I've gotten into an amusing discussion with another individual on the topic of the apparent size of comets as seen in SOHO satellite images of Sungrazing or Sun-impacting comets. I won't go into the crackpot conspiracy theories I've heard, but will instead ask: why do these tiny comets appear so large in the images (relative to the Sun itself)? My own thoughts have led to two potential answers, but I'm still a little unsure. Here they are: 1) The comets reflect a great deal of intense light as a result of their proximity to the Sun and this results in pixel-bleeding on the CCDs. Thus, they appear much larger than they really are. 2) The comets disintegrate as a result of receiving so much solar radiation and the cloud of debris around them can become very large. I guess it could be a combination of both, too. Am I on the right track?
