- Originally thought to be the realm of comets, over the past two decades we discovered that the Kuiper Belt region hosts also many other objects similar in size to Pluto (Figure 22). This seems to imply that there are two completely different types of objects in the region. Do you think that both types of objects formed in this region, or some of these may have migrated to this region at a later time? Briefly explain your reasoning.What is the defining property of the Trojan asteroids? Group of answer choices They have orbits that cross the orbit of the Earth. They have orbits beyond Neptune. They have a composition that is the most primitive of all asteroids. They are located within the orbit of Jupiter, 60 degrees ahead of or behind it. They were all named by the early Greeks.How many orders of magnitude do you need to grow in spatial scale (size) to form a planet? Let's take the extreme ends of this scale, from a dust particle of radius a = 10-6m to the gas giant Jupiter (you can round up its radius to the nearest ten to keep it simple). What else has this difference in order of magnitude? Maybe pick something that's not a length scale. Be creative!
