Study Notes
Solar System Planet Order
- The planets in our solar system, in order from the Sun, are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
- This order reflects the planets' distance from the Sun, with those closer to the Sun orbiting faster.
- The inner, rocky planets (Mercury, Venus, Earth, and Mars) are closer to the Sun than the outer gas giants (Jupiter, Saturn, Uranus, and Neptune).
- The asteroid belt lies between Mars and Jupiter.
- The farther a planet is from the Sun, the longer its orbital period.
- Note that Pluto, once considered the ninth planet, is now classified as a dwarf planet.
Mercury
- Closest planet to the Sun.
- Very small, rocky planet.
- Extremely hot temperatures on the sunlit side and frigid on the dark side.
- Virtually no atmosphere.
- Notable for extreme temperature variations.
- Characterized by numerous impact craters.
- Its lack of atmosphere leads to extreme temperature differences.
Venus
- Second planet from the Sun, similar in size and mass to Earth.
- Dense, toxic atmosphere composed primarily of carbon dioxide.
- Extremely high surface temperatures due to the greenhouse effect.
- Surface obscured by thick clouds of sulfuric acid.
- Rotates very slowly in the opposite direction to most other planets.
- Known for its extreme heat and atmospheric pressure.
- The extreme greenhouse effect causes extremely high surface temperatures.
Earth
- Third planet from the Sun; only known planet supporting life.
- Moderate temperature range, with liquid water crucial to life as we know it.
- Atmosphere composed mostly of nitrogen and oxygen.
- Moderate atmospheric pressure.
- Has a single, large moon.
- Supports a variety of life forms due to its moderate temperature and liquid water.
Mars
- Fourth planet from the Sun.
- Known for its reddish appearance due to iron oxide (rust) on the surface.
- Thin atmosphere, mostly carbon dioxide.
- Evidence of past water activity, raising possibility of past life.
- Polar ice caps, with seasonal variations.
- Two small moons.
- Frequent dust storms.
- Features evidence of past water activity, hinting at potential for past life.
Jupiter
- Fifth planet from the Sun, the largest in the solar system.
- Primarily composed of hydrogen and helium.
- Strong magnetic field.
- Numerous moons, including the four Galilean moons.
- Famous for its Great Red Spot, a giant storm.
- Known for its many moons, large size and gas composition.
- Its immense size and powerful magnetic field are notable features.
Saturn
- Sixth planet from the Sun, famous for its rings.
- Made primarily of hydrogen and helium.
- Numerous moons, with Titan being the largest.
- Spectacular ring system composed of ice and rock particles.
- Lower density than any other planet.
- Distinctive ring system is the most recognizable feature.
- Its low density relates to its composition, mostly hydrogen and helium.
Uranus
- Seventh planet from the Sun.
- Significantly smaller than Jupiter and Saturn.
- Composed primarily of ice, with some rock.
- Rotates on its side, with an unusual axial tilt.
- Faint ring system.
- Distinctive feature is its unusual axial tilt.
- Has a series of faint rings and a large number of moons.
- Its unique axial tilt sets it apart from other planets.
