    Study Notes

    Solar System

    • The Asteroid Belt is located between Mars and Jupiter, primarily containing rocky objects.
    • The Kuiper Belt, beyond Neptune's orbit, is composed mainly of icy bodies.
    • The Oort Cloud, the outermost region, is a spherical cloud of icy comet nuclei, the source of most long-period comets.
    • Comets are made of dust, rock, and ice.
    • The Solar System's largest moon, Ganymede, orbits Jupiter.
    • The Sun is approximately 4.5 billion years old and comprises about 98.8% of the Solar System's mass.
    • Venus and Mercury, closer to the Sun than Earth, have shorter orbital periods and are the roundest planets in the solar system (nearly perfect spheres).
    • Mars hosts the largest volcano in the Solar System.
    • All planets (excluding Earth) are named after Greek and Roman deities.

    Astronomy

    • Telescopes are categorized into refractor and reflector types.
    • Apollo 11 was the first mission to land on the moon.
    • A supernova, a massive stellar explosion, can result in neutron stars or black holes.
    • Core-collapse supernovae occur in the final stages of massive stars (at least eight times the Sun's mass).
    • Thermal runaway supernovae are another type of stellar explosion.
    • No probe has yet landed on Jupiter or Saturn.
    • The Andromeda Galaxy, a barred spiral galaxy, is the nearest major galaxy to the Milky Way, approximately 2.5 million light-years away.

    Earth and the Moon

    • Earth rotates from west to east and is 150 million kilometers from the Sun.
    • Earth's atmosphere is roughly 78% nitrogen and 21% oxygen.
    • Sunlight takes about 8 minutes to reach Earth (traveling at 300,000 km/s).
    • Proxima Centauri is the closest star to Earth (besides the Sun).
    • The Moon has no atmosphere, orbits Earth every 27 days, and reflects sunlight for visibility.
    • There are 8 main phases in the Moon's cycle.
    • A Blue Moon occurs when there are two full moons in a single calendar month (happens roughly every 2.7 years).
