Using technology or other resources, research the average distance that each planet is from the
sun (in kilometers). Once you have found the distance, create a chart showing each planet's
distance from the sun. The sun itself will not receive a label since it is your starting point. For
example, Mercury is located an average of 57,909,000 km from the sun, so on the chart, Mercury
would be labeled with a distance of 57,909,000. Use the example of the chart below to help you
get started:
Part 2
Convert each of the distances that you have recorded into scientific notation. List these on your
chart for this assignment.
Part 3
Answer the following questions using the data you have found. Show your work on all questions
as indicated.
A.
If a spacecraft was parked on Venus and needed to make a flight to Jupiter, how far
would it need to travel? (Assume both planets are aligned with the sun and are on the
same side of the sun.) Show your work and provide your answer in scientific notation.
7.785 E8 - 1.082 E8

=(7.785-1.082) E8
=6.703 E8
6.703 E8 need to travel from Venus to Jupiter.
B.
Mercury, Venus, and Earth are the three planets closest to the sun. Would their combined
distance from the sun be greater or less than the distance from the sun to Neptune?
Show your work and justify your answer.
Mercury, Venus, and Earth combined distance from the sun is,
5.7909 E7+1.082 E8+1.496 E8
=(0.57909+1.082+1.496) E8
=3.15709 E8
The distance from the sun to Neptune is 4.495 E9.
Mercury, Venus, and Earth combined distance from the sun
is less than
the
distance from the sun to Neptune.
C.
If Earth was 10 times farther away from the sun than it is now, which planet would it be
closest to? (Assume all the planets are aligned with the sun and are on the same side of
the sun.) Compare Earth's new distance to that planet. How far apart would they be in
standard notation? How far apart in scientific notation? Show your work.
If Earth was 10 times farther away from the sun,
1.496 E8
10=1.496 E9
Saturn is about 1.434 E9 km apart from sun.
So, If Earth was 10 times farther away from the sun
would be closest to Saturn.
D.
The space shuttle travels at about 28,000 km per hour. Using that information, estimate
how many hours it will take the shuttle to reach Saturn from Earth. (Assume both planets
are aligned with the sun and are on the same side of the sun.) Show your work. Convert
your answer into scientific notation if necessary.
The distance from Saturn to Earth
is
1.434 E9 - 1.496 E8
= 14.34 E8 - 1.496 E8
=(14.34-1.496) E8
=12.844 E8 =
1.2844 E9
Speed of the space shuttle is 28,000 km/h
1.2844 E9
/
2.8 E4 is about 4.5871 E4
It will take about 45,871 hours to reach Saturn from Earth.
