How do you explain this, /x/tards?

Comet star trails freak me the fuck out. Not a flat earth proponent but they make literally no sense.

What don’t you understand? This picture was taken north of the equator, south of the meridian facing almost west, a little to the north.
I can tell it’s in the Sonoran desert because of the Mexican jumping cactus.
What are you confused about?

The comet is supposedly moving retards and is a lot closer. It literally shouldn’t be similar to a star.

The comet IS moving. Over the course of a week or weeks, if you looked at it every night, you would notice that it was moving against the background stars. This is not visible in the few hours of a startrail exposure, though. All you can really see there is the movement of the Earth slowly turning your camera.

I am an old guy -- once in my life there was a very faint comet that passed very close to the Earth -- it was small, and old enough that it was not spraying dust and gas everywhere to make a tail. All you could see was a very faint blur if you sort of squinted and didn't stare straight at it too hard. It was so close that if you watched it all night, it moved 5-6 degrees against the background stars during the one night it was visible to the naked eye. For reference, the full moon is about half a degree -- so if the sky somehow had a giant clock face printed on it, the comet moved, relative to the stars, about half the speed that the hour hand would have. And that was a blisteringly fast comet, most stay visible for weeks, slowly moving across the background stars.

Spam filter won’t let me say what I want (not surprised). The comet is losing mass away from the sun in a near vacuum. And a lot of them have specific orbits. Like Haleys comet. If there was an example of a comet that passed a star trail during the night, perhaps that’d be more convincing.
