Constellation Triangulum (The Triangle)

Triangulum or The Triangle is one of the 88 constellations modern astronomers have divided the sky into. It's part of the Perseus constellation family. Triangulum is best seen in December (from latitudes +90° to -50°)

This constellation is located between Andromeda, Perseus, and Aries. Aratus described it as an isosceles triangle, having two equal sides and a shorter third side. Eratosthenes said that it represented the Nile river delta. Roman stargazers, on the other hand, associated it with the island of Sicily, which is somewhat triangular in shape. As of 2016, Triangulum has 4 recognized planets.
