Final answer:
Copernicus, Galileo, and Kepler contributed to the acceptance of the heliocentric model by developing theories and making observations. The solar system consists of the Sun, planets, dwarf planets, asteroids, comets, and other celestial bodies.
Step-by-step explanation:
Nicolaus Copernicus, Galileo Galilei, and Johannes Kepler made significant contributions to the acceptance of the heliocentric model of the solar system. Copernicus developed the heliocentric model, which proposed that the Sun is at the center of the solar system and that the planets orbit around it.
Galileo's discoveries using his telescope provided observational evidence that supported the heliocentric model. He observed the phases of Venus, the moons of Jupiter, and the features of the Moon, all of which provided proof that the Earth is not at the center of the universe.
Kepler, building upon Copernicus's work, formulated three laws of planetary motion. These laws described the elliptical paths of planets around the Sun and provided further evidence for the heliocentric model.
The objects that make up the solar system include the Sun, planets (such as Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune), dwarf planets (such as Pluto), asteroids, comets, and various other celestial bodies.
