gravity
The two forces that result in the orbit of a planet are gravitational force, which pulls the planet towards the center of the star it is orbiting, and the planet's tangential velocity, which keeps it moving in a curved path around the star. These two forces are perfectly balanced in a stable orbit.
The force that pulls the material of a nuclear explosion back into a star is gravity. Gravity is the attractive force between objects with mass, and in the case of a star, it is the force that keeps the star's material gravitationally bound together despite the energy released in a nuclear explosion.
Doubling the mass of the star would increase the gravitational attraction between the star and its planet. The force of gravity is directly proportional to the product of their masses, so doubling the mass of the star would double the gravitational force between them.
Orbital speed is the velocity required for an object to stay in a stable orbit around another body, like a planet or a star. It is determined by balancing the gravitational force pulling the object towards the center with the object's inertia carrying it forward. The speed needed for orbit depends on the mass of the central body and the object's distance from it.
This force is called gravity, and it is due to the mass of the planet or star creating a gravitational field. The gravitational force pulls objects toward the center of the celestial body, causing them to accelerate downward.

The gravitational force between two masses acts along the line that joins their centers of mass.

the sun's gravity pulls the planets towards it but the other planet's gravity helps keep the planet not get sucked towards the sun. With gravity working this creates the planet to orbit the sun

a planet has it's own weak gravity that pulls the star it's orbiting as it orbits, as the star gets pulled around by the planet, scientist on Earth see the star wobbling, and then they know there is a planet!
Gravity is the force that counteracts a planet's inertia and keeps it in its orbit. The gravitational force between the planet and the star it orbits causes the planet to continuously fall towards the star while simultaneously moving tangentially at a sufficient speed to remain in a stable orbit.
All of the forces act to make a star. Gravity is the main force, which pulls everything together, and the other forces ignite the star.
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 effect on the star is usually quite small, but the force is "gravity".
