SOLAR SYSTEM

Detailed explanation-1: -Knowing then that the orbits of the planets are elliptical, johannes Kepler formulated three laws of planetary motion, which accurately described the motion of comets as well. Kepler’s First Law: each planet’s orbit about the Sun is an ellipse. The Sun’s center is always located at one focus of the orbital ellipse.

Detailed explanation-2: -An ellipse is a circle which has been squashed or flattened a bit. All 8 planets in our Solar System travel around the Sun in elliptical orbits. Not all ellipses are the same. The ‘eccentricity’ of an ellipse tells us how flattened (or how elliptical) it is.

Detailed explanation-3: -That’s essentially how objects in orbits work: as they move closer to the body they orbit, they accelerate faster and faster. Our penny will get so fast that, once it comes around the planet, it will be flung very far away, which will then slow it down. This is what creates an elliptical orbit.

Detailed explanation-4: -The orbit of a planet is elliptical in shape with the Sun at one of the foci. This is the statement of Kepler’s first law. In fact, this is true for all heavenly bodies.
