Name Kepler’s First Law of Planetary Motion
A 100
Law of Ellipses
A 100
What is the eccentricity of an ellipse that
has the following dimensions?
Distance between foci = 5 cm
Length of Major axis = 26cm
A 200
E = d/L
E = 5cm/26cm = .192
A 200
Name the term used to
describe Earth when it is
closest to the sun.
A 300
Perihelion
A 300
Name and describe Kepler’s
Second Law of Planetary Motion
A 400
Law of Equal Areas
- Equal areas are swept in equal
amounts of time when an object
orbits the sun
A 400
Explain how the kinetic and
potential energy of a celestial
object varies as it revolves round
the sun.
Use the terms: perihelion,
aphelion, gravity, and velocity in
your explanation
A 500
As a celestial object (comet, planet,
asteroid) approaches perihelion the effect
of gravity rises, causing velocity to
increase, therefore transforming the
object’s potential energy to kinetic.
Perihelion: Kinetic energy highest,
potential lowest
Aphelion: Potential highest, Kinetic lowest
A 500
Name one piece of evidence
that supports Earth’s
revolution.
B 100
Seasons, Parallax,
Constellations, Doppler
Effect, Apparent
Diameter
B 100
Answer the following in
the form of a question!
B 200
A group of stars that
form a pattern in the
night sky that are used to
locate celestial objects
B 200
Explain how the
changing diameter of the
sun supports the theory
that Earth revolves.
B 300
The sun’s actual diameter does
not change in a cyclic manner.
When the sun appears larger we
are closer (perihelion) and when
the sun appears smaller Earth is
farther (aphelion). This change
in apparent diameter would not
occur if we were not moving!
B 300
Please explain what
would happen to Earth if
it did not revolve.
B 400
-No change of season
- One perpetual season all year
long!
B 400
Explain how an
astronomer can
determine the distance a
star is away from Earth
by using parallax.
B 500
The larger the
parallax shift, the
closer a star is away
from Earth.
B 500
What causes the seasons
to change?
C 100
-Earth tilted axis (23.5o)
- Earth’s revolution
C 100
What latitude is the sun
directly overhead on
st
June 21 ?
C 200
Tropic of Cancer
C 200
On what date will there
be 24 hours of darkness
at the South Pole?

C 400
How many hours of daylight
will Oslo, Norway have on
March 21st?
C 400
12! Every location on
Earth experiences 12
hours of daylight and
darkness on the
Equinox!
C 400
Four celestial spheres, A, B, C, and D, are depicted above.
Each sphere represents a different location. Which sphere
depicts the apparent motion of the sun on June 21st in New
Zealand? Please explain.
C 500
Location D
The noontime sun is located in
the northern sky. In the southern
hemisphere an observer would
have to look north to see the
noontime sun.
C 500
How does the length of
the sun’s arc across the
sky relate to the length
of day?
D 100
Longer the arc, the
longer the day!
D 100
What direction would a
person have to face to the
see the noontime sun in
NYS?
D 200
South!
D 200
Answer the following in
the form of a question!
D 300
Stars that complete one
full circle about Polaris
in 24 hours.
D 300
What does the term
‘planet’ actually mean?
D 400
Wanderer
D 400
How did the ancient
Babylonian civilization
properly sequence the
planets?
D 500

D 500
What shape do celestial
objects make across the
sky?
E 100
Arcs!
E 100
At what rate do stars
move across the celestial
sphere?
E 200
15 degrees per hr
E 200
Why do planets
sometimes appear to
move backwards in
relation to the
background stars?
E 300
Retrograde motion is caused by
planets passing one another. For
example, as Earth catches up and
passes by Mars, Mars appears to
move backwards.
E 300
Betelguese rises in the east at
6:00pm and reaches its highest point
in the sky at 1:00am. How many
degrees has the star travelled?
E 400
7 hrs x 15o/hr = 105o
E 400
The celestial hemisphere above represents a
particular location on Earth. Where is this person
located?
E 500
The North Pole! 90o N
Polaris is directly overhead!
E 500
Name the hypothesis that
explains the origin of the moon.
F 100
The Giant Impact Hypothesis
F 100
How many days does it take the
moon to complete one full
revolution around Earth?
F 200
Sidereal Month = 27.3 Days
F 200
Name the phase!
F 300
F 300
How many days does it take the
moon to go from lunar phase #1
to lunar phase #2?
F 400
#1 Full moon
#2 Waning Gibbous
3.6 Days!
F 400
Why does it take the moon
longer to complete a synodic
month than a sidereal month?
F 500
Throughout the year, the Earth is
revolving around the sun. After
the completion of one full
revolution around the Earth
(sidereal month), the moon needs
to revolve slightly further to
realign with the Earth and sun.
This time lag results in a
difference of 2.2 days.
