What other objects could cause occultations? Would it be possible to observe the occultation of a star by another type of solar system object?
What other objects could cause occultations? Would it be possible to observe the occultation of a star by another type of solar system object? How about an ASTEROID? Problems: size, position of star, position of asteroid, brightness difference between them
The answer….YES!
