Johannes Kepler stated that the planets moved in elliptical orbits around the sun. This was one of his three laws of planetary motion, which he published in the early 17th century. These laws revolutionized our understanding of the solar system and replaced the previously held idea of circular orbits.
Johannes Kepler proposed the idea that planets revolve around the sun in elliptical orbits in his laws of planetary motion. This idea challenged the prevailing belief at the time that the Earth was the center of the universe.
Johannes Kepler was the first to state that planets move in elliptical orbits.
Terrestrial planets move faster in their orbits because they are closer to the Sun. Isaac Newton, who discovered the effects of gravity, stated that gravity gets stronger the closer you get to a large, massive body (like the Sun) - and this makes the planets orbit faster than the outer planets, where the force of the Sun's gravity is less. Their orbits are also smaller, so it takes less time for them to go around the Sun.
In ancient Greece, the astronomer Ptolemy proposed the geocentric model, which stated that the planets revolved around the Earth. This model was widely accepted for centuries until it was ultimately replaced by Nicolaus Copernicus' heliocentric model, which placed the Sun at the center of the solar system.

Neils Bohr, in 1913. He depicted an atom as a small area of positively charged particles in the middle and electrons circulating this in orbits around the outside.

Johannes Kepler was the first to state that planets move in elliptical orbits.
He is a danish astronomer who stated that all the planets revolve around the sun in elliptical orbits and that the sun is not in the exact center of the orbit.
Johannes Kepler stated that the planets revolve around the sun in an ellipse.
he stated that planets went around the sun
The person who first stated this was Johannes Kepler.
Terrestrial planets move faster in their orbits because they are closer to the Sun. Isaac Newton, who discovered the effects of gravity, stated that gravity gets stronger the closer you get to a large, massive body (like the Sun) - and this makes the planets orbit faster than the outer planets, where the force of the Sun's gravity is less.
