well for starters, stars don't orbit planets. Planets orbit stars, but some stars don't have planets that orbit them.
Gravity counteracts this inertia, usually the gravity of a body much larger than itself.
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.
We all die
if our planet Earth had a larger orbit than it does today, the temperature would be dramatically different and most life on the planet would most likely die out from the extreme cold.
All known moons. But in theory, there could be a moon orbiting a larger moon, if the large moon was far enough away from the planet.
A planet year is defined as the time it takes a planet to make one complete revolution in its orbit around the sun. The farther away from the sun a planet is, the larger its orbit. The larger its orbit, the longer (more days) it takes to go around the sun. Thus, the farther away a planet is from the sun, the longer its year will be.
These are known as moons. Natural satellites that are in orbit around a larger planet.
YES Mercury is the closest planet to the Sun The further away you are the larger the orbit I think it must be Mercury because it is the closest planet to the sun
Jupiters orbit is a imaginary circle that the planets circle around that is how we count years.
That sketchy description could be applied to a planet, a satellite, a moon, an asteroid, a comet, a meteoroid, or even an electron.
The path that the planet follows is simply called the orbit. Orbit can mean 'to revolve around the sun' or it can be referred to as the path itself, e.g. 'Earth is following its orbit.'
No. For one thing, stars are actually much larger than planets. Planets orbit stars such as the sun. It is possible, however, for the orbit of a planet to decay, in which case the planet will eventually fall into the star.
