What is the lowest latitude in which the moon can remain above or below the horizon for more than 24 hours?
About 61.3° north or south latitude.
Seems to me that since the Moon's orbit is inclined about 5.2° to the ecliptic, that
gives you 5.2° more outside of both polar regions where the moon can stay up or
stay down for more than 24 hours, and the same distance outside of the tropical
belt where the moon can appear directly overhead.
The Earth's axis is tilted at about 23.5 degrees to the plane of its orbit (plane of the ecliptic). So, that's why the answer is:
90 degrees minus 23.5 minus 5.2 = 61.3 degrees.
This latitude is sometimes called the "Lunar Arctic (or Antarctic) Circle". It's not so easy to define precisely as the Arctic Circle, but about 61.3 degrees is, near enough, the correct answer.

What is the relationship between a particular latitude and the angle of Polaris above the horizon at that latitude?
The angle of Polaris above the northern horizon is very nearly equal to your north latitude, within about 1/3 of a degree. So it's over your head when you stand at the north pole, it sits nominally on your north horizon when you stand anywhere on the equator, and if you're south of the equator, you can never see it at all.
What latitude on earth is a celestial pole 45 above the horizon'?
At 45 degrees north latitude, the north celestial pole appears 45 degrees above the northern horizon. At 45 degrees south latitude, the south celestial pole appears 45 degrees above the southern horizon.
What do the Arctic and Antarctic circles represent?
The Arctic Circle is the southernmost latitude in the Northern Hemisphere at which the sun can remain continuously above or below the horizon for 24 hours (at the June solstice and December solstice respectively) The Antarctic Circle is the northernmost latitude in the Southern Hemisphere at which the sun can remain continuously above or below the horizon for 24 hours.
How is the altitude of the North Celestial Pole above the northern horizon related to the observer's latitude?
The altitude of the North Celestial Pole above the northern horizon is equal to the observer's latitude. This means that the higher the observer's latitude, the higher the North Celestial Pole will appear in the sky. For example, an observer at a latitude of 45 degrees will see the North Celestial Pole 45 degrees above the northern horizon.
What is at 66 north latitude?
At 66 degrees north latitude, you are entering the Arctic Circle. This is the farthest point north where the sun can remain continuously above the horizon for 24 hours during the summer solstice and below the horizon for 24 hours during the winter solstice. This region is known for its extreme cold temperatures, polar day and night phenomena, and unique wildlife.
What determines the latitude of the Arctic Circle?
The Arctic Circle is the southernmost latitude in the Northern Hemisphere at which the sun can remain continuously above or below the horizon for 24 hours.
Why are there Arctic and Antarctic Circles?
The Arctic Circle is the southernmost latitude in the Northern Hemisphere at which the sun can remain continuously above or below the horizon for 24 hours (at the June solstice and December solsticerespectively).The Antarctic Circle is the northernmost latitude in the Southern Hemisphere at which the sun can remain continuously above or below the horizon for 24 hours (at the December solstice and June solstice respectively).
What is the importance of the Arctic and Antarctic Circles?
The Arctic Circle is the southernmost latitude in the Northern Hemisphere at which the sun can remain continuously above or below the horizon for 24 hours (at the June solstice and December solsticerespectively).The Antarctic Circle is the northernmost latitude in the Southern Hemisphere at which the sun can remain continuously above or below the horizon for 24 hours (at the December solstice and June solstice respectively).
What do the Arctic and Antarctic Circles show you?
The Arctic Circle is the southernmost latitude in the Northern Hemisphere at which the sun can remain continuously above or below the horizon for 24 hours (at the June solstice and December solsticerespectively).The Antarctic Circle is the northernmost latitude in the Southern Hemisphere at which the sun can remain continuously above or below the horizon for 24 hours (at the December solstice and June solstice respectively).
Significance of the Antarctic Circle?
The Antarctic Circle is the northernmost latitude in the Southern Hemisphere at which the sun can remain continuously above or below the horizon for 24 hours.

The number of degrees of arc that Polaris is above the horizon depends on what?
