Answer 1

The correct order for changing models of our solar system, starting with the oldest and ending with the most recent, is:

geocentric, heliocentric, elliptical orbits.

1. Geocentric model: This was the earliest model where Earth was considered the center of the universe (Ptolemaic model).
2. Heliocentric model: This model proposed by Copernicus placed the Sun at the center of the solar system.
3. Elliptical orbits: This concept, formulated by Johannes Kepler, refined the heliocentric model by describing the orbits of planets as elliptical rather than circular.

So the correct sequence is: geocentric, heliocentric, elliptical orbits.
