Worksheet 62: Ellipse and Moon
1. The diagram below represents the elliptical
orbit of the Earth around the Sun.
STRIVE
2. The diagram below represents the orbit of a
spacecraft around the sun.
The eccentricity of the spacecraft's orbit is
A) more eccentric than the orbit of any planet in the
solar system
B) more eccentric than planets 300 million km from
the sun but less than those 100 million km from
the sun
C) less eccentric than planets with a density less
than 5 gm/cm 3
D) more eccentric than Earth's orbit but less
eccentric than Mars' orbit
Which equation should be used to find the
eccentricity of the Earth's orbit?
A) eccentricity =
5,000,000 km
299,000,000 km - 5,000,000 km
B) eccentricity =299,000,000 km
5,000,000 km
C) eccentricity = 299,000,000 km - 5,000,000
km
D) eccentricity = 5,000,000 km
299,000,000 km
3. Base your answer to the following question on
the diagram below, which represents the path of
a planet in an elliptical orbit around a star.
Points A, B, C, and D indicate four orbital
positions of the planet.
The eccentricity of the planet's orbit is approximately
A) 0.65
B) 1.55
C) 0.18
D) 5.64
4. What is the approximate eccentricity of the
ellipse?
A) 0.15 B) 1.4
FOR
C) 0.40 D) 0.73

5. An observer on the Earth measured and
recorded the slight changes in the apparent
diameter of the Moon for 2 months. A graph of
the data is shown below.
STRIVE
Which statement best explains the observation:
A) The distance from the Earth to the Moon
varies in a cyclic manner.
B) The Earth revolves around the Moon each
month.
C) The Moon actually increases and decreases
in size each month.
D) The apparent diameter of the Moon is
always greatest at the new-moon phase.
