True. But since it is difficult to judge the distance to the bolide, it is
equally as difficult to judge the size of the bolide. Saying it is the
size of a grapefruit implies you know accurately know the distance to the
object, which as I already pointed out, is extremely difficult to do at
night from a single observation.
