What is the proof of Kepler's first law and how does it contribute to our understanding of planetary motion?
Kepler's first law states that planets move in elliptical orbits around the sun, with the sun at one of the foci. This law was proven through observations and mathematical calculations by Johannes Kepler in the early 17th century. The law contributes to our understanding of planetary motion by providing a framework for predicting and explaining the paths that planets take as they orbit the sun. It also helped to disprove the previous belief that planets moved in perfect circles, leading to advancements in our understanding of celestial mechanics.
Why is the earth's orbit an ellipse?
Due to gravitational forces by other planets in universe,earth changes its circular orbit into ellipse.it has enough tangential velocity to leave the orbit and go straight,but sun attracts it and vice versa.
What is Kelpers law of planetary motion?
The path of the planets about the sun is elliptical in shape, with the center of the sun being located at one focus. (The Law of Ellipses)An imaginary line drawn from the center of the sun to the center of the planet will sweep out equal areas in equal intervals of time. (The Law of Equal Areas)The ratio of the squares of the periods of any two planets is equal to the ratio of the cubes of their average distances from the sun. (The Law of Harmonies)
Which instrument do you use to see stars and planets?
A spectrometer is used to determine the composition of stars, and how fast they are going relative to Earth.
An example of rotation?

What Was Nicolaus Copernicus Johannes jepler And William Harvey associated With?
Nicolaus Copernicus is best known for formulating the heliocentric model of the universe, which proposed that the Earth and other planets revolve around the Sun. Johannes Kepler, a key figure in the scientific revolution, is famous for his laws of planetary motion, which described the elliptical orbits of planets around the Sun. William Harvey is renowned for his discovery of the circulation of blood in the human body, which laid the groundwork for modern physiology and medicine. Together, these figures significantly advanced the understanding of astronomy and human biology.
Who is 'Kepler'?
Johannes Kepler (IPA: [ˈkʰɛplɐ]) (December 27, 1571 - November 15, 1630) was a German mathematician, astronomer and astrologer, and key figure in the 17th century scientific revolution.
Who is johanes Kepler?
Johannes Kepler (IPA: [ˈkʰɛplɐ]) (December 27, 1571 - November 15, 1630) was a German mathematician, astronomer and astrologer, and key figure in the 17th century scientific revolution.
Did Kepler support geocentric or heliocentric?
Kepler spent his entire adult life trying to figure out what kind of arrangement would be the simplest and most accurate explanation for the motions we actually see in the sky. He tried several of them, and he eventually determined that the best fit was obtained if the planets, including the earth, all moved in elliptical orbits around the sun. That's heliocentric.
Why was Johannes Kepler important?
He published accurate data on the positions of stars and planets which immensely helped navigators. He made various contributions to mathematics, including faster methods of calculation. He also improved optics. However, his main contribution with the greatest impact was Kepler's Laws of Planetary Motion. These laws provided the groundwork for many great scientific discoveries, including Sir Isaac's Newton's work on universal gravitation.
What are the three laws of Johannes Kepler all about?
Kepler's three "laws" of planetary motion constitute Kepler's explanation of the motions of the inner six planets of the solar system. He formulated them from years of sweating over the notebooks kept by another individual who spent his life watching the planets and keeping records of their motions. (Tycho Brahe). After Kepler's death, Isaac Newton developed his theory of gravity. Anybody who has enough geometry and calculus to give Gravity a good massage can show mathematically that IF gravity works the way Newton suggested it does, then the planets MUST move in the ways described by Kepler's Laws ... a nice confirmation of the work of both Newton and Kepler. These laws not only do a good job of describing how the planets move, but when we use Kepler's and Newton's formulas to figure out how to aim artificial satellites, Apollo capsules, and interplanetary probes to the outer solar system, those things always go where we want them to go ... more nice confirmation of the same theories. Oh yes. That's right. Both of them are "just theories".

Are the planetary orbits the same as the figure we have drawn?
yes it is 99.99% the same as we have estimated the orbits of the planets using newton's and Kepler's law and they cant be wrong
How did Kepler figure out that planets orbit is elliptical?
Kepler, the person who first wrote about elliptical orbits, had a Trinitarian view of the solar system in which it made perfect sense theologically to have the Sun at the centre of the universe. Copernicus also believed in a Sun-centred system.
Who confirmed copernicus' heliocentric theory?
Aristarchus of Samos
What was Kepter's theory of the solar system?
Tycho Brahe made very accurate observations of the solar system. Brahe's assistant, Johannes Kepler, used the observations to figure out the shape of the planets orbits. When he used circular orbits, his calculations did not fit the observations. But after years of detailed calculations, he found that the orbit of each planet is called an ellipse. An ellipse is an oval shape.
Are all orbits the same shape?
No, not all orbits are the same shape. Orbits can be elliptical, circular, parabolic, or hyperbolic, depending on the speed and trajectory of the object in space. The shape of an orbit is determined by the balance between the object's velocity and the gravitational pull of the body it is orbiting.
