Students have asked these similar questions
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.
Why is the composition of a comet typically dominated by volatile materials (frozen ices)?
choose one of the following:
a.
rock and metal could not condense out of the solar nebula at extreme distances from the sun
b.
most of the metal in the solar system is locked up inside the terrestrial planets
c.
metals are not stable in the outer solar system
d.
elements that form ices (as opposed to rock & metals) are more abundant in our solar system
The Solar Nebula model introduces the concept of ‘frost line’. Where are asteroids and comets found with respect to this frost line?
How is their location connected to their composition?
