Final answer:
Jupiter is 318 times more massive than Earth and has a diameter 11 times larger. Saturn, Uranus, and Neptune, the other outer planets, are significantly less massive than Jupiter but also have substantial masses. Each has unique characteristics, such as atmospheric composition and magnetic fields.
Step-by-step explanation:
Jupiter's mass is significantly larger than Earth's, with Jupiter having enough mass to create 318 Earths. In terms of size, Jupiter's diameter is approximately 11 times greater than that of Earth, and about one-tenth the diameter of the Sun. When comparing it to the other outer or jovian planets, Saturn has about 25% of Jupiter's mass, while Uranus and Neptune have only 5%.
Despite being made mainly of light gases such as hydrogen and helium, Jupiter's average density is 1.3 g/cm³, which is more than the density of water but much lower than Earth's density. The atmospheric compositions, magnetic fields, and internal heat of the outer planets also vary significantly; Jupiter, for example, has the strongest magnetic field and largest magnetosphere among the planets.
