There is one part to this question. I need to know the km. Thank you!
If you saw Comet Halley when the comet was 0.8 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 ✕ 109 km.)
Suppose that the tail was not perpendicular to your line of sight. Is your first answer too large or too small?
You observe a comet 0.46 AU from Earth with a tail that is 1.7 degrees long. How long is the tail in AU?
How long is the tail in kilometers?
How many times could the U.S. fit along the length of the tail? (The width of the U.S. is 4,313 km.)
