Where on Earth can you see all the stars over a year?
At the Earth’s equator, no star is circumpolar because all the stars rise and set daily in that part of the world. You can (theoretically) see every star in the night sky over the course of one year. In practice, of course, things like clouds and horizon haze get in the way.
What degree is Polaris?
Remember that the altitude of Polaris is 0 degrees if you are observing from the equator (0 degrees latitude) and 90 degrees if you are observing from the north pole (latitude 90 degrees), and it is also true for intermediate latitudes. So, knowing the altitude of Polaris lets you know your latitude on Earth.
What is the brightest star you can see from Earth?
Sirius, also known as the Dog Star or Sirius A, is the brightest star in Earth’s night sky. The name means “glowing” in Greek — a fitting description, as only a few planets, the full moon and the International Space Station outshine this star.

Why does Polaris not move?
Polaris is the star in the center of the star field; it shows essentially no movement. Earth’s axis points almost directly to Polaris, so this star is observed to show the least movement. The other stars appear to trace arcs of movement because of Earth’s spin on its axis.
What was Earth’s northern star before Polaris?
The Northern Hemisphere also has had long stretches without a pole star. After the reign of Thuban but before that of Polaris, Kochab in the Little Dipper served as a rather poor pole star in 1100 B.C. Kochab was only half again as close to the north celestial pole as it is today.
