Kepler discovered that the planets orbit the Sun in elliptical shapes, not in perfect circles as previously believed. This finding is summarized in Kepler's first law of planetary motion.
Johannes Kepler discovered that the path that planets follow around the sun is an elliptical shape. This is known as Kepler's First Law of Planetary Motion.
The first two planets in our solar system are Mercury and Venus. Mercury is the closest planet to the Sun, while Venus is the second planet from the Sun and is known for its thick atmosphere and extreme heat.
The asteroid Ceres was discovered in 1801; the planet Pluto was discovered in 1930. In 2006, the International Astronomical Union decided to formally define a "planet"; this had never been formally done before. The discoveries of other distant objects beyond Pluto caused the IAU to finally come up with a rule. According to the new rule, Pluto, Ceres, and Eris (a newly discovered "tenth planet") were all classified as "dwarf planets".
The same number as there are now, but they weren't all discovered by then. Mercury, Venus, Earth Mars, Jupiter, and Saturn have been known since ancient times. Uranus was first recorded in 1690 Neptune was discovered in 1846 Pluto was discovered in 1930, and later declassified as a planet. So, in 1780, we knew of 7 planets,
Earth, then Jupiter, Saturn, Venus, and Mars.
No. He discovered great moons, which, had they not been orbiting planets might have been considered planets themselves, but the first new planet since antiquity was Uranus, discovered by Sir William Herschel.
Two of them are the third of gas planets and the first discovered in modern times
I think this is called the Heliocentric Theory and was first discovered by Copernicus.

Some of the newly discovered planets beyond Pluto include Eris, Haumea, Makemake, and Gonggong. These are classified as dwarf planets due to their size and orbit characteristics. There have been no new planets discovered in our solar system beyond Pluto that are not classified as dwarf planets.
Ceres and Eris are not planets; they are classified as dwarf planets. Eris was discovered in our solar system recently and not by the Kepler mission. Ceres is not "new" either; it was discovered the first day of the 19th. Century. I didn't check the specific "Kepler-" codes, but that looks like planets discovered by the Kepler mission to be orbiting around other stars.
Mars is one of the five planets that can be seen without a telescope. It is unknown who first discovered Mars because it has been known since antiquity.
He never discovered any planets but he discovered that the earth wasnt the center of the universe
17th century astronomer Johannes Kepler discovered the elliptical shape of the planets' orbits around the Sun, which he described in his first law of planetary motion. Newton later explained this in his law of universal gravitation.
Mercury, Venus, Mars, Jupiter and Saturn were the first five planets to be discovered buy ancient civilisations. these five are also known as the `classical planets`.
