SOLAR SYSTEM

Detailed explanation-1: -The terrestrial planets are the four innermost planets in the solar system. None of the terrestrial planets have rings, although Earth does have belts of trapped radiation, as discussed below. Among the terrestrials, only Earth has a substantial planetary magnetic field.

Detailed explanation-2: -All gas giant planets namely Jupiter, Saturn, Uranus and Neptune in the Solar System have rings, while the terrestrial planets like Mercury, Venus, Earth and Mars do not.

Detailed explanation-3: -It is likely that large rings couldn’t form on inner planets (Mercury, Venus, Earth, Mars) because the rings are made of frozen icy dust, and the sun is too hot this close to it for the rings to form. Additional fact: Mars has two moons, one of which is very close to the planet.

Detailed explanation-4: -With the exception of Pluto, planets in our solar system are classified as either terrestrial (Earth-like) or Jovian (Jupiter-like) planets. Terrestrial planets include Mercury, Venus, Earth, and Mars.

Detailed explanation-5: -After size, perhaps the most noticeable difference between the jovian and terrestrial planets involves moons and rings. The terrestrial planets are nearly isolated worlds, with only Earth (1 moon) and Mars (2 moons) orbited by any moons at all. In contrast, many moons and rings orbit each of the jovian planets.

Detailed explanation-6: -Of the terrestrial (rocky) planets of the inner solar system, neither Mercury nor Venus have any moons at all, Earth has one and Mars has its two small moons. In the outer solar system, the gas giants Jupiter and Saturn and the ice giants Uranus and Neptune have dozens of moons.
