ASTRO 7N Unit 2 Part 1: Jupiter's Moons
& Kepler's Laws
Besides, the discovery that moons orbit Jupiter, what other discovery made by Galileo
Galilei, with an early telescope, proved that the Earth is not at the center of the Universe? -
correct answer-the phases of Venus

What was Kepler's First Law? - correct answer-Planets revolve around the sun in elliptical
orbits with the Sun at one focus of the ellipse.

We saw that Kepler's 3rd law states that P^2/a^3 = constant. What does P represent in this
equation? - correct answer-orbital period, in this case how long it takes for a satellite to orbit
Jupiter

What best describes the orbit of earth around the Sun? - correct answer-An ellipse that is
close to being circular.

Of the four Galilean moons, which is closest to Jupiter? - correct answer-Io

Which of the following does Kepler's Second Law support? - correct answer-When a planet
is closer to the Sun, its speed is greater than when it is farther away.

Which moon of Jupiter is believed to have a liquid ocean beneath a layer of ice? - correct
answer-Europa

How did Kepler himself originally state his second law? - correct answer-A line joining a
planet and the Sun sweeps out equal areas in equal intervals of time.

Which moon of Jupiter is the largest? - correct answer-Ganymede

What was Kepler's Third Law? - correct answer-The square of the time period for an orbit of
a planet is proportional to its average distance from the Sun (in other words P^2 is
proportional to a^3)

Saturn is about 10 times as far from the Sun as Earth is (a = 10 AU, roughly). About how
many times does the Earth orbit the Sun in the time it takes Saturn to orbit just once? -
correct answer-About 30
