Contribution of Copernicus?
Copernicus provided a groundbreaking heliocentric model of the universe, shifting from the Earth-centric view to the Sun at the center of the solar system. His work laid the foundation for modern astronomy and greatly influenced scientific thought during the Scientific Revolution. Copernicus's contributions challenged traditional beliefs and paved the way for a more accurate understanding of the cosmos.
How many planetoids and planets in solar system?
there are nine planets in the solar system if we add Pluto.
The observed retrograde motion of planets led ptolemy to add blank to Aristotles system?
The observed retrograde motion of planets led Ptolemy to add epicycles to Aristotle's system. Epicycles were small circles that planets moved in on their larger circular orbits around Earth in order to explain the appearances of retrograde motion.
Is there only 8 planets in the solar system?
No, there are actually 8 recognized planets in our solar system—Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. The former ninth planet, Pluto, was reclassified as a dwarf planet in 2006 by the International Astronomical Union.
Why does it take so long to get to other planets?
The distances between planets in our solar system are vast, and the technology we currently have can only travel so fast. Additionally, we need to carefully plan missions to ensure the safety of astronauts and the success of the mission, which can add to the time it takes to travel to other planets.
