why can't we see comets at night?

Answer 1

My father, born in 1891, was a young man when Comet Haley made a very close pass to Earth, he told me it was visible in daylight. . That has to be very unusual.
Normally comets are visible only at night.
Comets are a rare phenomenon and though you are likely to see a few during a lifetime, you can't go out and see one with the naked eye very often.
I am over sixty and have seen only three without use of magnification, such as a telescope. They are newsworthy so if one passes close, you will hear about it in time to plan your opportunity to see it.
They have large irregular orbits, usually elliptical, visit us infrequently and on a schedule that makes close passes rare indeed.

Answer 2

I used to think other wise, the comets are best seen at night in the direction of the sun set.

Answer 3

Comets are fairly rare so on any given night, you have a very slim chace of seeing one.

I can assure you, though that you will NEVER see one during the day.

Answer 4

shouldnt this be in space and astronomy
