Question

Pluto's density is most similar to:

1) Saturn, but not Jupiter, Uranus, or Neptune.
2) the jovian planets.
3) the terrestrial planets.
4) moons of the jovian planets.
5) Mercury, but not Venus, Earth, or Mars.

Answer 1

Pluto's density is most akin to the moons of the jovian planets and the terrestrial planets, with a higher density than the gas giants due to its rock and ice composition.

Step-by-step explanation:

Pluto's density is most similar to the terrestrial planets and the moons of the jovian planets. Pluto has a density of 1.9 g/cm³, which suggests a composition similar to many outer-planet moons-a mixture of rocky material and water ice.

When compared to the gas giants like Jupiter and Saturn, with densities of 1.3 g/cm³ and 0.7 g/cm³ respectively, Pluto's density is considerably higher. Uranus and Neptune have higher densities than Saturn, at 1.3 g/cm³ and 1.6 g/cm³, indicating a different composition that includes more ice and rock than the larger gas giants.

The density of Pluto is most similar to the moons of the jovian planets. According to data from the New Horizons probe, Pluto has a density of 1.9 g/cm³, suggesting that it is a mixture of rocky materials and water ice. This composition is similar to many moons that orbit the giant gas planets in our solar system.
