- 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.If the velocity of the Solar Wind about 4.0 x 10^2 km/s and the visible tail of a comet of 9.0 x 10^8 km long, how many days does an atom in the solar wind take to travel from the nucleus to the end of the visible tail? (note: 1 day= 86,400 sec) _______ daysExplain the light emission by meteorite?
- What is the evidence that suggests asteroids might have geologically active surfaces?A typical comet contains some 1013 kg of water ice. How many comets would have to strike Earth in order to account for the roughly 2×1021 kg of water presently found on our planet? (Hint: simple division) If this amount of water accumulated over a period of 500 million years, how frequently must Earth have been hit by comets during that time? (Hint: Calculate, on the average, how many comets hit the Earth per year during that time.)Why do we see comet Halley only every 76 years? Explain your reasoning.
