The full constellation occupies a large range of right ascensions.
The main stars in Gemini are:
Castor: R.A. = 7hr 35min 12sec
Pollux: R.A. = 7hr 45min 54sec
Right now (middle of September 2009), Mars happens to be right near Pollux. Don't miss it.
"Right ascension" is just one number for the coordinates of a planet, star, etc. Any such object has a right ascension.
No.
0-24 hours
According to Wikipedia: Right ascension 04h 35m 55.239s, declination +16° 30′ 33.49″. The data corresponds to the epoch 2000.0.
Using declination and right ascension
Ascension, you spelt it right.
"Right ascension" is just one number for the coordinates of a planet, star, etc. Any such object has a right ascension.
The right ascension of Leo is 11 h
The Right ascension of Pisces is 1.
Right ascension is 21 h and declination is −36°.
Constellation Crater's right ascension is 11 h
Right ascension: 8 h Declination: +5°
Right ascension: 21 h Declination: −20°
Right ascension: 11 h Declination: +15°
Right ascension: 16 h Declination: +30°
yes. latitude is to declination, as longitude is to right ascension.
The Right ascension is 07h 55m 19.7973s-09h 22m 35.0364s and the Declination is 33.1415138°-6.4700689°.
