The terrestrial planets—Mercury, Venus, Earth, and Mars—are characterized by their rocky surfaces, dense compositions, and smaller sizes compared to the Jovian planets. These inner planets have solid crusts, relatively thin atmospheres, and fewer moons. In contrast, the Jovian planets—Jupiter, Saturn, Uranus, and Neptune—are primarily composed of gases like hydrogen and helium, feature large sizes, thick atmospheres, and numerous moons. Their substantial gaseous envelopes and gravitational pull enabled them to capture and retain massive amounts of gas from the solar nebula during formation. According to the nebular theory, the differences between these two groups are explained by their distance from the Sun, which influenced temperature and material accumulation. The cooler outer regions allowed the Jovian planets to amass extensive gaseous layers, while the hotter inner regions favored the formation of rocky planets with less gaseous material.
Paper For Above instruction The distinctions between terrestrial and Jovian planets highlight the diversity of our solar system's formation processes. Terrestrial planets, formed in the warmer inner regions of the protoplanetary disk, experienced high temperatures that prevented them from capturing significant amounts of gas, leaving them primarily rocky and metal-rich (Lissauer & De Pater, 2013). Their dense compositions contributed to their solid surfaces, which are easily observable and studied. Conversely, the Jovian planets formed in the cooler outer regions where volatile compounds such as hydrogen and helium could condense into gas, enabling these planets to grow massive gas envelopes through a process known as gas accretion (Pollack et al., 1996). This process began when solid cores formed first by accretion of ice, rock, and metal, then rapidly captured surrounding gases once their gravity was sufficient, resulting in the giants we observe today (Pollack et al., 1996). The nebular theory postulates that the temperature gradient within the solar nebula influenced the planet formation process. High temperatures in the inner zones prevented volatile gases from condensing, leading to rocky planets with little gaseous material. Meanwhile, further from the Sun, lower temperatures allowed gas and ice to condense onto forming planetary cores. The accumulation of gases was facilitated by the planets’ increasing gravitational pull, which enabled them to draw in and retain substantial gaseous
