What is the range of values for declination?
+90 to -90 degrees
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 declination of polaris from Glasgow?
The "declination" of a star is its position in the sky on the celestial sphere, which stays the same for any observer.You may be thinking about how high Polaris is above the horizon.That's its "altitude".The altitude of Polaris always equals the latitude of the observer.That's been a great help to seafarers for centuries.Polaris has a declination of nearly 90 degrees.From Glasgow, its altitude in the northern sky is equal to the latitude of Glasgow.The latitude of Glasgow is about 55.9 degrees.So, the altitude of Polaris in Glasgow is about 55.9 degrees.
What are the coordinates of the star Polaris?
In the celestial coordinate system Polaris is located at the following coordinates: Right Ascension: 02 Hours 48.2 Minutes (measured from 0-24 Hour format) Declination: +89 Degrees 19 Minutes (measured from +90 to -90 Degree format)
Is Polaris almost at plus 90 degrees?
Yes, Polaris is about 89 and 1/4 degrees
What is the altitude of polaris above the northern horizon for observer a?
90 degrees
One hour of right ascension is equivalent to how many degrees of sky rotation?
Depends on the declination in question. There are 24 hours of right ascension in 360 degrees, so at the celestial equator (declination = 0 degrees) 1 hour of right ascension is equal to 15 degrees. But as you increase or decrease declination the right ascension lines converge to the celestial pole (like longitude lines on a globe). The angle covered by 1 hour of right ascension is therefore equal to (15 degrees x cos(declination) ), so at the celestial poles (declination = +/- 90 degrees) 1 hour of RA is 0 degrees.
Is The south celestial pole is located at a declination of -90 degrees?
The Celestial Poles are the infinite extension of the North and South Poles from the Earth into space. The North Star or Polaris, is within 1 degree of the North Celestial Pole. There is no equivalent star for the South Celestial Pole.
What is the range of values that the coordinate declination can have?
-90° to +90°
What location will the highest altitude of the star Polaris be observed?
If you are at the North Pole, you'll see the star Polaris near the zenit (altitude almost 90 degrees).
Declination of constellation Corvus?
Corvus the Crow is centered roughly on -20 degrees in Declination.
How the condition of a celestial body to be a circumpolar body?
it is circumpolar if the body has a declination greater than the co-latitude, that is 90 degrees minus the latitude of the observer
