Temperature on Planets
The diagram shows the planets of our solar system and their mean temperatures
(in degrees Celsius).
Mercury
167ºC
Venus
464ºC
Earth
15ºC
Mars
265ºC
Jupiter
2110ºC
Saturn
2140ºC
Uranus
2195ºC
Neptune
2200ºC
1. Complete the statement using < or > .
a. mean temperature of Mars _______ mean temperature of Jupiter
b. mean temperature of Earth _______ mean temperature of Mercury
c. mean temperature of Saturn _______ mean temperature of Neptune
List the planets that have the described mean temperature.
2. Mean temperature < −140°C
3. Mean temperature > −50°C
4. Mean temperature is warmer than Earth’s mean temperature.
5. Mean temperature is colder than Jupiter’s mean temperature.
6. Which planet has a mean temperature that is farther from 0°C , Mercury or
Uranus? Justify your answer.
7. Your friend orders the planets from greatest mean temperature to least
mean temperature. Your friend says this can be done by simply ordering the
planets according to their distance from the Sun. Is your friend correct?
Explain.

Common Core State Standard
Understand ordering and absolute value of rational numbers.
a. Interpret statements of inequality as statements about the relative
position of two numbers on a number line diagram.
b. Write, interpret, and explain statements of order for rational numbers
in real-world contexts.
c. Understand the absolute value of a rational number as its distance
from 0 on the number line; interpret absolute value as magnitude for
a positive or negative quantity in a real-world situation.
d. Distinguish comparisons of absolute value from statements about order.
