes them to be drawn towards each other. In the case of planets orbiting a star, gravity keeps the planets in their elliptical paths around the star.
The mutual, equal forces of gravitation between every pair of masses provide the centripetal force that maintains closed orbits.
The force of gravity between the planets and the sun keeps them in their respective orbits, maintaining their approximate distances from each other. This gravitational force acts as a centripetal force, balancing the planets' inertia and keeping them in stable orbits around the sun.
The gravitational force between planets supplies the centripetal force that causes them to orbit each other.
Centripetal force is the inward force required to keep an object moving in a circular path, and for planets, this force is primarily provided by gravity. As planets orbit a star, such as the Sun, the gravitational attraction acts as the centripetal force, pulling them towards the star while their orbital velocity keeps them in motion. This balance between gravitational pull and orbital speed allows planets to maintain stable orbits. Thus, centripetal force is essential for the dynamics of planetary motion in a solar system.

Centripetal force and Gravity
The centripetal force is supplied by the tension in a string, gravitational force, friction, or any force pointing towards the center of the circular motion that keeps an object moving in a curved path.
Centripetal force is a force that is required to exist to have a circular motion. Thus the centripetal force can be any force that is able to accomplish this task. Examples of centripetal forces are the gravitational force, the electromagnetic force, the frictional force, or the constraint forces. The centripetal force depends on the system that is involved in be in a spin of a rigid body, or of a planetary motion, etc. Each particular system that requires a rotation or a spin needs to have a corresponding centripetal force.
The forces of attraction between the sun and each planet are gravitational forces, and they're both centripetal forces.
friction
The unit of centripetal force is the Newton (N), which is the same as the unit of force in the International System of Units (SI).
The gravitational force between the sun and the planets keeps them in orbit. This force acts as a centripetal force that continually pulls the planets towards the sun, keeping them in a stable orbit. The balance between the planet's velocity and the gravitational force determines the shape and size of their orbits.
Centripetal force is a force that makes a body follow a curved path. An example of centripetal force is gravity making something in space orbit Earth. Mud flying in circles from a tire going down the road is centripetal force.
