What 3 tools did nicolaus Copernicus use?
Basically, Copernicus used math to figure things out. To draw a figure for himself or for publication, he might use a compass or a straightedge, but what motivated his change from a geocentric to a heliocentric system---i.e., from an Earth-centered to a Sun-centered system---was a combination of aesthetics and mathematics. The reason people took him seriously is because of the latter: he provided a mathematical basis for saying that the Sun, and not Earth, lay at the center of our planetary system.
How did scientists views on the planetary paths change over time?
When it was believed that the planets revolved around the Earth, the planetary paths were plotted and were erratic and did not comply with the laws of motion and gravity as we now understand them. That was overlooked by the believers in an Earth centered Solar System.When the Sun centered Solar System was theorized by Copernicus, the paths of the planets around the Sun became organized into relatively circular (or elliptical). Much simpler, and following the Laws of Motion as proposed by Newton.
Which scientist proposed the idea of sun-centered solar system instead of an earth-centered solar system?

Which scientist proposed the idea of a sun centered solar system in stead of an earth centered solar system?

Which is biggest a planetary nebula a planetary system or a galaxy?
A galaxy is the biggest among the three. Galaxies contain billions to trillions of stars, as well as other celestial objects like planets and planetary nebulae. A planetary system refers to a star with its orbiting planets, while a planetary nebula is a glowing shell of gas ejected by a dying star.
What is the name of our planetary system?
Our planetary system is called the Solar System, named after the Sun (Latin: Sol) around which all the planets, moons, asteroids, and other celestial bodies orbit.
