Johannes Kepler was born on December 27, 1571. He died on November 15, 1630. Kepler came up with the Laws of Planetary Motion. His first law illustrates how the orbit of each planet is an ellipse, not a perfect circle. His second law states that the speed at which a planet moves is greater the closer … Continue reading Historical Astronomers in Context → Continue reading →

Johannes Kepler: December 27, 1571 – November 15, 1630 Johannes Kepler made important contributions to astronomy, primarily from his studies of celestial mechanics. From his calculations and Tycho’s observations, Kepler developed his three Laws of Planetary Motion. First, “Planets move in ellipses with the Sun at one focus.” Second, “The radius vector describes equal areas … Continue reading Historical Astronomers in Context Continue reading →

Kepler, during his lifetime from December 27th, 1571- November 15th, 1630,  made incredible contributions to the field of astronomy. His most famous and impactful contributions are certainly his observations regarding the motion of planets, which have been immortalized as Kepler’s Laws. His discoveries about planetary motion stated that planets move in elliptical orbits, they sweep out […] Continue reading →

Living the fast life: Kepler-70b

Posted on April 12, 2016 by d51blog

The Kepler spacecraft (which was feared lost earlier this week) has discovered a veritable treasure trove of exoplanets over its seven year mission. Some of these planets may even be habitable. Kepler-70b is decidedly not one of them. Kepler-70b is the closer of two terrestrial planets to KOI-55, a subdwarf star which was once a red giant. […] Continue reading →

Celestial NASCAR: Kepler’s Laws of Planetary Motion

Posted on February 15, 2016 by d51blog

Before 1609, the scientific consensus in Europe was that the planets orbited the Earth in perfect circles; even dissenting views such as Copernican heliocentricism relied upon perfect circles to guide objects around the Sun. Johannes Kepler, however, motivated by minute errors in planetary distances discovered when attempting to construct Copernicus’ model, revolutionized astronomy with his laws of […] Continue reading →

Kepler was the first astronomer to accurately describe and define the orbits of the planets around the sun. Kepler was alive from 12/27/1571 – 11/15/1630.  He was able to develop 3 laws of planetary motion.  These laws of planetary motion laid the ground work for other astronomers and scientists to make some of the greatest […] Continue reading →

Historical Astronomers in Context: Johannes Kepler

Posted on February 9, 2016 by nickwtheastronomer

Who is Kepler Johannes Kepler’s most renowned contribution to astronomy was his development of the three laws of planetary motion. These three laws correctly defined the elliptic shape of all planetary orbits, established the equal area-equal time interval concept of solar radii, and equated the period of orbit with the size of the orbital elliptic […] Continue reading →

“O, swear not by the moon…”

Posted on February 9, 2016 by Gabi Grys

Johannes Kepler made important contributions to astronomy through his discovery that planetary orbits are ellipses. Kepler came to this conclusion after several years of painstaking effort trying to make sense of all the observations of his former master Brahe. Kepler also proposed three laws of planetary motion as a summary of his findings. Kepler was […] Continue reading →

Johannes Kepler in Context

Posted on February 9, 2016 by annamcc9

Johannes Kepler (December 27, 1571 – 1630) was important to astronomy because he developed three laws of Planetary Motion. They were a result of analyzing observations made by Tycho Brahe concerning the orbit of Mars. The laws are: Planets move in ellipses with the Sun at one focus, the radius vector describes equal areas in […] Continue reading →
