Question

which contributions did galileo make to the model of the solar system? select two options.
□ a mathematical model for the orbits of the planets
□ scientifically accurate data on planetary orbits
□ data that showed that planets reflected sunlight similar to earths moon
□ the idea that stars are other suns that do not move
□ observations of the moons of jupiter rotating around the gas giant

Explanation:

• Kepler developed the mathematical orbital model for planets.
• Tycho Brahe gathered accurate planetary orbit data.
• Galileo observed Venus' phases, proving planets reflect sunlight like the Moon.
• Galileo discovered Jupiter's moons orbiting it, challenging geocentrism.
• The idea of stars as stationary suns was not Galileo's key solar system contribution.

Answer:

• data that showed that planets reflected sunlight similar to Earth’s moon
• observations of the moons of Jupiter rotating around the gas giant
