- Annual meteor showers occur when the Earth passes through the orbital path of acomet. The intensity of these showers vary from year to year. Which of the following may bethe reason for this? Group of answer choices - Meteor showers are not caused by comet debris - Sun's temperature - en distribution of debris along comet's orbit - Earth's rotation axisOriginally 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 are 5 things a visitor to Saturn whould need to bring
- 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.
- Calculate the orbital period of a comet nucleus in the Oort cloud.Explain Comets?Which of the following statements about comets and asteroids is TRUE? Only asteroids collide with Earth All asteroids lie in a belt between Jupiter and Mars Comets are balls of ice and dust O Most of the trillions of comets in our Solar System have tails
