  • Q2
    You observe 4 stars from two different locations. Which star will have the greatest parallax?

  • Q3
    How did Aristotle explain the way that objects in the universe move?
    Objects move in circles on 1 sphere, with Earth at center
    Move in circles on small spheres in large ones Earth center.
    Objects have elliptical orbits, with Earth at the center
    Objects have elliptical orbits with the sun at the center
  • Q4
    Who explained the parallax problem saying there was no parallax because stars were far away?
  • Q5
    The drawing shows Galileo's observations of Jupiter. What did Galileo’s observations show?
    Question Image
    All celestial bodies orbited the sun.
    Planets other than Earth had bodies moving around them.
    Planets had elliptical orbits.
    All celestial bodies orbited Earth.
  • Q6
    According to Johannes Kepler's laws, how do planets move in the solar system?
    circular orbits around Earth
    elliptical orbits around the sun
    circular orbits around the sun
    elliptical orbits around Earth
  • Q7
    Which statement supports a geocentric model of the no parallax problem?
    Earth is not moving, so no parallax exists
    The stars are too far away for a visible parallax
    The stars are too close for a visible parallax
    Observation points differ, so there is no visible parallax
  • Q8
    The diagram shows several objects in space. Which best identifies what the diagram shows?
    Question Image
    heliocentric solar system
    geocentric star system
    location of comets

  • Q11
    The diagram shows which theory about Earth and its neighbors in space?
    Question Image
    Aristotle’s theory
    heliocentric theory
    Ptolemy’s theory
    geocentric theory
  • Q12
    How does Ptolemy’s model of the universe compare with Aristotle’s model?
    Both models show celestial objects have elliptical paths
    Both models are based on parallax.
    Both models are heliocentric.
    Both models show celestial objects have circular paths.
  • Q13
