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.

How do you convert right ascension to degrees?
To convert right ascension to degrees, you can use the formula: 1 hour of right ascension 15 degrees. Simply multiply the number of hours of right ascension by 15 to get the equivalent in degrees.
How to convert right ascension to degrees?
To convert right ascension to degrees, you can use the formula: Degrees (RA hours / 24) x 360. Simply divide the right ascension in hours by 24, then multiply the result by 360 to get the equivalent in degrees.
How many right angles are in a full turn rotation?
A full turn rotation is equivalent to 360 degrees. Since a right angle measures 90 degrees, you can fit four right angles in a full turn rotation (360 degrees ÷ 90 degrees = 4). Therefore, there are four right angles in a full turn rotation.
How many minutes of arc are equivalent to 1 minute of right ascension?
Right ascension is expressed in units of time; one hour is equal to 15 degrees, so a minute of right ascension is equal to 1/4 degree, or 15 arc-minutes.
What is one fourth of a rotation going counterclockwise?
1/4 of 360 degrees = 90 degrees which is a right angle
What does D in a R A mean?
90 degrees in a right angle or Ninety degrees in Right Ascension = celestial coordinate.
What does 90-D in a R A mean?
90 degrees in a right angle or Ninety degrees in Right Ascension = celestial coordinate.
What does '90 D in a R A' mean?
90 degrees in a right angle or Ninety degrees in Right Ascension = celestial coordinate.
What is the right ascension and declination of constellation Capricornus?
Right ascension: 21 h Declination: −20°
What are some fascinating facts about Sagittarius?
the right ascension is 19.11h and the declination is -25.8 degrees
How are right ascension an declination similar to latitude an longitude?
Right Ascension in space is equivalent to Longitude on Earth but it is measured in hours minutes and seconds rather than degrees, minutes and seconds. 1 hour of RA is equivalent to 15° of longitude. Declination in Space is equivalent to Latitude on Earth. Both are measure in degrees, minutes and seconds. Declination is measured from the Celestial Equator, + being north and - being south, just like Latitude.
Right ascension and declination of constellation Corona Borealis?
The right ascension of Corona Borealis is approximately 16 hours, and the declination is around +30 degrees. These coordinates indicate the position of the constellation in the sky and are used by astronomers to locate it.
