The discovery that planets travel in elliptical orbits around the Sun was made by Johannes Kepler in the early 17th century. He formulated his laws of planetary motion based on the observational data collected by Tycho Brahe. Kepler's first law states that planets move in ellipses with the Sun at one of the foci, fundamentally changing the understanding of celestial mechanics.

What did Kepler demonstrate with planets revolutions around the sun?

Johannes Kepler discovered that planet orbits were elliptical and not circular.


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.


Are the orbit of planets circular and How may their path be best described?

No, the orbits of planets are not perfectly circular but are elliptical in shape. The path of planets around the Sun can be best described using Kepler's laws of planetary motion, which state that planets move in elliptical paths with the Sun at one of the foci of the ellipse.


Johnnas Kelpler discovered that the orbits in which planets move around the sun are?

Elliptical


Who discovered the elliptical path of the planets?

17th century astronomer Johannes Kepler discovered the elliptical shape of the planets' orbits around the Sun, which he described in his first law of planetary motion. Newton later explained this in his law of universal gravitation.


What is the shape of the orbits of the planets around the sun?

The planetary orbits of our solar system are considered "elliptical." This includes "circular" orbits, as a circle is a type of ellipse. In astrodynamics, an elliptical orbit and a circular orbit both fit into the description of a Kepler Orbit.


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 is the orital shape of the planets in our solar system?

The planets in our solar system have an elliptical (oval) orbit around the Sun. This orbital shape is a result of the gravitational forces between the planets and the Sun. Planets closer to the Sun have shorter and more circular orbits, while those farther away have longer and more elliptical orbits.


Who is the astronomer who discovered planets follow elliptical orbit?

Johannes Kepler, a German astronomer, discovered that planets follow elliptical orbits around the Sun, rather than perfect circles. This discovery is known as Kepler's first law of planetary motion and was a significant advancement in our understanding of the solar system.


How is the orbit of the earth around the sun shaped?

All planets in our solar system, including the the Earth have an elliptical orbit around our Sun. In Earth's case, the orbit is nearly circular.


Who discovered that the orbits in which the planets move around the Sun are elliptical?

Johannes Kepler discovered that the orbits of planets around the Sun are elliptical in shape. Kepler's work on planetary motion led to his three laws of planetary motion, which revolutionized our understanding of the solar system.


Johannes Kepler discovered that the path that the planets followed what kind in shape?

Johannes Kepler discovered that the path that planets follow around the sun is an elliptical shape. This is known as Kepler's First Law of Planetary Motion.
