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.
