Textbook Question
Chapter 12, Problem 52EAP
Comet Dust Accumulation. A few hundred tons of comet dust are added to Earth daily from the millions of meteors that enter our atmosphere. Estimate the time it would take for Earth to get 0.1% heavier at this rate. Is this mass accumulation significant for Earth as a planet? Explain.

1. Suppose you have an Oort cloud comet on an orbit with pericenter distance 10,000 AU, and apocenter distance 20,000 AU.
a. What are the semi-major axis and eccentricity of the orbit?
b. What are the specific energy (energy per unit mass), and specific angular momentum (angular momentum per unit mass) of the comet?
c. How fast is the comet moving at apocenter (relative to the Sun)?
Imagine that astronomers have just discovered a planet orbiting another star (other than the Sun), and they have reported the mass of the planet as 4.2 Jupiter-masses. Explain in a few words what this means.
A lot of asteroid and comet dust collides with Earth's atmosphere everyday. Assume that 500 tons of mass is added to Earth daily from the millions of meteors that enter our atmosphere. Estimate the time it would take for the Earth's mass to increase 0.2% with this impact rate. Is this mass accumulation significant to Earth as a planet.

- Since 1995, hundreds of extrasolar planets have been discovered. There is the exciting possibility that there is life on one or more of these planets. To support life similar to that on the Earth, the planet must have liquid water. For an Earth-like planet orbiting a star like the Sun, this requirement means that the planet must be within a habitable zone of 0.9 AU to 1.4 AU from the star.

- Why do we think that planets in our Solar System were not formed out of the gaseous disk by direct gravitational collapse? Planets are formed in disks. Disks rotate too fast to collapse gravitationally to form planets. In disks that are not massive enough, tidal gravity of the central star prevents the disk gas from collapsing. The material in the disk orbits close to the star. This makes the disk too hot, and pressure support prevented the disk from gravitational collapse. The gravity of the forming planets was not enough to accrete gas.arrow_forwardYou decide to go on an interstellar mission to explore some of the newly discovered extrasolar planets orbiting the star ROTOR.
