12
What is Kepler's First Law of planetary motion?
Planet's orbital period is proportional to distance from sun
A planet sweeps equal areas around its orbit in equal time.
Gravity increases as mass increases or distance decreases.
Orbits are elliptical.

Ptolemy
Galilei
Copernicus
Aristarchus
18
What is Kepler's Second Law of planetary motion?
Gravity increases as mass increases or distance decreases
planet's orbit is elliptical
A planet sweeps out equal orbital areas in equal time.
planet's orbital period is proportional to distance from sun
19

26
German astronomer formulated 3 laws of planetary motion:
Ptolemy
Copernicus
Aristotle
Kepler
27
Why isn't Pluto considered a planet?
It became a comet and went off its orbital path.
It stopped rotating and orbiting.
Objects were found in its orbital path
A collision made it smaller.
28
What is the Oort cloud?
area between the sun and Mercury
shell of icy objects surrounding our solar system
area between asteroid belt and Kuiper belt
objects in the main-asteroid belt
29
