The ​ ​ (a)   model places the Earth at the center of the universe, while the ​ ​ (b)   model places the Sun at the center. Additionally, ​ ​ (c)   used the phases of Venus as evidence for the latter model.

• geocentric
• heliocentric
• Galileo
• Kepler
• Copernicus
• Ptolemy

Which of the following observations supported the heliocentric model of the solar system?

• Retrograde motion of planets

• Phases of Venus

• Circular planetary orbits

• Moons orbiting Jupiter

• Lack of parallax in stars

Why is Venus hotter than Mercury, even though Mercury is closer to the Sun?

• Venus reflects more sunlight from its cloud layers

• Venus has a thicker atmosphere that traps infrared radiation

• Venus has a magnetic field that generates aurora

• Mercury absorbs more heat

Rank these objects in order of increasing orbital period (shortest to longest):

• Saturn

• Pluto
