No. An object of just about any size can orbit at any distance.
NO, the orbit of any planet or moon is determined by the size of the two objects involved (example: the Earth and the Sun) and the distance between those two objects: the closer the objects are to each other and the bigger one of the objects is, the stronger the gravitational pull ( large objects have stronger forces on other smaller objects). The orbit of a planet has nothing to do with the Sun's heat.
Yes. Earth is closer to the Sun than Mars, so it will have a smaller orbit.
Moons.
Planets orbit stars, not other planets. A planet-like object that orbits a planet is a moon.
the closer the smaller orbit (a year is one complete orbit) so the year is smaller
Asteroids are objects smaller then planets that orbit the Sun. Meteorites are (usually) smaller objects that enter the atmosphere and reach the ground.
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)
The sun is much bigger than planets and has more mass, so it also has more gravitational pull. Objects in space with a greater gravitational pull can keep smaller objects in orbit.
Many smaller objects cross Eris' orbit, so it does not dominate its orbital path. An object must clear its orbit of other objects to be considered a planet.
most of the objects in our solar system orbit what celestial body
no. in solar system, closer you are to sun, the smaller the orbit size.
There are no known objects that orbit the sun closer than Mercury! though there mite be some small asteroids not visible.
