The Ultimate Quiz on the Fundamentals of the Solar System and Planetary Models

Study Notes

There are four fundamental forces in the universe: gravity, electromagnetic, strong nuclear, and weak nuclear.
Observable components in the universe include planets, exoplanets, dwarf planets, satellites, stars, constellations, comets, galaxies, asteroids, and nebulas.
Geocentric models consider Earth as the center of the universe, while heliocentric models consider the Sun as the center.
Aristotelian and Ptolemaic models are geocentric, while Aristarchus, Copernican, and Galilean models are heliocentric.
The Copernican model states that the planets orbit the Sun in circular orbits.
The Galilean model supported the heliocentric theory with observations of the Moon, Venus, the Milky Way, the Sun, Jupiter, and Saturn.
All planets move around the Sun in elliptical orbits, with the Sun at one of the foci.
The aphelion is the point of the farthest orbit from the Sun, while the perihelion is the point of the closest orbit to the Sun.
Planets move faster when they are closer to the Sun (perihelion) and slower when they are farther away (aphelion).
The Solar System contains eight planets, including Earth, and the Sun holds almost all of the mass in the Solar System.
