Which list provides an accurate order for changing models of our solar system starting with the oldest and ending with the most recent changes
1. Geocentric Model: The oldest model of our solar system, proposed by ancient Greek astronomers, that placed the Earth at the center and considered other celestial bodies to orbit around it.
2. Heliocentric Model: Proposed by Nicolaus Copernicus in the 16th century, this model placed the Sun at the center of the solar system, with the planets revolving around it.
3. Kepler's Laws of Planetary Motion: Formulated by Johannes Kepler in the early 17th century, these laws describe the elliptical paths and equal area sweeping law of planetary motion.
4. Newton's Law of Universal Gravitation: Introduced by Sir Isaac Newton in the late 17th century, this law explained how objects in the solar system, including planets, moons, and comets, are held in their orbits by gravitational forces.
5. Discovery of Uranus: In 1781, the discovery of Uranus, the first planet not known since ancient times, led to the expansion of the solar system's known boundaries.
6. Neptune's Discovery: In 1846, the discovery of Neptune further expanded the known boundaries of the solar system.
7. Pluto's Discovery and Reclassification: Pluto was discovered in 1930 but was reclassified as a dwarf planet in 2006, marking a significant change in our understanding of the solar system.
8. Exoplanet Discoveries: Starting from the 1990s, the discovery of numerous exoplanets (planets outside our solar system) revolutionized our understanding of planetary systems and their formation.
Please note that this list focuses on major changes in our understanding of the solar system, and it is not an exhaustive account of all scientific developments.
