Conjunction
(glossary entry)Description
A Conjunction occurs when the Sun and Moon are at the same ecliptic longitude (rotation angle measured in the plane of the solar system bodies). This means that they are close together in the sky, but not necessarily overlapping, since they may differ in latitude (the coordinate perpendicular to the ecliptic longitude). - Jim Mosher
Additional Information
- The moment of New Moon is defined as the moment when the Sun and Moon are in conjunction as seen by an imaginary observer at the Earth's center. - Jim Mosher
Saber's Beads
- Saber's Beads is (or: are) a curious optical phenomenon related to the very young (and extremely thin) moon's crescent (only a couple of hours after New Moon). Saber's Beads are also observable at the very OLD moon's crescent, a couple of hours before New Moon. - DannyCaes Feb 12, 2008
Celestial Smiley
- Imagine a triangle-shaped conjunction of the Waxing Crescent Moon, Venus, and Jupiter (the most brightest celestial objects). The moon's crescent acting like a smiling mouth, and the two planets acting like staring eyes. Something like this must have been observed somewhere in the past. Perhaps more than once. A good digital planetarium-program could show such an appearance, with calendar date, and hour. - DannyCaes Dec 4, 2016
