Which list provides an accurate order for changing models of our solar system, starting with the oldest and ending with the most recent changes?

Answer 1

The historical models of our solar system, from oldest to most recent, would be as follows:

1. Geocentric Model (Ancient Greece) - This model, primarily associated with Claudius Ptolemy, placed the Earth at the center of the universe, with all other celestial bodies orbiting around it.

2. Heliocentric Model (16th Century) - Proposed by Nicolaus Copernicus, this model suggested that the Sun is at the center of our solar system, with the Earth and other planets orbiting around it.

3. Kepler's Laws of Planetary Motion (early 17th Century) - Johannes Kepler developed three laws that described the motion of planets around the Sun, introducing the idea of elliptical orbits rather than circular ones.

4. Newton's Law of Universal Gravitation (1687) - Isaac Newton's work further explained planetary motion through the concept of gravity, solidifying the heliocentric model and providing the mathematical framework for planetary orbits.

5. Modern Solar System Model (20th Century to Present) - This includes discoveries related to the composition of planets, the recognition of the role of gravity at a larger scale, the understanding of the solar system's formation, and the existence of exoplanets.

In summary, the accurate order is:

1. Geocentric Model
2. Heliocentric Model
3. Kepler's Laws of Planetary Motion
4. Newton's Law of Universal Gravitation
5. Modern Solar System Model

Answer 2

Elliptical orbits, heliocentric, geocentric

Elliptical orbits, geocentric, heliocentric

Heliocentric, geocentric, elliptical orbits

Geocentric, heliocentric, elliptical orbits

Answer 3

The correct order for changing models of our solar system, starting from the oldest to the most recent, is:

Geocentric, Heliocentric, Elliptical Orbits

So, the accurate choice would be:

Geocentric, heliocentric, elliptical orbits.

Explanation:

1. Geocentric Model - The idea that the Earth is at the center of the universe (ancient model).
2. Heliocentric Model - The concept that the Sun is at the center of the solar system (introduced by Copernicus).
3. Elliptical Orbits - The realization by Kepler that the planets move in elliptical orbits around the Sun, which refined and further developed the heliocentric model.

This sequence progresses from the earliest understanding (geocentric) to the modern understanding of planetary motion (heliocentric and elliptical orbits).
