- What is the orbital period of a scattered disk object with perihelion at 40 AU and aphelion at 100 AU? ( 2Explain the light emission by meteorite?If you visited a planet in another solar system and discovered that it was heavily cratered, but its small moon was nearly crater free, why would that be a surprise? Speculate about what might have happened to those objects.
- What is the evidence that suggests asteroids might have geologically active surfaces?How deep would be the eclipse caused by Jupiter transiting in front of the Solar disk, as observed from a distant star?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,
