A:
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.

- Suppose the average mass of each of 20,000 asteroids in the solar system is 1017 kg. Compare the total mass of these asteroids to the mass of Earth. Assuming a spherical shape and a density of 3000 kg/m3, estimate the diameter of an asteroid having this average mass.The planet Uranus was discovered in 1781, and Neptune, the next planet outward from the Sun, was discovered in 1846. Imagine you're an astronomer in 1846, and you start wondering if there's another planet out beyond Neptune. You decide to try and discover its existence using the same method that was used for Neptune. How will you do this? Group of answer choices You'll recruit a large number of astronomers to use their telescopes to carefully scan the sky in directions that are far from the ecliptic. The regions around the north and south celestial poles will probably be the best "hunting grounds" for the new planet. You'll examine Uranus and Neptune very carefully, on every clear night, for several years, to see if you can find any evidence that sunlight has been reflected off of the `new' planet, then off of Uranus or Neptune, before arriving on Earth. On rare occasions when Neptune passes in front of the Sun, as seen from Earth, you'll look carefully at the Sun (with a safe…Assume there are a million asteriods 1 kilometer across or larger in the asteroid belt. Assume all asteroids are perfectly spherical. 1) If a million asteroids 1-kilometer across were all combined into one spherical object, how big would it be across? 2) How many 1-kilometer diameter asteroids would it take to make an object as large as Earth?
- If you were to record the spectrum of Saturn as well as the A ring, you would find light from one edge of the rings redshifted and light from the other edge blueshifted. If you observed a spectral line at a wavelength of 505 nm, what difference in wavelength (in nm) should you expect between the opposite edges of the rings? (Hints: The radius of the edge of the A ring is 136,500 km. Use the formula for orbital velocity,1The transit method is used to detected exoplanets by measuring the reduced starlight caused by the planet passing in front of its host star. Say you measure multiple transits of the same exoplanet. What does the time in between the transits represent? Group of answer choices - Orbital period - Semi-major axis - Ecentricity - Planet's mass
- In the Transit method for detecting exoplanets, how many dips of light from the star need to be detected for it to be a successful detection of an exoplanet?If you were to record the spectrum of Saturn as well as the A ring, you would find light from one edge of the rings redshift and light from the other edge blueshift. If you observed a spectral line at a wavelength of 525 nm, what difference in wavelength (in nm) should you expect between the opposite edge of the rings? (Hint: The radius of the edge of the A ring is 136,500 km. Use the formula for orbital velocity and the formula for the Doppler shift.) _______ nmFor the following light curve, which of the answers best illustrates the orientation of the exoplanet and its host star during the dip at Time 3?
