The discovery that planets travel in elliptical orbits was made by Johannes Kepler. In the early 17th century, Kepler formulated his First Law of Planetary Motion, which states that planets move around the Sun in elliptical paths, with the Sun at one focus of the ellipse. This groundbreaking work built upon the precise observational data collected by Tycho Brahe. Kepler's laws significantly advanced the understanding of planetary motion and the heliocentric model of the solar system.

Kepler discovered that the planets orbit the Sun in elliptical shapes. This means that their orbits are not perfect circles, but instead are stretched out ovals with the Sun located at one of the foci of the ellipse.

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.

Kepler found the orbit of the planets were?

Kepler found that all planets move in elliptical orbits, with the sun being at one focus. Kepler also announced that the speed an object traveled along it's path varied according to how close the object was to the sun. He also announced that the larger a planet's orbit, the slower it travels.


What shape do planets trace as they orbit around the sun?

Planets orbit the sun in the shape of an ellipse, which is an elongated circle similar to an oval. When it was first discovered that the Sun is the center of the solar system, it was thought that all the planets had a circular orbit, but the calculations didn't fit.
