Chapter 21, Problem 14P
The smallest detail visible through Earth-based telescopes is about 1 arc second in diameter. What linear size does that correspond to on Mercury when Mercury is at a distance of 1 AU? Can Caloris Basin be resolved? (Hint: Use the small-angle formula, Eq. 3-1.) (Note: 1 AU is 1.5 × 108 km.)

In the previous lab, we calculated the area in between Mars' and Jupiter's orbit to be ~1.6e18 km2. Since there are roughly 750,000 asteroids, how much area (in km2) is available for one asteroid? Use this calculation to argue whether you are likely (or not) to hit an asteroid while flying through the asteroid belt.
(Hint: To answer the first part of the question, find the area per asteroid)

At an average opposition, the Earth and Mars are separated by 0.52 AU. Suppose an astronomer
observes Mars at opposition and that seeing blurs the images to a resolution of 1.0 seconds of arc.
What is the smallest surface feature the astronomer would be able to resolve on Mars? How does
this size compare with the diameter of Mars?
