Without the image to reference, I can provide some information about the models of these astronomers:

  • Ptolemy: Proposed a geocentric model of the universe where the Earth is at the center, and all planets and the Sun orbit around it.
  • Copernicus: Developed a heliocentric model, placing the Sun at the center of the solar system, with Earth and the other planets orbiting around it.
  • Kepler: Refined the heliocentric model with his laws of planetary motion, proposing that planets move in elliptical orbits rather than circular ones.
  • Newton: Introduced the laws of motion and universal gravitation, providing a theoretical framework that explained the forces behind celestial motions but did not propose a new model of the solar system.

If the model depicted in the picture shows the Earth in the center with planets moving in circular orbits, it would be Ptolemy's model. If it shows the Sun in the center, it would represent Copernicus's model. If it illustrates elliptical orbits, it would be associated with Kepler.

Please describe the model or provide more context, and I will help you identify which astronomer's model it is!
