Kepler's Laws of Planetary Motion:
1] Each planet moves in an elliptical orbit with the sun at one focus
2] The line form the sun to any planet sweeps out equal areas of space in equal time intervals
3] The squares of the times of revolution (days, months or years) of the planets are proportional to the cubes of their average distances from the sun.
The ellipses were discovered in the 17th century by one Johannes Kepler. Johannes Kepler discovered that the orbits along which the planets travel around the Sun are ellipses with the Sun at one focus, in his first law of planetary motion.
Kepler's first law says Neptune has an elliptical orbit with the Sun at one focus. The same goes for the other planets.
Kepler's law that describes how fast planets travel at different points in their orbits is called the Law of Equal Areas. This law states that a planet will travel faster when it is closer to the Sun and slower when it is farther away, so that the area it sweeps out in a given time is the same regardless of its distance from the Sun.
An orbit with a large semimajor axis will have the longest period according to Kepler's third law. This means that an orbit with the greatest average distance from the central body will have the longest period.
Kepler did not discover ellipses. In 1605 he discovered that the orbits of the planets were ellipses rather than perfect circles.

Ellipses are a scientific word for the shape of an oval. for example the planets orbits are ellipses.
Kepler's Third Law, also known as the Harmonic Law, states that the square of the orbital period of a planet is directly proportional to the cube of the semi-major axis of its orbit.
Ellipses are not circles.
Johannes Kepler was the person who first showed that planetary orbits are ellipses. His work, published in 1609, is known as Kepler's first law of planetary motion.

Kepler's law that describes how fast planets travel at different points in their orbits is called the Law of Equal Areas. This law states that a planet will travel faster when it is closer to the Sun and slower when it is farther away, so that the area it sweeps out in a given time is the same regardless of its distance from the Sun.
Kepler's Law: "The orbits of the planets are ellipses with the Sun at one of the foci."
A consequence of Kepler's Second Law (law of equal areas) is that a planet moves faster in its orbit when it is closer to the Sun and slower when it is farther away. This results in an uneven distribution of orbital velocities throughout the planet's orbit.
An orbit with a large semimajor axis will have the longest period according to Kepler's third law. This means that an orbit with the greatest average distance from the central body will have the longest period.
