Question

question 1 - 14
how does the modern model of the solar system compare to previous historical models?
scientists included asteroids
scientists removed the sun from the model.
scientists placed the earth at the center again.
scientists proposed that planets orbit in elliptical paths

Explanation:

In previous models like the Ptolemaic (Earth - centered with circular orbits) and early Copernican (Sun - centered with circular orbits), orbits were thought to be circular. Kepler's laws (a key part of the modern model) proposed that planets orbit in elliptical paths. Asteroids were not a main differentiating factor compared to the fundamental orbital shape change. The Sun is at the center in the modern model (not removed). The Earth is not at the center in the modern model.

Answer:

Scientists proposed that planets orbit in elliptical paths.
