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 constellations are visible all year long?

Depends where you live....


What Constellations are visible all year?

The constellations near the plane of the ecliptic (the zodiacal constellations) are only visible at certain times of the year. The constellations towards the poles (N and S) are visible at all times of the year from their respective hemispheres. In the South, the Southern Cross would be one example and in the North the Great Bear (or plough) would be another.

Why are certain constellations put on the circumpolar constellation chart and other are on the equatorial constellation chart?

because the circumpolar constellations are visible all year long and the others are not.


Are all constellations visible all the time?

No. As we orbit the Sun different constellations become visible, but we can only see them when it is dark. Constellations are in the sky during daylight, but the Sun is so bright, we cannot see them. A few months after that, they start to be visible in the evenings and soon at night, by which time other constellations are in daylight and cannot be seen. You will see any constellation at the same time of year, every year. So the constellations you see in the night sky tonight are the same as the ones you will see on this date in any other year. The only thing that will differ is where the Moon and planets are.


How does earth revolution affect the viewing of constellation?

As earth orbits the sun, different constellations come into view while others disappear. Circumpolar constellations are visible all year long, other constellations are not.


What constellations would you see in the northern hemisphere?

Half of all constellations are visible from the north pole, andall of them are visible from one inch north of the equator.


What constellations are visible from Earth?

All of them are. The constellations were all invented by human beings, on Earth. None were invented that can't be seen from Earth.


Famous Constellations near Draco?

Draco is just west (higher longitude) of Ursa Major and Ursa Minor. All three are "circumpolar" constellations visible for most of the year in the Northern Hemisphere.

What are the only constellations visible all year long?

The region of the sky visible all year round is called "circumpolar". What stars and constellations are included there depends on your geographical location. For example, for somebody living 30 degrees south of the equator, a region around the south pole of the sky, with a radius of 30 degrees, would be circumpolar.


What constellations are visible to earth during all 12 months of the year these are the circumpolar constellations?

There are dozens, but it would depend on where you live. For example, if you live in the Arctic or Antarctic, you can't see ANY stars at midsummer, when the Sun is up all the time.
