Only two of the planets (if we exclude Pluto) have official discoverers because the others have always been visible to the unaided eye. The two that were discovered are Uranus (in 1781) and Neptune (in 1846). Former planet Pluto was discovered in 1930.
As a preliminary, there are only 8. Pluto is technically no longer a planet.
It's not known when Mercury, Venus, mars Jupiter and Saturn where discovered, as they where know about throughout all written history in lots of cultures. So it's not recorded. Uranus 1781, Neptune 1846 Pluto, not considered a plant anymore 1930
The five (Mercury, Venus, Mars, Jupiter and Saturn) visible planets have been known since humans first looked up into the night sky. The Earth was also known.
Mercury, Venus, Mars, Jupiter and Saturn have been known, or at least seen since man first looked up into the sky. Uranus was also visible with the naked eye, but was probably not recognised as a planet by our early observers.
With the invention of telescopes, other planets were later discovered.
Neptune was discovered on September 23, 1846, but was mathematically predicted much earlier.
Pluto, although now a dwarf planet was discovered in 1930.
the following planets were known since ancient times and we cannot estimate the year
Uranus-Uranus had been observed on many times before its discovery as a planet, but it was generally mistaken for a star. The earliest recorded sighting as a planet was in 1690 when John Flamsteed observed it
Neptune- Neptune was first observed on December 28, 1612, and again on January 27, 1613 by Galileo
PlutoPluto was Discovered by Clyde W. Tombaugh in February 18, 1930
Here is a list of all planets including dwarf planets with their years of discovery:
Neptune was discovered in 1864 Uranus was discovered in 1781 sorry that is all i know :>
If your talking about earth, it was never discovered.
Mercury, Venus Earth, Mars, Jupiter and Saturn have all been known of since ancient times. Uranus was discovered in 1781 and Neptune was discovered in 1846.
the first planet to be discovered was earth.
The first two planets discovered were Earth and Mars.Another Answer:The first two planets, with respect to the Sun, are Mercury and Venus.
I would imagine the first humans who walked the Earth. The planets Mercury, Venus, Mars, Jupiter and Saturn can all be seen with an unaided eye. They were, then, called Wandering Stars as they "seemed" to wander the skies unlike the "fixed" stars.
Most exoplanets so far discovered resemble Jupiter. However, Earth sized planets have also been discovered and more will be discovered.
The gas giant planets Uranus and Neptune.
Johannes Kepler

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.
No planets have been discovered using a microscope.
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.
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.
well the moon... but that's not really a planet so logically we found the closest planets first.
He never discovered any planets but he discovered that the earth wasnt the center of the universe
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`.
