The Sun maintains equilibrium through a balance between gravitational forces and the outward pressure created by nuclear fusion in its core. Gravity acts to pull the Sun's mass inward, while the energy generated from fusion reactions converts hydrogen into helium, releasing immense amounts of energy that create radiation pressure pushing outward. This delicate balance ensures that the Sun remains stable over long periods, preventing it from collapsing or expanding uncontrollably.
The sun is held in place by its own gravity, which is balanced by the outward force of the nuclear fusion reactions happening in its core. This dynamic equilibrium keeps the sun stable and prevents it from collapsing or drifting away.
because the earth and the sun is not in the thermal contact with each other that is why the earth & the sun is not in thermal equilibrium.
While the earth and the sun are roughly at steady state (the output of the sun stays fairly constant and the earth absorbs the energy from it at a fairly constant rate) they are not in equilibrium. To be at equilibrium, they would have to be sending out and receiving equal amounts of energy and mass. The sun sends out far more energy than the earth as well as dumping a lot more mass, in the form of "solar winds" than the earth ever does - thus they are not in equilibrium.
Planets maintain their specific distances from the Sun due to the balance between gravitational forces and their orbital velocities. The Sun's gravity pulls planets inward, while the planets' momentum keeps them moving forward in their orbits. This delicate equilibrium results in stable orbits, as described by Kepler's laws of planetary motion. Additionally, the initial conditions of the solar system's formation influenced the distances and speeds of the planets.
The force is gravity. Gravity is the force of attraction between two objects with mass, and the sun's gravitational pull keeps the members of the solar system bound to it, causing them to orbit around the sun.

You mean 'keeps in the orbit of the sun? Gravitational force of attraction keeps the earth going around the sun.
Dynamic equilibrium.
The Earth is not in thermal equilibrium with the Sun because the Earth receives energy from the Sun in the form of sunlight but also radiates energy back into space in the form of infrared radiation. This continuous exchange of energy maintains a temperature difference between the Earth and the Sun, preventing thermal equilibrium. Additionally, factors such as the Earth's atmosphere, albedo, and distance from the Sun also contribute to the lack of thermal equilibrium.
Actually, it's the gravity of the sun that keeps the planets in orbit around it. The force of gravity between the sun and the planets causes them to be pulled towards the sun, while their momentum keeps them moving in a circular or elliptical path.
In the Sun, the forces of gravity pulling inward are balanced by the outward pressure from nuclear fusion reactions in the core. This equilibrium maintains the Sun's stable size and temperature.
The sun's gravitational pull keeps the earth in orbit around it.
The largest force that keeps the Earth circling the sun is gravity. Gravity is the force of attraction between the Earth and the sun that keeps the Earth in its orbit.
