SOLAR SYSTEM DEBRIS QUIZ


  1. How do we think Earth’s Moon formed?
The Moon resulted from the impact of a Mars sized object with Earth. Much of the ejected material formed the Moon.
  1. In what year did the New Horizons probe reach Pluto?
2015
  1. What are the two main reasons for a comet’s interesting behavior?
Their composition, mostly ices, and their highly eccentric orbits.
  1. What is the Kuiper Belt?
A collection of many small icy objects beyond the orbit of Neptune.
  1. What are the two basic types of meteorites?
Stones or Stone Meteorites and Irons or Iron Meteorites.
  1. How are asteroids discovered?
By taking extended time photographs and observing streaks relative to the fixed background stars.
  1. How does a comet eventually die?
Comets eventually disintegrate after several passes close to the Sun.
  1. What is a KBO?
A ‘KBO’ is an icy-rocky planetesimal sharing an orbit with many other similar objects, orbiting beyond Neptune.
  1. What is the difference between a comet and a meteor?
A comet is an asteroid-sized chunk of rock and ices in orbit around the Sun while a meteor is a small chunk of debris burning up in the Earth’s atmosphere.


What is the difference between a meteoroid, a meteor and a meteorite?
·         A meteoroid is a piece of debris in space. A meteor is a piece of debris burning up in Earth’s atmosphere and a meteorite is a chunk of debris that reaches the Earth’s surface.



·         What is a meteor shower?
A meteor shower occurs whenever the Earth passes through the meteoroid debris left behind by a comet. The result is that more meteors will occur during that time.

What are the two primary sources of comets?
·         The Kuiper Belt and the Oort Cloud

How do the coma and tail of a comet form?
·         Material from the comet nucleus is liberated by the heat of the Sun, some of which is blown away by the solar wind.


What is the name given to the theory that best explains the origin of our Moon?
·         Large Impact Theory


How crowded is the Asteroid Belt? Do spacecraft have trouble traveling through it?
·         In the asteroid belt, asteroids are separated from each other by millions of miles. By human standards, the asteroid belt is not crowded at all. Spacecraft would be able to pass through the asteroid belt with very little chance of colliding with an asteroid.

What are the two basic types of meteorites?
·         Stones or Stone Meteorites and Irons or Iron Meteorites.

What is the name of the largest known asteroid?
·         Ceres

Extra Solar Planets Question and Answer

Drag the phase slider left and right to move the planet into and out of transit mode. The normalized flux (relative amount of star light reaching an observer on Earth) when the planet is off to the side (not transiting) is _________ while the normalized flux when the planet is transiting is __________. (Hint: examine the plot at the top of the applet while you move the phase slider. The number you are looking for is on the left of the plot.) 1.000, 0.990 Now, decrease the planet size by sliding the Planet Properties ‘radius’ slider to the left until it is one-tenth (0.100) the radius of Jupiter. For this configuration, the normalized flux (relative amount of star light reaching an observer on Earth) when the planet is off to he side (not transiting) is ________ while the normalized flux when the planet is transiting is __________. 1.00000, 0.99990 Referring to the two questions above, the transit detection method relies on the difference between the flux when the pl...
