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.
The right ascension of a celestial body is measured from the vernal equinox point in the sky, which is where the Sun crosses the celestial equator from south to north each year. It is measured in hours, minutes, and seconds along the celestial equator eastward from the vernal equinox.
Units of time: hours, minutes and seconds, to make it correspond to the rotation of the Earth (the sky thus rotates approximately by a right asencion of "1 hour" during a time of one hour).

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 clock for right ascension starts at the vernal equinox, which is the point in space where the celestial equator intersects the ecliptic. This point is used as the zero point from which right ascension is measured in the sky.
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.

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 clock for right ascension starts at the vernal equinox, which is the point in space where the celestial equator intersects the ecliptic. This point is used as the zero point from which right ascension is measured in the sky.
How do you spell ascension?
Ascension, you spelt it right.
What does Right Ascension mean?
Right Ascension is a celestial coordinate that measures the eastward angular distance of a celestial object from the vernal equinox, along the celestial equator. It is similar to longitude on Earth but is used in astronomy to pinpoint the position of stars and other celestial objects in the sky. Right Ascension is typically measured 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.
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°
What is the range of values for right ascension?
Right ascension is measured in hours, minutes, and seconds, with a range from 0 hours to 24 hours. This corresponds to a full circle around the celestial sphere. Each hour is divided into 60 minutes and each minute into 60 seconds.
