If you saw Comet Halley when the comet was 0.9 AU from Earth and you observed a visible tail 4 degrees long, how long was the tail in kilometers? (Hint: Use the small-angle formula.) (Note: 1 AU = 1.5 x 109 km.) km Suppose that the tail was not perpendicular to your line of sight. Is your first answer too large or too small? too small too large
