The stars in the Big Dipper and Little Dipper help navigators locate the North Star. Following the five stars in the Five Star Trail—the municipalities of Hempfield Township, Youngwood, South Greensburg, Southwest Greensburg, and Greensburg—takes travelers on a more northeastern tack. All five towns in the constellation partnered to create the nearly 7.8-mile trail southeast of Pittsburgh.
Following the concept of the Five Star trail these caches will be named for different constellations.
Apus constellation is located in the southern hemisphere. It is a small constellation that represents the bird of paradise. The name of the constellation is derived from the Greek word apous, which means “footless.” (Birds of paradise were at one point in history believed to lack feet.) There are no myths associated with the constellation.
Apus was created by the Dutch astronomer and cartographer Petrus Plancius from the observations of Dutch navigators Pieter Dirkszoon Keyser and Frederick Houtman, and first catalogued by Plancius in the late 16th century.
Apus is home to two notable deep sky objects: the globular clusters NGC 6101 and IC 4499. The constellation also contains the galaxies IC 4633 and IC 4635.
