There are second obvious differences between terrestrial and jovian planets are their density. Terrestrial planets have high densities, but jovian planets have low densities. Taking Mars and Saturn as an example, according to a report about Mars, “With a mean density of 3.93 g/cm³, Mars is less dense than Earth, and has about 15% of Earth’s volume and 11% of Earth’s mass” (Williams, 2016). However, although Saturn’s volume is large, which is about 60 percent of Jupiter’s volume, it has the lowest mean density that is only 70 percent the density of water (Marley, Buratti, & Hubbard, 2016). As a result, by contrasting the density of these two planets, the data shows that the terrestrial planets are more dense than the jovian
