...constellation Aries. It is currently in the constellation Pisces and is moving in the direction of the constellation Aquarius. The first point of Aries is the prime meridian for right ascension. By definition, its coordinates are always 0 degrees R.A., 0 degrees declination . This means that astronomical coordinates should, to be accurate, refer to the date when the measurements were taken.

.... Question for students: Under what conditions would you think absolute zero might actually exist in the universe? 1 An example of extrapolation would be: If we know that the brightness of a a light is x lumens when measured at a distance of 1 meter, and that it is x /4 lumens at 2 meters, we can extrapolate the brightness at, for example, 3.6 meters, 7,258,491.682 meters, or 0.0052 meter.
