Up in the north during the winter when there is no sun, is there a moon?

Answer 1

From the north pole, you can see all of the sky north of the celestial equator. The sun disappears from the polar sky when it moves south of the equator on the autumnal equinox, and reappears when it crosses north at the vernal equinox.

Like the sun, the moon is visible from the north pole for the half of its orbit when it's above the equator. So it is seen continuously for about two weeks and then disappears for the next two weeks. In particular, the full moon close to the winter solstice is located close to the sun's position at the summer solstice, and will be in the sky all day long. Around the summer solstice, the positions are reversed and you can't see the full moon from the north pole.

Answer 2

Yes. Where the sun would be up all day above the artic circle at the summer solstice, the moon would be above the horizon at the winter solstice.

You can see this effect at any northern latitude. As summer arrives and the sun comes up further to the north, the moon rises further to the south. The opposite happens in winter, the moon rises further to the north as the sun rises further south.

The earth's axis causes it to be tilted away from or toward the sun at different times of the year, but the moon stays in the same orbit without changing as the earth tilts.

Answer 3

Yep. The moon goes above and below the equator as it orbits Earth, so it will be up for two weeks and down for two weeks viewed from the poles.
