1. Large Size and Mass: Jovian planets are significantly larger and more massive than terrestrial planets. They are primarily composed of gas and ice, rather than solid rock.
2. Low Density: Due to their gaseous composition, jovian planets have a much lower density than terrestrial planets.
3. Many Moons: Jovian planets all have a significant number of moons orbiting them. These moons range in size from small, rocky bodies to large, icy worlds.
