Right Ascension is the 'longitude' of celestial objects. The celestial 'Prime Meridian' ... the position
defined as zero RA is the celestial meridian that passes through the Vernal Equinox, and the Right
Ascension of every point in the sky is measured westward from there. It's expressed in terms of
hours, minutes, and decimal seconds, where 1 hour corresponds to 15 degrees of angle. Notice
that unlike terrestrial longitude, Right Ascension isn't measured in both directions from the zero
meridian. There's no east or west Right Ascension, only one number, that ranges from zero through
24 hours.
What else can I help you with?
Is right ascension measured in hours minutes and seconds?
Yes, right ascension is typically measured in hours, minutes, and seconds. It is one of the coordinates used in the equatorial coordinate system to locate objects in the sky.
Are latitude and right ascension are coordinate systems used to find objects on the celestial sphere?
Yes, latitude and right ascension are both coordinate systems used for locating objects on the celestial sphere. Latitude is measured in degrees north or south of the celestial equator, while right ascension is measured in hours, minutes, and seconds eastward from the vernal equinox. Right ascension is analogous to longitude on Earth.
Where does the clock start for right ascension?
The "zero" or reference for right ascension in the sky is the meridian that joins the north and south poles of the sky and passes through the vernal equinox ... that's the point where the sun crosses the celestial equator moving north, on March 21.
Is mercury in the right ascension?
"Right ascension" is just one number for the coordinates of a planet, star, etc. Any such object has a right ascension.
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.
Is right ascension measured in hours minutes and seconds?
Yes, right ascension is typically measured in hours, minutes, and seconds. It is one of the coordinates used in the equatorial coordinate system to locate objects in the sky.

How do you spell ascension?
Ascension, you spelt it right.
What does Right Ascension mean?
Right ascension is essentially the longitude on a star chart where you may look to find something in the sky among the stars. The distance of a point east of the First Point of Aries, measured along the celestial equator and expressed in hours, minutes, and seconds.
Is mercury in the right ascension?
"Right ascension" is just one number for the coordinates of a planet, star, etc. Any such object has a right ascension.
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.
What is the ascension of Pisces?
The Right ascension of Pisces is 1.
What is the right ascension and declination of Microscopium?
Right ascension is 21 h and declination is −36°.
What is the right ascension of Crater constellation?
Constellation Crater's right ascension is 11 h
What is the right ascension and declination of Canis Minor?
Right ascension: 8 h Declination: +5°
What is the right ascension and declination of the Leo constellation?
Right ascension: 11 h Declination: +15°
