Answer» Correct Answer - Option 4 : Orbit
The correct answer is Orbit. - An orbit is the path of a planet around the sun.
- Kepler's Law of Planetary Motion states that planets revolve in an elliptical orbit.
- Kepler’s Laws of Planetary Motion:
- All planets move around the sun in elliptical orbits, with the sun being at rest at one focus of the orbit.
- The position vector of the planet with the sun at the origin sweeps out equal area in equal time.
- The square of the period of revolution of a planet around the sun is directly proportional to the cube of the main distance of the planet from the sun.
- Our galaxy is called the Milky Way (or the Akashganga) and it contains about 300 billion stars and one of these is our sun.
- Planets and other objects go round the sun and make up the solar system with the sun at the center.
