    Study Notes

    Asteroids

    • Asteroids are characterized by their small size and orbit around the Sun.
    • The first discovered asteroid was Ceres, discovered by Giuseppe Piazzi in 1801.

    Types of Asteroids

    • C-type asteroids are believed to be composed of clay and silicate rocks.
    • Multiple types of asteroids are mentioned, including C-type, S-type, and M-type, differentiated by composition and color.

    Unique Asteroids

    • Ceres is unique among asteroids due to its large size and spherical shape.

    Asteroid Composition

    • S-type asteroids are primarily composed of silicate rocks and metals.
    • M-type asteroids are thought to be composed of metal.

    Trojan Asteroids

    • Trojan asteroids are asteroids that share the same orbit as Jupiter and are stuck in a gravitational equilibrium with the planet.

    Meteoroids and Meteorites

    • A meteoroid is a small particle from space that enters Earth's atmosphere, whereas a meteorite is a piece of a meteoroid that survives entry into the atmosphere and lands on Earth.

    Comets

    • Comets are primarily composed of ice and dust.
    • Most comets originate from the Oort Cloud, a distant region of the solar system.

    Comet Types

    • Short-period comets originate from the Kuiper Belt and take less than 200 years to orbit the Sun.
    • Long-period comets originate from the Oort Cloud and take more than 200 years to orbit the Sun.

    Asteroids vs. Comets

    • Asteroids are primarily composed of rock and metal, whereas comets are primarily composed of ice and dust.
    • Asteroids orbit the Sun, while comets have highly elliptical orbits that bring them close to the Sun and then out to the outer solar system.

    Meteors

    • Meteors are small particles from space that enter Earth's atmosphere and burn up, producing a bright streak in the sky.

    Impact Consequences

    • A large asteroid impact would have more significant consequences than a large meteor strike due to the asteroid's larger size and mass.
    • A comet impact would have a more significant effect on Earth than an asteroid or meteor impact due to the comet's high speed and large size.
