Constellation Guide

Constellation guide to the 88 official constellations which divide up the sky. These constellations are used to help navigate the celestial sphere. The Constellations are patterns in the sky which have been to invented and have deep mythology behind them. Constellations cover massive areas in the sky and as such are very easy to find.

Some of the constellations have very familiar names, such as Leo, Gemini, Virgo and Aquarius. There are 12 of these constellations and they form the Zodiac. The Zodiac constellations follow the line of the ecliptic. The ecliptic is the apparent path of the Sun on the celestial sphere.

Delphinus

The Dolphin

Delphinus is a rather small northern constellation very close to the celestial equator. It was already included in Ptolemy's list of 48 constellations and also forms part of the modern list of 88 constellations approved by the IAU.

Delphinus Mythology

According to the first one, Greek god Poseidon wanted to marry Amphitrite, a nereid. She, however, wanting to protect her virginity, fled to the Atlas mountains. Her suitor then sent out several searchers, among them a certain Delphinus. Delphinus accidentally stumbled upon her and was able to persuade Amphitrite to accept Poseidon's wooing. Out of gratitude the god placed the image of a dolphin among the stars.

Further Information

It looks remarkably like a leaping dolphin and thus can easily be recognized in the sky. Delphinus is surrounded (clockwise from north) by the little fox Vulpecula, the flying arrow Sagitta, the eagle Aquila, the water carrier Aquarius, the little horse Equuleus and finally the flying horse Pegasus.
