Keplers laws.
Kepler deduced that the planets orbit about the sun in an elliptical pattern described by the mass at one focus of two. When the planet (or any satellite for that matter) is closer to the extreme of the ellipse closer to the "real mass" focus, it will travel faster through space, however, when going about the opposite extreme, it will travel slower. The ratio at which this happens is difficult to describe but I will say that the planet will cover the same amount of "area" with the "massive" focus as a center as anywhere else.
The reason that it is an ellipse and not a circle? well, the chances of a stranded loner mass enters the gravitational field of a greater mas at just the right angle and a just the right speed are very small. An ellipse is simply easier to manage, at least for nature.

Who introduced elliptical orbits?
It was Kepler who discovered that the planets orbits are elliptical.
Planets revolve around the sun along?
In one word 'YES'. The paths that you describe are the planets orbits. These orbits are shaped like 'Ellipsoids'., that is an ellipse that doesn't quite close-up , but overloops with every circuit. The Sun lies not at the centre of the ellipsoid, but at one of the foci. As a consequence planets following their orbits paths speed up (Nearest the Sun) and slow down (Furthest from the Sun).
What has elliptical orbits?
As an elliptical orbit is any orbit that isn't perfectly circular, everything has an elliptical orbit. The planets Mercury and Pluto have the most elliptical orbits of the planets, and are easily seen to be oval shaped. Comets also have highly elliptical orbits.
What are the paths called that planets orbit on around the sun?
They are orbits and they are elliptical in shape. So the answer could be "orbits" or it could be "ellipses".
What is path that a planet travels on around the sun called?
Planets have elliptical orbits around the sun.
What evidence do you have that the planets move in elliptical orbits around the sun and not in circular orbits?
Elliptical orbits of the planets around the sun actually match what we observe. Newton's Theory of Universal Gravitation states that planets will move around the sun in elliptical orbits.
Planets move around the sun in orbits?
elliptical
In what type of orbits do planets move around the sun?
elliptical
Do all planets have to be circle?
No, because all planets known have elliptical orbits.
Is the orbit of each planet a ellipse?
All the planets have elliptical orbits but Uranus and Neptune have slightly different orbits than other planets on solar system.
Who introduced elliptical orbits?
It was Kepler who discovered that the planets orbits are elliptical.
What are the planets orbits?
The planets orbits are the routes or paths that the planets follow around our sun. One orbit is one trip around the sun (one year).

His calculations showed that the planets revolve around the sun in elliptical orbits?
Kepler
Johnnas Kelpler discovered that the orbits in which planets move around the sun are?
Elliptical
What keeps planets in elliptical orbits?
Gravity and velocity (inertia) keeps planets in orbit around suns.
How do you use elliptical in a sentence?
The orbits of the planets around the Sun are not spherical as many people imagine but are in fact elliptical.
