Why are the planets move around the sun?
A circular motion about an external point, e.g. the Earth about the Sun, is called an orbit or more properly an orbital revolution. The Earth completes one orbital revolution around the Sun in 365 days 5 hrs. The motion of the Earth about the Sun is seen as an apparent annual motion of the Sun along the ecliptic. A large number of astronomical observations of the positions of the Sun and other solar system objects have been made and are being made continuously. This information is required to determine the nature of the motion of the Earth about the Sun. Observations are analyzed using the mathematical methods of celestial mechanics to provide improved estimates of the motions of the solar system objects in the future and to describe the past motions of the objects. The description of the apparent motion of the Sun in the sky provides the determination of the orbit of the Earth. The eccentricity of the Earth’s orbit can be accurately determined from the variable speed of the Sun’s appa
it is a combination of gravity and momentum in a constant equilibrium the gravitational force holding the planets in their elliptical orbit does not exceed the momentum of the planets themselves causing us to basically “fall towards the sun, and miss” the planets are constantly falling towards the sun but our momentum is constantly pushing away causing the oval like shape we fall at the sun miss then turn around and fall back at the sun and miss again that is how the planets orbits work
First of all, saying the planets go around the Sun is just another way of saying the planets are in orbit around the Sun. A planet orbiting the Sun is like the moon or a NASA satellite orbiting Earth. Now why does a planet orbit the Sun and not the Sun orbit the planet? The lighter object orbits the heavier one, and the Sun is, by far, the heaviest object in the solar system. The Sun is 1000 times heavier than the largest planet, Jupiter (which also happens to be my favorite planet), and it is more than 300,000 times heavier than Earth (another planet I am very fond of).
