What celestial bodies implement motion along the curves of conic sections?

Elliptical motion – planets, periodic comets, asteroids, natural and artificial satellites of planets. A circle is a special case of an ellipse; planets and satellites are known that move in elliptical orbits with a very small eccentricity, for example Venus. Comets coming from interstellar space or changing their orbits under the influence of massive cosmic bodies can move along parabolic and hyperbolic orbits.
The Sun and other stars move in elliptical orbits around the center of the Galaxy.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
