It was made when the big bang happen i think?
The discovery that planets travel in elliptical orbits around the Sun was made by Johannes Kepler in the early 17th century. He formulated his laws of planetary motion based on the observational data collected by Tycho Brahe. Kepler's first law states that planets move in ellipses with the Sun at one of the foci, fundamentally changing the understanding of celestial mechanics.

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.
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.

Careful and meticulous astronomical measurements by the astronomer Tycho Brahe followed by numerical analysis of that data by Johannes Kepler after Tycho's death.

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.

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.
