Study Notes
Comets and Asteroids
- The comet with the shortest orbit is Encke's Comet, taking 3.3 years to orbit the Sun.
- Comets are also known as "dirty snowballs" due to their icy middle and layer of black dust.
- Comets originate from the Oort Cloud, a region in the outer solar system.
Meteoroids and Meteors
- Meteoroids are small chunks of rock or metal that burn up in the Earth's atmosphere.
- When meteoroids enter the Earth's atmosphere, they burn up and are known as meteors or shooting stars.
- Meteors are also known as falling stars when they burn up in the Earth's atmosphere.
- Only a few meteors reach the Earth's surface as meteorites each year.
Asteroids
- Asteroids are found in the asteroid belt, an area between Mars and Jupiter.
- The largest asteroid in our solar system is Ceres.
- The second largest asteroid in our solar system is Vesta.
- Trojan asteroids are a group of asteroids that are near Jupiter's orbit.
- Asteroids that have left the asteroid belt and spun into other orbits are called Near-Earth Objects (NEOs).
- Halley's Comet is a type of short-period comet that takes less than 200 years to travel around the Sun.
Coma and Tails
- A cloud called a coma is created at the head of a comet when it gets close to the Sun, due to the Sun's heat vaporizing the comet's ices.
- Comets' tails are formed when the comet approaches the Sun and the Sun's heat vaporizes the comet's ices, creating a trail of gas and dust.
General
- Asteroids, comets, and meteors have in common that they are all small bodies in our solar system.
- Only a few meteorites reach the Earth's surface each year.
