In the case of our solar system, each of the eight major planets are sufficiently large in mass to have absorbed or expelled other matter from their orbital paths; this has precluded the formation of multiple planets in each orbit.
Indeed, the current definition of a "planet" used by the IAU requires a body to have done this in order to be called a "planet." Other bodies, such as asteroids and dwarf planets, do share their orbits in whole or in part with other bodies.
Some have suggested that the Moon is so large in relation to the Earth that the Earth and Moon could be considered a double planet system rather than a planet/satellite system. (The same was true of Pluto and Charon before Pluto was redefined as a dwarf planet.) This is not a widespread view, but in other solar systems double planets are thought to be quite common. Double planets orbit each other while orbiting their central star(s). In this situation, both planets would share an orbit around the star.
There are small bodies called "Trojan asteroids" that share an orbit around the Sun with Jupiter and Saturn. Jupiter's and Saturn's gravity keep these asteroids in fixed positions.
What else can I help you with?
What planets orbit Saturn?
No planet orbits around Saturn because planets only orbit around a star like our Sun. And Saturn isn't a star, it's a planet.
What makes planets stay in orbit around the sun?
Each planet stays in its orbit because it is being pulled constantly by the Sun's gravity. The planet does not fall into the Sun because it has a velocity taking it along its orbit, so the effect of gravity is only to make the planet's path curve towards the Sun all the time.
Is the sun the only planet in the universe?
No! its not a planet it is a huge ball of gas called a 'Star' which the planets orbit around.
What planet can orbit the sun four times in the amount of time it takes earth to orbit the sun once?
Mercury. Its the closest planet to the sun and only takes 88 days to orbit once around the sun.
All planets complete one in a year?
This statement is not accurate. A year is the time it takes for a planet to orbit around the sun. Each planet has a different orbital period, so their years vary in length. For example, Earth takes about 365 days to complete one orbit, while Venus only takes about 225 days.
Is the moon a outer planet or inner planet?
Neither. Except perhaps in a poetic sense. Planets orbit around the sun. Moons orbit around planets. The earth has only one and we call it "the moon".
What planet having three satellites sharing the same orbit?
Saturn has at least two natural satellites (moons) sharing the same orbit. There may be three altogether, but I only know of two.
Is there any planet that does not revolve in oval orbit?
A planet revolving around a single star will always have a relatively circular or ovular path. The only time the orbit would be different would be if the planet was being pulled by the gravity of multiple stars.
What planet has not completed an orbit since its discovery?
The planet Neptune has not completed a full orbit since its discovery in 1846. It takes Neptune approximately 165 Earth years to complete one orbit around the Sun, so it has only completed a fraction of its first orbit since its discovery.
How do planets only orbit around the sun and not go everywhere in space?
Planets orbit around the sun due to the gravitational force between the sun and the planet. The planet's velocity and distance from the sun are balanced in such a way that it follows a stable orbit path. This balance allows the planet to remain in a relatively stable position around the sun without drifting off into space.
What is earthes orbit?
An orbit is the path a planet takes around the sun. Earth's orbit is an ellipse. It takes the Earth one year to travel along the elliptical path around the sun.
What is the only planet to orbit the sun on its side?
Uranus.
