Probably Hailey's Comet. Actually, all comets.
If you take a mechanical model of the solar system, grab the earth; then the sun will orbit it and the planets will "adopt" a elliptical orbit. However; observations of extra-solar system planets show that stars are stationary, except for a slight "wobble" as they ACTUALLY orbit their COMMON center of gravity which is VIRTUALLY near the star given it's having the bulk of the mass, thereby giving the impression of it being PERFECTLY stationary relative to a satellite. But; of the underlying physical mechanism whereby a larger object remains central there must be a "stay put" factor to it's superior "spinning power" even as a spinning top has the tendency to "stay put" whilst it is doing so. Whether this phenomena is describable in physics I don't know. Incidentally, the physics of the gyration of a spinning top, and also the similar precision of the equinoxes on earth is UNKNOWN and a great mystery in science.
I just found it , its called revolution
Orbital speed is determined by the mass of the body and the distance from the sun. Given its extreme distance, Pluto has the slowest orbit. However, Pluto is no longer considered a planet, but instead a planetoid. Therefore Neptune now has the slowest orbit.
The object you are referring to is a comet. Comets are composed of ice, dust, and rock, and they have long, elliptical orbits that bring them close to the sun at one end and far away at the other. When a comet approaches the sun, the heat causes its ice to vaporize, creating a glowing coma and often a tail of dust and gas pointing away from the sun.
In a lead atom, the number of electrons in each orbit are as follows: 2 electrons in the first orbit (closest to the nucleus) 8 electrons in the second orbit 18 electrons in the third orbit 32 electrons in the fourth orbit
A comet is an object that comes close to the sun in a highly elliptical orbit but can also be found far from the sun in its journey through space. Comets are composed of ice, dust, and rock, and as they approach the sun, they develop a glowing coma and tail due to the heat.

The orbit of Eris is 44° from the ecliptic.
Through gravitational pull. The largest object will have smaller objects orbit it (objects close in size will orbit each other, but no planet is close to the size of the sun)
This is an orbit.
a object orbit another object is called a what?
The distance of perigee is the point in an object's orbit that is closest to the center of the body it is orbiting around, such as a planet or a star. The distance of perigee varies depending on the specific orbit and the object in question.
Not quite. Forever is a long time! If the satellite is high enough to make air resistance irrelevant, it can stay in orbit for a long, long time. However, orbits do tend to decay eventually; an orbiting object will lose some energy through air resistance, and - in the very long term - through gravitational waves. It is also possible that an object that comes close to Earth changes the orbit of orbiting satellites.
A bound orbit is a closed path around the Sun where an object is gravitationally bound to the Sun, like the planets in our solar system. An unbound orbit is when an object travels past the Sun once and does not return, like a comet that enters the solar system from afar and leaves after its close approach to the Sun.
Planet Venus cannot leave its orbit by itself. A sufficiently close encounter with a object of sufficient mass will perturb its orbit. If the object is large enough and close enough, Venus (or any planet) could leave the orbit of the Sun.

For any planet, or indeed, for any object that orbits any other object, the pull of gravity is balanced by the centrifugal force created by the speed of the orbit, so, the stronger the gravitational attraction, the faster the orbit. Mercury orbits the sun very rapidly.
