Technically, every single one of them - but the ones that are closest are Ursa Major, Cassiopeia, Ursa Minor, Cepheus, & Draco.
These are called circumpolar constellations.
Also known as the North Star, Polaris, is located within one degree of the north celestial pole - the point of Earth's axis of rotation. This means that the Earth's (geographic) north pole is pointing almost exactly to the point in the sky where Polaris is located. For this reason, Polaris can be seen by anyone in the northern hemisphere throughout the year.
Circumpolar constellations are star patterns that are always visible in the night sky from a specific location on Earth, as they appear to circle around the celestial pole without ever setting below the horizon. These constellations are visible all year round in the northern or southern hemisphere, depending on your location. Examples of circumpolar constellations in the northern hemisphere include Ursa Major and Cassiopeia.
To find circumpolar constellations, look towards the north if you are in the Northern Hemisphere or towards the south if you are in the Southern Hemisphere. Circumpolar constellations are visible all year round and appear to "circle" around the celestial poles without setting below the horizon.
All the constellations were fixed to a crystal sphere that rotates at a slightly different rate from the Sun's rotation rate. So while the Sun goes round 365 times in a year, the sphere of the constellations go round 366 times.
Three constellations that can be seen year-round from the northern hemisphere are Ursa Major (which includes the Big Dipper), Orion, and Cassiopeia. These constellations are visible at different times of the year and at varying positions in the sky.
Seasonal constellations are visible only at certain times of the year due to Earth's orbit around the Sun, while circumpolar constellations are visible year-round from a specific location near the poles due to their proximity to the celestial pole. Seasonal constellations rise and set, while circumpolar constellations appear to constantly circle the celestial pole without rising or setting.
You should use Polaris ps-4 synthetic oil for year round use. l
It is both, as Cassiopeia is one of the constellations that can be seen all year round.
Some of the constellations visible all year long from the northern hemisphere include Ursa Major (containing the Big Dipper), Ursa Minor (containing the Little Dipper with Polaris, the North Star), and Cassiopeia. In the southern hemisphere, constellations like Centaurus and Crux (Southern Cross) remain visible throughout the 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.
