SOLAR SYSTEM

Detailed explanation-1: -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-2: -The giant planets of the outer solar system (Jupiter, Saturn, Uranus and Neptune) are often referred to as ‘Jovian planets’.

Detailed explanation-3: -Jovian planets: Jupiter, Saturn, Uranus, and Neptune are called Jovian planets because they all are similar to Jupiter which is referred to as Jove, an ancient Roman god of sky and thunder. Jovian planets are also called gas giants as they do not have a solid surface like earth.

Detailed explanation-4: -Mercury and Venus are the only planets in our solar system without moons (i.e. they do not have any natural satellite).

Detailed explanation-5: -Earth and the other three inner planets of our solar system (Mercury, Venus and Mars) are made of rock, containing common minerals like feldspars and metals like magnesium and aluminum. So is Pluto. The other planets are not solid. Jupiter, for instance, is made up mostly of trapped helium, hydrogen, and water.
