Any discoveries made by Hypatia did not survive.
He simply discovered many things that makes technology where we are! -m In astronomy he used measurements made by Tycho Brahe to do many complicated calculations to discover the shape of the planets' orbits. The results were published as the three laws of planetary motion in 1618. They were found to give good results when used to predict the future positions of the planets. For this work Kepler is recognised as one of the founders of modern astronomy. ________________________________ Kepler worked with Tycho Brahe for several years. Brahe had no great skill in science or mathematics, but was a METICULOUS and precise observer. Based largely on Brahe's observations, Kepler was able to determine that the planet Mars - and by extension, all the other planets - traveled in elliptical paths under the influence of a force that was inversely proportional to the square of the distance between the Sun and the planet. This paved the way for Newton's development of calculus and the math that describes gravity.
The shape made inside a circle by an arc and two radii is a sector.
Silver has no intrinsic shape. So it can be made into near enough any shape!

Johannes Kepler made the discovery of the planets' elliptical orbits in the early 17th century. He used observational data gathered by Tycho Brahe to formulate his three laws of planetary motion, which defined the precise shape and behavior of the orbits. This groundbreaking work laid the foundation for our modern understanding of planetary motion.

planets of course, or asteroids. both are rock
Johannes Kepler discovered that planets move in elliptical orbits by analyzing detailed astronomical data compiled by Tycho Brahe. Kepler's observations and calculations led to his discovery of the Three Laws of Planetary Motion, which revolutionized our understanding of celestial mechanics.
The planets' own gravity has made them spherical. Also there are other effects such as their ability to retain an atmosphere, etc. The Sun's gravitycauses the orbits of the planets.
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.
Johannes Kepler in the early 17th century. He developed his three laws of planetary motion, with the first law stating that planets move in elliptical orbits with the Sun at one focus.
Johannes Kepler, a German astronomer, discovered that planets move around the sun in elliptical orbits in the early 17th century. This was based on observations made by Tycho Brahe. Kepler's laws of planetary motion revolutionized our understanding of the solar system.
The inner planets are smaller, denser, and rocky, while the outer planets are larger, less dense, and composed mostly of gas. Inner planets are closer to the sun and have shorter orbits, while outer planets are farther away and have longer orbits. Additionally, inner planets have few or no moons, while outer planets have numerous moons.
The discovery of additional planets was made possible by advancements in telescope technology, particularly the development of large ground-based telescopes and space telescopes like the Hubble Space Telescope. These telescopes allowed astronomers to observe distant planets more effectively and detect previously unknown planets orbiting other stars.
