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 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 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.
In star language what does RA stand for?
Right Ascension. It's the celestial equivalent of longitude.
How many degrees in a circle would be equal to one hour of right ascension?
it would be 30 degrees It is 15 degrees. (360 degrees/24 hours = 15).
In a right angle how many degrees is one third of a quarter of a rotation?
A right angle is 90 degrees, so one third of a right angle is 30 degrees.
What is a four right angle turns?
A complete rotation of 360 degrees
How do you spell ascension?
Ascension, you spelt it right.
