This model says that the earth is at the center of the universe and everything else revolves around it.

• Zodiacal Model

• Geocentric model

• Aristarchus Model

• Heliocentric Model

Which of the following ideas of Aristotle's is actually true?

• The Earth is the center of the universe.

• All the planets and stars are all perfect spheres.

• The paths the planets follow in the sky are perfect circles.

• The Moon shines by reflecting the Sun's light.

Aristarchus' model of the universe was rejected until the 1500's because no one could show this was happening:

• Parallax

• Retrograde motion

• Epicycles

• Perihelion

In order to explain retrograde motion, Ptolemy added these to the orbits of planets.

• Ellipses

• Epicycles

• Cycloids

• Parabolas

Parallax is seen when...

• A nearby object appears to move against a distant background.

• Two stars are appear to move parallel to each other.

• A planet starts moving backwards in its orbit.

• A comet's tail gets larger the closer it is.

The first scientist to propose a heliocentric model for the universe after Aristarchus was:

• Leonardo da Vinci

• Johannes Kepler

• Sir Francis Bacon

• Nicholas Copernicus

Kepler was only able to formulate his laws of planetary motion because of the observations this scientist made.

• Tycho Brahe

• Galileo Galilei

• Linus Pauling

• Nicholas Copernicus

Which of the following is not one of Kepler's Laws of Planetary Motion?

• A planet moves faster when it is closer to the Sun.

• The force the Sun exerts on a planet is based on the square of the distance between them.

• The further a planet is from the Sun, the longer it takes for one orbit.
