With an open orbit, the object never returns. Examples would be a satellite in an unstable (open) orbit crashing down on Earth or a passing comet on a hyperbolic orbit which will leave our solar system (ejection loss).
Closed orbits are the stable, planet-like orbits where objects return in a predictable manner.
An orbit in which a planet (for example) eventually returns to its previous position. An orbit which is repeated over and over again. The shape is circular or elliptical.

Ellipse
No. The truth is the exact opposite. Every object in a closed orbit around the sun ...every planet, asteroid, periodic comet, etc. ... has an elliptical orbit.
It's Venus at the moment, but depending on positions in orbit sometimes mars or mercury could be closer.
Any comet visible from earth is in orbit around the sun. If the orbit is closed (elliptical), the comet will return after some period of time. If the orbit is open (parabolic or hyperbolic), the comet will escape the solar system and never return to the neighborhood.
The sun is a star.It's the only self-luminous body in the solar system.The gravitational force of mutual attraction between the sun and everything in a closed orbitaround it is what makes the closed orbits possible.One focus of the elliptical path of everything in closed orbit around the sun is at the center of the sun.The orbits of the planets are so nearly circular (small eccentricity) that the center, as well as both foci,of every planetary orbit is inside the sun. This isn't true of most repeating cometary orbits.
All closed gravitationalorbitsare ellipses.So the shape of an asteroid's orbit iselliptical.
The Earth's moon orbits in an ellipse, just like every other closed gravitational orbit.
To orbit the object.
All closed gravitational orbits are ellipses.
No. Every closed orbit (around and around and around) is an ellipse. Every open orbit (swish by one time and never return) is a hyperbola. The one that's exactly precisely on the dividing line between closed and open is a parabola.
No force is necessary to keep a moving object in motion. But if you want it tofollow a curve, such as for example a closed orbit, then that takes force. Theforce that keeps Neptune in its closed orbit is the same force that keeps everyplanet, moon, comet, and asteroid in its own closed orbit around its own centralbody. It's the force of gravity.
orbit ? one year ?
Ellipse
Yes, every closed orbit is an ellipse. Circles are "perfect" ellipses, but no natural orbit could be perfectly circular.
Orbit, if it is closed otherwise one might call it a trajectory.
A satellite in a closed orbit has the greatest speed when it's closest to the planet, and the lowest speed when it's farthest from the planet.
