Within the Solar System, four Jovian planets exist - Jupiter, Saturn, Uranus and Neptune. The terrestrial planets are the four innermost planets in the solar system. A terrestrial planet, telluric planet, or rocky planet is a planet that is composed primarily of silicate rocks or metals. The Moon is similar, but has a much smaller iron core. All those planets found within the Inner Solar System - Mercury, Venus, Earth and Mars - are examples of terrestrial planets. During the creation of the solar system, there were likely more terrestrial planetoids or very large asteroids, which probably merged or were destroyed. Thus, terrestrial planets can be described as planets that are earth-like in nature, meaning those that are similar in composition . These four planets are composed primarily of rock and have solid surfaces. In fact, all the terrestrial planets emit infrared light from their surfaces. What three conditions must an object meet to be considered a planet? Which of these conditions do Pluto and Ceres fail? The terrestrial planets must have been warmer and more volcanically active when they were younger. The terrestrial planets, to scale The four terrestrial planets plus the Moon (often considered an honorary terrestrial planet), compared in size and very roughly in color: Mercury, Venus, Earth, the Moon, and Mars. Currently, the Sun's magnetic field is not sufficiently strong to account for the proposed .
