The jovian (giant) planetsGroup of answer choiceshave satellite systems with less than 4 moons.are all much more dense than any of the terrestrials planets.all have rings around their equators.all spin slower than the earth.all lie less than 5 AU from the Sun.

The correct answer is "all have rings around their equators."

Here's why:

1. The Jovian planets (Jupiter, Saturn, Uranus, and Neptune) all have more than 4 moons. For example, Jupiter has 79 known moons and Saturn has 82.

2. The Jovian planets are not more dense than the terrestrial planets. In fact, they are less dense. Terrestrial planets like Earth are made up of heavy metallic rocks, while Jovian planets are largely composed of lighter elements like hydrogen and helium.

3. All Jovian planets do have rings around their equators. While Saturn's rings are the most famous, Jupiter, Uranus, and Neptune also have ring systems.

4. The Jovian planets do not all spin slower than the Earth. Jupiter, for instance, has the shortest day of all the planets, rotating on its axis once every 9.9 Earth hours.

5. The Jovian planets do not all lie less than 5 AU from the Sun. An AU (astronomical unit) is the average distance from the Earth to the Sun. Jupiter, the closest of the Jovian planets, is 5.2 AU from the Sun. Saturn, Uranus, and Neptune are even further away.
