The History Of Crux Constellation

The Crux constellation, also famously known as the Southern Cross, is one of the most recognizable constellations in the southern sky. It spans an area of 68 square degrees and is best viewed between +20° and -90° latitude. It is located in the third quadrant of the southern hemisphere (SQ3).

The constellation was first recorded by European navigators in the 16th century.

Dutch astronomer Petrus Plancius was among the early cartographers who mapped out Crux.

Because of its distinctive cross shape, it quickly became a navigational aid for sailors traveling the southern seas.

Crux is nestled among other significant constellations.

To its east, you’ll find Centaurus, and to its south, the small constellation of Musca. This makes Crux part of the Hercules family of constellations.

Important objects within Crux include the Coalsack Nebula and the Jewel Box Cluster.

The Coalsack Nebula is a famous dark nebula easily spotted with the naked eye, while the Jewel Box Cluster, also known as NGC 4755, is a vibrant open cluster of stars.

The name “Crux” comes from the Latin word for “cross,” reflecting its shape.

It’s also been a prominent symbol in various cultures and features on the national flags of several countries in the southern hemisphere.

Viewing from Different Locations

To view Crux from the southern hemisphere, look towards the southern horizon. The constellation is easily visible without any equipment.

If you are in the northern hemisphere, you need to be in the southernmost regions, such as southern Florida or Texas, around 26 degrees north latitude or further south.

You may have limited visibility due to its proximity to the horizon.

Locate Crux by first finding the south celestial pole, then looking nearby for the cross-shaped pattern. Crux is often used for navigation, as its stars point towards the south celestial pole.
