The density graph, Figure 4.1d, shows something different. Mercury, Venus, Earth and Mars have
higher densities while the larger, massive planets along with Pluto and Eris all hive lower
densities. The higher densities are because Mercury. Venus, Barth, and Mars are made mostly of
rock and metal while the lower-density objects, Jupiter. Saturn, Uranus, and Neptune, are made
largely of gases and liquids. Being so far from the Sun, Pluto and Eris are composed partly of
ice.4. Based on the comparisons you have made, have any objects been grouped together every
time? How many groups are there?7. Examine the data in Table 4.1 comparing the orbital radius
(distance from the Sun) of each object. Which group is closer to the Sun? Which group is further
from the Sun?8. By now, you may have noticed that there are two major groups of planet
classification. Label each group and list the members of each of your groups: List what properties
from the data table and bar graphs that the objects in each of your groups have in common. 9. Is
(are) there a (any) objects(s) that do not seem to fit into a group? Which objects? Have you heard
about a fairly recent decision made about one of these objects? Did this exercise help clarify the
reason for the decision? 10. State whether or not you agree with each student and why or why not.
Student 1 Pluto and Eris should be in a group with Earth and the other objects like Earth (the
Terrestrial planets) because they are small, of low mass, do not have very many moons, and have
longer rotation periods. Student 2 No, Pluto and Eris should be in a group with Jupiter and the
other objects like lupiter (the Jovian planets) because they have lower density and are far from
Sun. Student 3 Maybe Pluto and Eris do not fit into either category and should be considered a
different type of object than the Ierrestrial or Jovian planets? Small, low mass, lower density
objects with few or no moons and longer rotation periods that are even farther from the Sun than
the Jovian planetsItRIE I 1 Colar Guetom Oiviont Hats Pigure 1.1a, 4.1c, and 4.1d show bar

others that even register on the graph. Perhaps at this point Jupiter, Saturn. Uranus, and Neptune
could be considered a group of large and massive planets while Earth and all the others could be
called small and less massive planets.
