Is there a day time star pattern?
There IS a daytime star pattern, and it changes all the time. If you want to know what (today’s) daytime star pattern looks like, just wait 6 months and then go out at night. The constellations change with the seasons. Consider: when you go out at night and look at the stars, you are looking in the direction “away from the sun.” But as the earth moves around in its orbit, the “away-from-the-sun” direction constantly changes, pointing to a different direction in the universe. This means the constellations you see in January are distinctly different from the constellations you see in July. Meanwhile, if you look at the sky in the daytime, you are gazing in the “toward-the-sun” direction. Draw a diagram of the earth orbiting the sun, and draw arrows showing your gaze direction, and you’ll see that the January’s “toward-the-sun” direction matches July’s “away-from-the-sun” direction. So the January’s daytime star pattern is the same as July’s nighttime star pattern.
