Dwarf Planets
Where can dwarf planets be found?
The Kuiper Belt/ in between the orbits of Mars and Jupiter
Where can the Kuiper Belt be found?
The outer solar system
True or False: A meteor is a rocky body that travels in space
False
What do asteroids orbit?
The Sun
True or False: Comets originate in the asteroid belt
False
The first dwarf planet to be found
What is pluto?
What are comets in the Kuiper Belt called?
short period comets
What are the three types of Meteorites?
Stony, Iron, and Stony- Iron meteorites
What are the asteroids in the asteroid belt called?
Main-Belt Asteroids
Part of the Comet that is composed of ice and dust
Nucleus
True or False: Dwarf planets have a strong surface gravity
False
Describe the Oort cloud.
A spherical region that surrounds the solar system and extends halfway to the nearest star.
What causes meteoroids to glow
Friction
Where are Trojan Asteroids located in space?
In the orbits of Jupiter and Neptune
This part of a comet can be millions of kilometers long
dust tail
Why aren't dwarf planets regular planets
They are too small to have cleared other bodies out of its orbit around the sun.
How do comets form in the Oort Cloud besides collisions?
When an object is disturbed by the gravity of a nearby star.
Name 2/4 of the places meteoroids come from
Asteroid Belt, Mars, the moon, and comets
What are the orbital periods of the asteroids in the asteroid belt?
3 to 8 years
Fill in the Blank: A comet follows a highly ________
orbit around the sun.
Elliptical
Name the four dwarf planets that have dwarf planets that have been discovered outside the orbit of Neptune.
Pluto, Eris, Haumea, Makemake
How big is the Kuiper belt?
55 AU/ 8,250,000,000 km
Name the difference between meteors, meteorites, and meteoroids
A meteoroid is a fragment from an asteroid that travels through space. It becomes a meteor when it falls through earth's atmosphere and burns up because of friction. When it lands on earth, it is a meteorite.
What do small, rocky asteroids appear to be?
Piles of rock loosely held together by gravity
How do comets originate in the Kuiper Belt originate
collisions between KBOs produce fragments that become comets
