Unfortunately, you neglected to include the list of allowable choices that "follows"
the question. Still, I know the answer.
The force that keeps comets in closed orbits around the sun is the one that has
the same effect on the planets; gravity. The only difference is that the orbits
of the long-term comets are much more 'eccentric' (long and skinny) than those
of the planets, so they have much shorter minimum distances from the sun, and
much longer maximum distances, than planetary orbits have.
So, the correct awnser is Gravity.
The moon orbits the Earth due to the gravitational pull the two bodies have on each other.
Planets, moons, asteroids, and comets are some examples of large objects that move around a star, such as the Sun in our solar system. These objects orbit the star due to gravitational forces and can vary in size and composition.
The force that causes the formation of the solar system is primarily gravity. Gravity pulls particles and gases together, forming a spinning disk that eventually condenses into the Sun and planets. Other forces such as electromagnetic and nuclear forces also play a role in the formation process.
The two competing forces in a star are gravity, which tries to collapse the star under its own weight, and nuclear fusion, which generates energy and causes the star to expand outward. These forces balance each other to maintain a stable, long-lived star.
The rings of gas giants are believed to have formed from the gravitational forces acting on debris such as dust, rocks, and ice particles in orbit around the planet. This debris may have originated from the planet's moons or from collisions with asteroids or comets. The rings are maintained by a delicate balance between gravitational forces and collisions that continually fragment and replenish the ring material.
Most "asteroids" are in orbit around the Sun, unless disturbed by gravity or collisions. Comets may orbit the Sun regularly, or be drawn in from the outer solar system and pass by the Sun on their way back out (hyperbolic comets).
Both comets and Earth are celestial bodies located in our solar system. Comets are composed of ice, dust, and rocky material, similar to the materials present on Earth. Additionally, both comets and Earth experience gravitational forces from the sun that affect their orbits and movements.
Comets can be captured by planets, ejected from the solar system, or collide with a celestial body such as a planet or star. Some comets may break apart or disintegrate due to the effects of gravitational forces and their volatile nature.
There is none. Both comets and planets are in free-fall, moving in accordance with their inertia and the gravitational forces between the Sun and the planet or asteroid.
Comets. The Oort Cloud is a vast region of space beyond the orbits of Pluto and the other outer planets where many comets are believed to originate. These icy objects can be pushed into the inner solar system by gravitational forces and become visible as comets when they approach the Sun.
Comets do not fall. They orbit around the Sun in elongated orbits, with their paths often bringing them close to the Sun before they swing back out into the farther reaches of the solar system. This motion is due to the gravitational forces acting on the comet from the Sun.

Friction is the force that causes static charge
unbalenced
I would think by getting pulled into gravitational forces and being swung right back out into space.
There are two forces that causes an airplane to be airborne. They are Thrust and Lift. The other two forces resists the airplane's flight. They are Gravity and Drag.
