2) Galileo
3) Copernicus
4) Tycho Brahe
5) Ptolemy

Answer 1

Nicolaus Copernicus authored 'De Revolutionibus Orbium Coelestium', which introduced the heliocentric model of the universe and was published in 1543.

Thus option 3) Copernicus. is correct answer.

Step-by-step explanation:

The revolutionary book that placed the Sun at the center of the planetary system is De Revolutionibus Orbium Coelestium (On the Revolution of Celestial Orbs), authored by Nicolaus Copernicus. Published in 1543, the year of his death, it introduced the heliocentric model of the universe, challenging the long-standing geocentric model previously endorsed by Ptolemy.

While not widely accepted immediately, Copernicus's work later had a profound influence on the scientific understanding of our solar system and marked the beginning of modern astronomy.

Thus option 3) Copernicus. is correct answer.
