Well actually, ALL constellations are circumpolar, but we use the word to mean
stars and constellations that are close enough to the poles of the sky that they
never get low enough to set below the horizon.
Any star that's within (your latitude) degrees of the pole does that.
If you're at the north or south pole, every star that's within 90 degrees of
the celestial pole is 'circumpolar'. That is, whenever it's dark and clear, you
see exactly half of the whole sky, and it's always the same half no matter
what time it is. Every star in your half of the sky makes a circle around the
point directly over your head. No star in your sky ever rises or sets, and
you never see any star that's in the other half of the sky.
What else can I help you with?
Which must be true of circumpolar constellations at the South Pole?
Circumpolar constellations are always visible in the night sky from a specific location, such as the South Pole, as they never set below the horizon. At the South Pole, all circumpolar constellations can be seen at some point during the year, as they revolve around the celestial point directly above the Earth's axis.
Where would you see the most circumpolar stars?
At the North Pole, and at the South Pole.
What southern circumpolar constellation that contains the steller south pole?
Octans (the octant).
Why aren't all constellations visible all year?
Circumpolar constellations are visible all year long, depending on where you are viewing them from. At the north pole, or the south pole, some constellations are visible year-round, these are the circumpolar constellations. On the equator, there are no circumpolar constellations because of the earths rotation, that is why circumpolar constellations are at the "poles". Some of the circumpolar constellations can also be viewed from other parts of the same hemisphere, such as the big dipper and the little dipper, although they are circumpolar, they are also seen in other parts of the northern hemisphere. Circumpolar constellations in the northern hemisphere, will never be seen at the south pole, and vice versa. I hope this helped.
What is a star that never sets at latitude?
Stars near the north celestial pole and the south celestial pole become "circumpolar" at high latitudes. They "circle around the pole". For example, the star Polaris never sets anywhere in the northern hemisphere. Constellations like the Big Dipper, Draco or Cassiopeia are "circumpolar" north of about 30 degrees north latitude. While there is no "south pole star", a constellation such as the Southern Cross is circumpolar south of about 40 degrees South.
Where are circumpolar constellations located?
For example, if you live at a latitude of 50° north, the circumpolar stars will be all stars that are up to 50° around the celestial north pole. As another example, if you live at a latitude 30° south of the equator, the circumpolar stars will be all those that are in a circle up to 30° around the celestial south pole.
Where are circumpolar constellations visible?
Anywhere, except right at the equator. For example: Somebody who lives 10 degrees south of the equator will see a region with a radius of 10 degrees, around the south pole of the sky, as circumpolar.
Southern circumpolar constellation that contains the stellar south pole?
The southern circumpolar constellation that contains the stellar south pole is called Octans. It is a faint constellation located close to the south celestial pole, making it useful for navigation in the Southern Hemisphere. Octans is named after the octant, a navigational tool used for determining latitude that was the precursor to the modern sextant.
A southern circumpolar constellation that contains the stellar south pole?
The southern circumpolar constellation that contains the stellar south pole is Crux, also known as the Southern Cross. It is a prominent asterism in the southern hemisphere sky and is easily recognizable by its distinctive shape of four bright stars. Due to its proximity to the celestial south pole, Crux remains visible all year round in the southern sky.
How many constellations are circumpolar?
There's no answer to this question, because the definition of circumpolar depends on where you are. If you're at the pole, all the constellations you can see are circumpolar. If you're on the equator, there are no circumpolar constellations.
If you were standing on the north pole how many circumpolar stars would you see?
If you were standing on the North Pole, you would be able to see all the circumpolar stars in the sky. Circumpolar stars are the stars that never set and orbit around the celestial pole. At the North Pole, they would constantly circle around Polaris, the North Star, without dipping below the horizon.
Why aren't circumpolar constellations visible all year long?
Circumpolar constellations are visible all year long, depending on where you are viewing them from. At the north pole, or the south pole, some constellations are visible year-round, these are the circumpolar constellations. On the equator, there are no circumpolar constellations because of the earths rotation, that is why circumpolar constellations are at the "poles". Some of the circumpolar constellations can also be viewed from other parts of the same hemisphere, such as the big dipper and the little dipper, although they are circumpolar, they are also seen in other parts of the northern hemisphere. Circumpolar constellations in the northern hemisphere, will never be seen at the south pole, and vice versa. I hope this helped.
