Question+4

What is an orbit? How many times does each planet orbit the sun in one Earth year?

In physics an orbit is the gravitationally curved path of an object around something in space for example a gravitational orbit of a planet or point near to a star.

Current understanding of the mechanics of orbital motion is based on Albert Einstein's general theory of relativity, which accounts for gravity as due to curvature of space-time , with orbits following geodesics; though in common practice an approximate force-based theory of universal gravitation based on Kepler's laws of planetary motion is often used instead for ease of calculation  I think that most of space is quite intresting but some parts can be boring and you can learn alot like i didn't know that an orbit had anything to do with gravity or even what an orbit is and i have learnt so much about the planets and you'll never know what they will find next. This is how long it takes for each planet to circle the Sun.
