SOLAR SYSTEM

Detailed explanation-1: -The planets Mercury, Venus, Earth, and Mars, are called terrestrial because they have a compact, rocky surface like Earth’s terra firma. The terrestrial planets are the four innermost planets in the solar system.

Detailed explanation-2: -The Inner Planets: The four inner planets are called terrestrial planets because their surfaces are solid (and, as the name implies, somewhat similar to Earth-although the term can be misleading because each of the four has vastly different environments).

Detailed explanation-3: -A terrestrial planet, telluric planet, solid planet, or rocky planet, is a planet that is composed primarily of silicate rocks or metals. Within the Solar System, the terrestrial planets accepted by the IAU are the inner planets closest to the Sun: Mercury, Venus, Earth and Mars.

Detailed explanation-4: -Statement 1: Mercury, Venus, Earth and Mars are known as inner planets. They have less number of moons or no moons. Statement 2: Jupiter, Saturn, Uranus and Neptune are known as outer planets. They have large number of moons and all have a ring system around them.

Detailed explanation-5: -Unlike the terrestrial planets that make up our inner solar system-Mercury, Venus, Earth, and Mars-the Jovian planets do not have solid surfaces. Instead, they are composed primarily of hydrogen and helium, with traces of methane, ammonia, water, and other gases in their atmospheres.

Detailed explanation-6: -Terrestrial planets are Earth-like planets made up of rocks or metals with a hard surface. Terrestrial planets also have a molten heavy-metal core, few moons and topological features such as valleys, volcanoes and craters.
