Mercury - Has been known for thousands of years. However, it is the most difficult of the "naked eye" planets to see.
Venus - Has been visible to everyone who has looked into the skies.
Earth - The first to scientifically identify Earth as a planet was probably Copernicus.
Mars - Has been visible to everyone who has looked into the skies.
Jupiter - Has been visible to everyone who has looked into the skies.
Saturn - Has been visible to everyone who has looked into the skies.
Uranus - William Herschel was the first to see and identify Uranus as a planet.
Neptune - Johann Galle and Heinrich d'Arrest, based on calculations by Urbain Le Verrier (and John Couch Adams).
Ernest Rutherford devised the planetary model in 1911. This model was meant to discredit the plum pudding model of J.J. Thomson.
You don't really 'discover' a scientific model. You put one forward to explain observations.
The person's name was Niels Bohr.

its was Ernest Rutherford who proposed the planetary atomic model
The Bohr model of an atom was of planetary type.
The model atom Ernest Rutherford made is simply called the Rutherford Model. The experiment he conducted during his research is referred to as the Gold Foil Experiment. Rutherford is known as the father of nuclear physics.
Rutherford's experiment is called the Planetary Experiment because of Rutherford's concentration on most of the atom's mass into a very small core. The core would contain most of the atom's mass and in the same way the sun contains most of the solar systems mass.
a Bohr model is a diagram of an atom that describes the arrangement of the subatomic particles(electrons, neutrons, and protons) protons and neutrons are in the nucleus and the electrons in the electron shells.
Well one thing he invented was the atom bomb
The planetary model of an atom is simple. The nucleus is the planet and the electrons are the moons in the model.
Niels Bohr, he is the man who portrays the planetary model of an atom.

The Bohr model of the atom was a planetary model.
The Bohr model of the atom was a planetary model.
Johannes Kepler was the person who made the planetary model. He was a German astrologer, mathematician and astronomer. He was also a Mathematics teacher.
Bohr came up with the planetary model for the hydrogen atom - that began the physical explanation of quantum mechanics invented by Planck.
