    Study Notes

    Solar System Overview

    • The Solar System is a gravitationally bound system consisting of the Sun and various celestial objects that orbit it.
    • Key components include the Sun, planets, moons, dwarf planets, and small bodies.

    The Sun

    • Positioned at the center of the Solar System, the Sun is a nearly perfect sphere composed mostly of hydrogen (approximately ¾ of its mass), with helium being the second most abundant element.
    • Represents 99.86% of the total mass in the Solar System.
    • Nuclear fusion occurs in the Sun’s core, converting hydrogen to helium and releasing vast amounts of energy in the form of electromagnetic radiation.

    Planets

    • Planets orbit the Sun in a direction consistent with Earth's orbital plane.
    • Mercury: Closest planet, characterized by a heavily cratered surface.
    • Venus: Second planet, known for a dense atmosphere and significant volcanism.
    • Earth: The third planet, unique for its liquid surface water and supportive atmosphere.
    • Mars: Fourth planet, featuring volcanoes, rift valleys, and polar ice caps.

    Terrestrial vs. Giant Planets

    • Terrestrial planets (Mercury, Venus, Earth, Mars) have dense, rocky compositions.
    • Giant planets are categorized further: Jupiter and Saturn are gas giants, while Uranus and Neptune are classified as ice giants, consisting largely of volatile compounds.

    Notable Features of the Gas Giants

    • Jupiter: Fifth planet, known for its distinct atmospheric bands and the Great Red Spot, a massive storm.
    • Saturn: Sixth planet, recognized for its pronounced rings and fainter atmospheric bands.
    • Uranus: Seventh planet, notable for its cyan color due to methane in its atmosphere.
    • Neptune: Eighth planet, features vibrant weather patterns unlike its neighbor Uranus.

    Moons and Satellites

    • Most planets have natural satellites (moons); Earth has one significant moon, while Jupiter boasts 95 known moons.
    • Saturn has 146 moons, with Titan being the largest and the only moon with a substantial atmosphere.

    Dwarf Planets and Small Bodies

    • Dwarf planets like Ceres (largest in the asteroid belt) and Pluto (largest in the Kuiper belt) are key players.
    • The asteroid belt lies between Mars and Jupiter, containing numerous rocky and metallic objects.
    • The Kuiper belt extends beyond Neptune, filled with small, icy bodies.

    Formation of the Solar System

    • The nebular hypothesis is the leading theory for the Solar System's formation, positing that it originated from the gravitational collapse of a giant molecular cloud.
    • The early Solar System, comprised mostly of hydrogen and helium, began to spin and heat up due to gravitational forces.
    • A protoplanetary disc formed, and planets were created through the process of accretion from dust grains.

    Planet Formation

    • Inner Solar System's rocky planets formed from metal and silicate compounds due to higher temperatures, while icy bodies beyond the frost line coalesced into the giant planets (Jupiter and Saturn) as they attracted significant amounts of hydrogen and helium.
    • The young Sun's solar wind expelled gas and dust, affecting the growth of planets, particularly Uranus and Neptune.
    • Protoplanets merged to form terrestrial planets, but their growth was hindered due to the rarity of rocky materials in the primordial nebula.

    Summary Points

    • Ceres and Pluto are prominent dwarf planets representing largest bodies in their respective regions.
    • Additional recognized dwarf planets include Haumea, Makemake, Quaoar, and Orcus.
    • Extreme trans-Neptunian objects, such as Eris and Sedna, have high orbital eccentricities, likely due to gravitational interactions with gas giants.
