What observations made by Galileo supported Copernicus's theory about the solar system?
Galileo discovered moons orbiting Neptune, showing that not all things travel around Earth. He also observed that Pluto goes through phases, much like our moon's phases, suggesting it orbits the sun.
Galileo discovered moons orbiting Jupiter, showing that not all things travel around Earth. He also observed that Venus goes through phases, much like our moon's phases, suggesting it orbits the sun.
Galileo discovered moons orbiting Mars, showing that not all things travel around Earth. He also observed that Saturn goes through phases, much like our moon's phases, suggesting it orbits the sun.
Galileo discovered moons orbiting Earth, showing that not all things travel around Venus. He also observed that Neptune goes through phases, much like our moon's phases, suggesting it orbits the sun.
Which patterns in space are predictable?
The movements of planets and moons are unpredictable. The patterns of stars are predictable.
The movements of asteroids and moons are predictable. The patterns of stars are unpredictable.
The movements of UFO's and moons are predictable. The patterns of stars are predictable.
The movements of planets and moons are predictable. The patterns of stars are predictable.
Some early observers thought Earth was the center of the universe, based on observations of the movement of stars, moon, and planets. They made Earth-Centered models. Later, scientists observed … what?
That the planets all revolve around the sun, not Earth. So scientists made sun-centered, or geocentric models.
That the planets all revolve around the Earth, not the sun. So scientists made sun-centered, or heliocentric models.
That the planets all revolve around the stars, not Earth. So scientists made sun-centered, or geocentric models.

Aristarchus
Copernicus
Kepler
Brahe
He was an ancient Greek scientist who first developed a heliocentric model.
Aristarchus
Copernicus
Kepler
Brahe
His calculations proved that the shape of a planet's orbit is an ellipse, not a circle.
Aristarchus
Copernicus
Kepler
Brahe
He said Earth's rotation and revolution around the sun explained stars moving.
Aristarchus
Copernicus
Kepler
Brahe
