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. In what year did the New Horizons probe reach Pluto? 2015 What are the two main reasons for a comet’s interesting behavior? Their composition, mostly ices, and their highly eccentric orbits. What is the Kuiper Belt? A collection of many small icy objects beyond the orbit of Neptune. What are the two basic types of meteorites? Stones or Stone Meteorites and Irons or Iron Meteorites. How are asteroids discovered? By taking extended time photographs and observing streaks relative to the fixed background stars. How does a comet eventually die? Comets eventually disint egrate afte r several passes close to the Sun. What is a KBO? A ‘KBO’ is an icy-rocky planetesimal sharing an orbit with many other similar objects, orbiting beyond Neptune. What is the difference between a comet and ...

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...

Which planet is the most massive? Jupiter Which planet type tends to be high mass? Jovian Which planet is the least massive? Mercury Which planet type tends to be low mass? Terrestrial Which planet type tends to be high-density Terrestrial Which planet type tends to be small? Terrestrial Which planet type tends to have many natural satellites? Jovian If Pluto were a planet, which type would it be, if you consider only its size? Terrestrial If Pluto were a planet, which type would it be, if you consider only its density? Jovian If Pluto were a planet, which type would it be, if you consider only its number of satellites? Terrestrial What were the three major components of the solar nebula? Rock and Metal, Hydrogen Compounds, Hydrogen and Helium Gas Which components exist in solid form inside the Rock/Metal condensation line? (By ‘inside’ we mean closer to the center or closer to the protosun.) Non...
