B. gaseous
C. few moons
D. low density
E. slow rotation

Answer 1

The outer planets in our solar system are gaseous, have few moons, low density, and slow rotation.

Step-by-step explanation:

The outer planets in our solar system are Jupiter, Saturn, Uranus, and Neptune. These planets have several characteristics that differentiate them from the inner planets.

• Gaseous: The outer planets are predominantly made up of gases, such as hydrogen and helium, and have very little solid surface.
• Few moons: The outer planets generally have a larger number of moons compared to the inner planets. For example, Jupiter has 79 known moons, while Saturn has 82 moons.
• Low density: The outer planets have lower densities compared to the inner planets. This is because their composition is mostly gas rather than rock and metal.
• Slow rotation: The outer planets have slower rotation rates compared to the inner planets. For instance, a day on Jupiter lasts about 10 hours, while a day on Neptune lasts about 16 hours.
