How does Polaris rule support the shape of the earth?
the degree of polaris on the horizon is your latitude. Shows the curvature of the earth. When the degree of polaris is 1 degree greater, you move the some distance if you move another degree. Shows how everything is equally distant from the center.
What distance between earth and polestar?
Polaris is a Cepheid variable star 430 light years away. It has about five times the Sun's mass and has a diameter more than 40 times greater than the Sun's. Because it's an aged star fusing heavier elements for energy, it's luminosity is very high, some 2,000 times that of the Sun. That is why it shines at 2nd magnitude in our skies even though it's about the same distance from us as the Pleiades. This star is also a triple star, the distant companion being visible in small telescopes and the closer one only detectable with adaptive optics or spectroscopy
What is the luminosity of polaris?
Polaris has a luminosity of 2,200 solar luminosities.
Why is Neptune closer to Earth than Polaris?
because polaris a star
What is the absolute magnitude of POLARIS?
-3.64 is the absolute magnitude of Polaris.
How far is the polaris from earth?
The distance from earth to Polaris is estimated at 430 light years, or roughly 2,527,841,000,000,000 miles (rounded to the nearest billion miles).

How far was the north star to the earth?
The current north star, known as Polaris, has a distance estimated at 325-425 light-years. From Wikipedia: "Many recent papers calculate the distance to Polaris at about 434 light-years ... Some suggest it may be 30% closer ..."
What appears to revolve around Polaris due to earth's rotation?
Due to the vast distance between the earth and polaris, the earths axis of rotation essentially lines up with polaris at all times, so when the stars are visible, and viewed from the north pole, the earths rotation causes the stars to appear to rotate around polaris.
What is the angular separation between Polaris and Arcturus?
The declination of the star Arcturus is 19 degrees, 11 minutes, while Polaris has a declination of 89 degrees 15 minutes. Their angular separation is the distance between them, approximately 71 degrees.
What is the distance of earth to polaris?
It is estimated at approx 130 parsecs but more recent papers put it much lower: at around 100 pc.
Why is polaris so useful?
polaris useful becaused polaris forecast weather
Is a red giant a polaris?
No. Polaris is a multiple star system. In the late 18th century it was resolved into two components, Polaris A and Polaris B. Later, Polaris A was resolved further into Polaris Aa and Polaris Ab. Neither Polaris Aa nor Polaris Ab are red giants. Aa is a supergiant and Ab is a dwarf; both of them are spectral class F ("yellow-white").
Is Polaris A a Red Giant?
No. Polaris is a multiple star system. In the late 18th century it was resolved into two components, Polaris A and Polaris B. Later, Polaris A was resolved further into Polaris Aa and Polaris Ab. Neither Polaris Aa nor Polaris Ab are red giants. Aa is a supergiant and Ab is a dwarf; both of them are spectral class F ("yellow-white").

What galaxy is polaris?
