Nicolaus Copernicus!
Mars - because the surface is covered in iron oxide (Rust). This gives Mars it's "red" appearance.
Pluto is part of our solar system, so it is not located outside of it. The nearest solar system to ours is the Alpha Centauri system, which is about 4.37 light years away from us. Pluto is about 4.67 billion miles away from Earth at its farthest point.
He apologized and said he was wrong apex
it means that Copernicus ( the discoverer ) felt as if the sun is the center of the universe. ptolemy and Copernicus bumped heads for years because ptolemy belived that the earth was the center of the universe
He was charged with heresy, a serious crime in those days, for contradicting the church's belief that the Earth is at the centre of the Universe. The church said that if there was proof of this idea, they would have to have a rethink. But in court Galileo could produce no proof and he recanted. But later in the 17th century after Galileo's lifetime scientific discoveries led everyone to accept that the Sun is at the centre of the solar system (but not the Universe).
The Copernican Theory said that the Sun was the centre of the solar system, not the Earth. The only error he made was that the orbits were perfectly circular. Keplar corrected this by showing the orbits were ellipses.
I believe no scientist said exactly this. It is the (two) electrons in the same orbital that must have opposite spins. And the scientist who said that was Wolfgang Pauli in 1925. (Pauli exclusion principle)
This is an ongoing study, but it has been said that there has been sightings of another planet in the solar system.

Yes. A solar system, by definition, is a system of objects orbiting a central star. The central star of said system is called a sun.(Note that a common misconception is that the sun of our solar system, Sol, is named "Sun.")
Mikołaj Kopernik
The first scientist to say the earth is not the centre of the whole universe was Nicolaus Copernicus early in the sixteenth century.
If you are a student your should ask your lecturer or teacher. this is because in older textbooks, pluto is one of the nine planets of the solar system. however latest discovery said that pluto is a moon of the solar system and not a planet.
"Sol" is a really old name for our sun. Therefore, our sun and all the planets, asteroids, comets, and planetoids are said to be in the SOL-ar system. The Solar system that we live in is the only one with that name.
Well the sun is in the center of our solar system. People have said that in about 5 billion years the sun will dime and that it will expand and eat Mercury and Venus and that Earth will have to much heat.
