Answers
1
Which was not observed by Galileo?
moons of Jupiter
Pluto
phases of Venus
craters on the moon
2
Which best describes Tycho Brahe's "compromise model" of planetary motion?
planets orbit the Earth
Earth spins while the others are stationary
planets orbit the sun but the sun orbits Earth
planets orbit the sun
3
What evidence suggested that the geocentric model was incorrect?
the orbits of planets being ellipses not circles
apparent daily motion
objects revolving around something besides earth
epicycles
4
Who is the father of the geocentric theory?
Copernicus
Aristotle
Ptolemy
Galileo
5
Why can we only see certain constellations in certain seasons?
It is darker in winter, so we can see more constellations.
Earth moves around the sun while the stars stay on one spot.
We can't see them when it is daylight.
Earth is tilted away from them at times.
6
Are models of the solar system drawn to scale regarding planet size and distances between them?
No. The distances are too great to draw to scale.
No. In models, only the outer planets are drawn to scale.
Yes. The inner planets are always drawn to scale in models.
Yes. Those models are more accurate.
7
What is a constellation?
a group of stars near Earth
a group of stars that form a picture
a group of stars that tell a story
a group of planets that move in the night sky
8

comets
dwarf planets
planets
moons
9
When looking through a telescope, you are seeing objects as they looked in the past.
False
True
10
Kepler used the data of what astronomer to develop his laws of planetary motion?
Copernicus
Tycho Brahe
Ptolemy
Galileo
11
Galileo used his telescope to discover which of the following:
sunspots
that planets' orbits are ellipses
Venus had phases like Earth's moon
Earth is not the only planet with an orbiting moon
12
_ apparent shift in postion of an object while viewed from different points helped to explain _
Retrograde motion, geocentrism
Parallax, retrograde motion
Parallax, geocentrism
Parallax, heliocentrism
13
Kepler's laws of planetary motion state all of the following EXCEPT:
orbits are ellipses
planetary motion is uniform
a planet's speed varies with its distance from the sun
the closer the planet is to the sun the faster it orbits
14
How many planets have astronomers identified in our solar system?
9
8
5
12
15
The idea of an Earth-centered universe is called:
the geocentric theory
retrograde motion
transit
the heliocentic theory
16
Greek astronomers called the planets "asters planetai, "meaning "wandering stars."
False
True
17
Ptolemy used "epicycles" to explain ____________.
planetary transit of the sun
phases of the moon
the planets orbits
retrograde motion
18
Why do stars appear to move in the sky?
The stars are rotating.
The Earth revolves.
The Earth rotates.
The stars orbit around Earth.
19
Who is the father of the heliocentric theory?
Kepler
Copernicus
Pythagoras
Galileo
20
Which astronomers proposed the heliocentric model?
Kepler and Brahe
Plato and Aristolte
Kepler and Galileo
Copernicus and Galileo
21
Kepler refined the heliocentric model stating the planets moved in elliptical orbits meaning:
The orbits were oval.
The orbits were perfect circles.
The orbits were epicycles.
The orbits were straight lines.
