Mid Term Exam Review

In 1610, Galileo first observed what looked like three small stars near Jupiter. As Galileo continued to make observations, he saw that these "stars" seemed to follow Jupiter and change their positions around it. This led Galileo to conclude that Jupiter was orbited by moons that were like Earth's moon. Which of these BEST describes the impact of this research?

• proving that Earth and Jupiter are both orbiting the Sun

• showing that planets besides Earth and Jupiter must have moons

• proving that Jupiter was the largest planet in the solar system

• showing that Earth was not the center of motion in the universe
