Kepler's law states that all our planets move in an ellipse. One of the two foci points is
the North Star
the Sun
Betelgeuse
the Earth
5
How much sunlight is the north pole receiving at the date represented by the picture below?
0
9
24
12
6
As you decrease the distance between two foci points, the eccentricity
increases
remains the same
decreases
7
The different constellations observed from NYS during different seasons is because
The Earth is tilted on it's axis.
The stars move around Earth as shown by star trails.
The lengths of day and night are different.
Earth moves in it's orbit around the Sun.

uniform daylight hours
365.25 day year
seaons
24 hour day
20
Why does the sun's vertical rays hit different latitudes at each numbered location?
Due to the the Sun's rotation
Due to Earth's rotation
Due to Earth's tilt
Due to the revolution of the Sun
21
What degree measure is the tilt of planet Earth?
23.5o
20o
20.5o
15o
22
Which observation about the Sun's path on June 21st is best supported by the diagram?
The sun's total daytime path is shortest on this date.
Sunrise occurs north of east.
The sun moves at a rate of 10o per hour.
Sunset occurs south of west.
23
If you see the sunset in the North West, then that means...
It is a summer late afternoon.
Kanye is coming.
It is a winter late afternoon.
It is a summer morning.
24
Which statement about the period of revolution of the planets is correct?
Planet Z has a longer period of revolution than Planet X
Planet Y has a longer period of revolution than Planet Z
Planet X has a longer period of revolution than Planet Y
The planets have equal periods of revolution
25
The gravitational pull between the sun and the Earth when it is aphelion distance away is...
less strong, therefore Earth moves slower
less strong, therefore Earth moves faster
stronger, therefore Earth moves slower
stronger, therefore Earth moves faster
26

Which two characteristics do all Jovian planets have in common?
small diameters and low densities
large diameters and high densities
small diameters and high densities
large diameters and low densities
30
The orbital path of these planets around Star A can best be described as having
an elliptical shape, with Star A at one focus point
the same rotation
a circular shape, with Star A at one focus
major axes of the same length
31
As you increase the distance between two foci points, the shape of the ellipse
gets bigger
gets flatter and wider
gets more circular
gets smaller
32

41 degrees N
Topic of Cancer
Tropic of Capricorn
The equator
33
