Study Notes
Terrestrial and Jovian Planets
- Terrestrial planets include Mercury, Venus, Earth, and Mars; they are characterized by rocky compositions.
- Jovian planets are composed mainly of gas and consist of Jupiter, Saturn, Uranus, and Neptune.
Solar System Order
- The order of the planets from closest to the sun to the furthest is: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune.
Characteristics of Planets
- Jovian planets are not rocky but are predominantly gas, distinguishing them from terrestrial planets.
- Terrestrial planets are solid and rocky in nature, contrasting with the gaseous composition of Jovian planets.
Nebula
- A nebula is defined as a cloud of dust and gas in space, serving as a nursery for new stars and planetary systems.
Influence of Sun on Planet Formation
- Proximity to the sun in the inner solar system resulted in high temperatures, allowing only metals and silicate minerals to solidify, leading to the formation of rocky terrestrial planets.
- In the colder outer solar system, gases and ices could condense, enabling the formation of gas giants or Jovian planets.
