Is the North Star True North?
The beauty of using the north star for navigation is that unlike a magnetic compass the north star always points to to true north. This means that when you are observing this star you are facing true north toward the North Pole. Because of this we also call the North Star the Polestar or Polaris, its astronomic name.
How accurate is the North Star?
If you took its picture, you’d find that it makes its own little circle around the exact point of the north celestial pole every day. That’s because the North Star is really offset a little – by about three-quarters of a degree – from celestial north.
Why is the North Star so special?
What is the North Star? The reason Polaris is so important is because the axis of Earth is pointed almost directly at it. So at any hour of the night, at any time of the year in the Northern Hemisphere, you can readily find Polaris and it is always found in a due northerly direction.

Tabby’s Star (also known as Boyajian’s Star and WTF Star, and designated KIC 8462852 in the Kepler Input Catalog) is an F-type main-sequence star in the constellation Cygnus approximately 1,470 light-years (450 pc) from Earth.
How hot is the hottest star in the universe?
Eta Carinae could be as large as 180 times the radius of the Sun, and its surface temperature is 36,000-40,000 Kelvin. Just for comparison, 40,000 Kelvin is about 72,000 degrees F. So it’s the blue hypergiants, like Eta Carinae, which are probably the hottest stars in the Universe.
