Study Notes
The Solar System
- The solar system includes the asteroid belt between Mars and Jupiter, primarily composed of rocky objects.
- The Kuiper Belt extends past Neptune, containing icy bodies.
- The Oort Cloud is a vast, spherical region of icy comets, farthest from the Sun.
- Comets are composed of dust, rock, and ice, not maintaining fixed orbits around the Sun.
- Ganymede, a moon of Jupiter, is the largest moon in the solar system.
- The Sun accounts for 98.8% of the solar system's total mass, approximately 4.5 billion years old.
- Venus and Mercury are nearly perfect spheres, closer to the Sun, and have shorter orbital periods than Earth.
- Mars has the largest volcano in the solar system.
- Planets other than Earth are named after Greek or Roman deities.
Astronomy
- Astronomy uses refractor and reflector telescopes.
- Apollo 11 marked the first successful human landing on the Moon.
- Neutron stars and black holes are remnants of supernova explosions.
- Core-collapse supernovae occur during massive star life cycles.
- Thermal runaway supernovae are another type of explosion.
- Probes haven't yet landed on Jupiter or Saturn.
- The Andromeda Galaxy, a barred spiral galaxy, is the closest major galaxy to the Milky Way.
Earth and the Moon
- Earth rotates west to east, 150 million kilometers from the Sun.
- Earth's atmosphere is 78% nitrogen and 21% oxygen.
- Sunlight takes 8 minutes to reach Earth, traveling at approximately 300,000 kilometers per second.
- Proxima Centauri is the closest star to Earth, excluding the Sun.
- The Moon has no atmosphere, orbits Earth every 27 days, and reflects sunlight.
- The Moon experiences eight distinct phases in its cycle.
- A "blue moon" occurs when two full moons happen in the same month.
