Johannes Kepler was a German mathematician and astronomer who discovered that the Earth and planets travel about the sun in elliptical orbits. He gave three fundamental laws of planetary motion. He also did important work in optics and geometry.

Did Johannes Kepler discover Kepler planets?

No, Johannes Kepler is best known for describing the laws that dictate how orbits work. The Kepler planets were discovered by the Kepler telescope, a spacecraft named in his honor.


How was the planet Kepler 22b named?

Kepler-22b was given its the designation Kepler as it is one of many planets discovered by the Kepler observatory. The 22b refers to it being the innermost (and only known) planet orbiting the star Kepler-22.


Who is known for discovering that the orbit of the planets were elliptical?

Kepler


Who was responsible for three laws that explained the orbit s of planets?

Johannes Kepler was responsible for the three laws of planetary motion, known as Kepler's Laws. These laws describe the motion and orbits of planets around the Sun.


The fact that each planets orbit is an ellipse was discovered by?

Johannes Kepler discovered that planets orbit the Sun in ellipses with varying eccentricities in the early 17th century. This became known as Kepler's first law of planetary motion and revolutionized our understanding of planetary orbits.


Who is responsible for developing the three laws of planetary motion?

Johannes Kepler is responsible for developing the three laws of planetary motion, which describe the motion of planets around the Sun. These laws are known as Kepler's Laws of Planetary Motion and were published between 1609 and 1619.


What did Kepler realize about the orbit of Mars?

Johannes Kepler realized that the orbit of Mars is an ellipse with the Sun at one of the foci. This was one of his three laws of planetary motion, known as Kepler's First Law.


Does Kepler 22b has stronger or weaker gravity than earth?

As of 2014, not enough is known about Kepler 22b. Specifically, its mass is not known; therefore, its surface gravity can't be calculated either.


What is the biggest planet in the milky way galaxy that is known?

The Kepler project to find planets will continue to grow their database of confirmed planets. As of Dec 5, 2011 the largest are: by mass = Kepler 14b by radius = Kepler 17b by density = Kepler 22b


Who discovered the three principals of planetary motion?

The laws are known as Kepler's Laws after German mathematician and astronomer Johannas Kepler (1571-1630).


Who was the brilliant student of Tycho Brache that formulated the three laws of planetary motion?

No. Kepler discovered the laws using Tycho Brahe's data.


Did Kepler accurately described the motions of all the known planets?
