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.
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.
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.
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.
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.
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.
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: 11 h Declination: +15°
yes. latitude is to declination, as longitude is to right ascension.
The right ascension of Leo is 11 h
Right ascension: 21 h Declination: −20°
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.
