It is a very interesting video. But I have a question. Why this asteroid appears as a line? Normally they appear as a point passing by the sky. Perhaps this asteroid is like a comet. Is it possible?
Regards.
Hi,
The reason for the lines is that the video is infact series of photographs, each made with certain exposition (don't know the exact, but lets say 5 seconds). In each exposition (photo) the asteroid has moved. That's why there are lines.
