It is similar to longitude on the Earth, but is measured from a zero point known as the First Point of Aries. (The First Point of Aries is the point where the ecliptic meets the celestial equator in the constellation of Pisces.) It is conventionally measured in hours, minutes and seconds, rather than degrees, with one hour equal to 15 degrees.
