- 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 axisarrow_forwardOriginally 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?

- 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.)arrow_forwardWhat is the escape velocity from the surface of Callisto if its mass is 1.1 x 1023 kg and its radius is 2.4 × 10° km?

- suppose that the oort comet cloud contains 10^12 comets, with an average comet diameter of 10km. Calculate the mass of a comet 10km in diameter, assuiming that it is composed mostly of water ice (density of 1g/cm^3). Next calculate the total mass of the comet cloud. finally, compare this mass with that of the Earth and Jupiter.arrow_forwardCalculate the orbital period of a comet nucleus in the Oort cloud.arrow_forward
