Crux

Crux /ˈkrʌks/ is a constellation located in the southern sky in a bright portion of the Milky Way, and is the smallest but one of the most distinctive of the 88 modern constellations. Its name is Latin for cross, and it is dominated by a cross-shaped or kite-like asterism that is commonly known as the Southern Cross.

Predominating the asterism is the most southerly first-magnitude star and brightest star in the constellation, the blue-white Alpha Crucis or Acrux, followed by four other stars, descending in clockwise order by magnitude: Beta, Gamma (one of the closest red giants to Earth), Delta and Epsilon Crucis. Many of these brighter stars are members of the Scorpius–Centaurus Association, a large but loose group of hot blue-white stars that appear to share common origins and motion across the southern Milky Way. The constellation contains four Cepheid variables that are visible to the naked eye under optimum conditions. Crux also contains the bright and colourful open cluster known Jewel Box (NGC 4755) and, to the southwest, partly includes the extensive dark nebula, known as the Coalsack Nebula.

Crux (Chinese astronomy)

The modern constellation Crux is not included in the Three Enclosures and Twenty-Eight Mansions system of traditional Chinese uranography because its stars are too far south for observers in China to know about them prior to the introduction of Western star charts. Based on the work of Xu Guangqi and the German Jesuit missionary Johann Adam Schall von Bell in the late Ming Dynasty, this constellation has been classified as one of the 23 Southern Asterisms (近南極星區, Jìnnánjíxīngōu) under the name Cross (十字架, Shízìjià).

Possibly Acrux (Alpha Crucis), Mimosa (Beta Crucis) and Gacrux (Gamma Crucis) are bright stars in this constellation that never seen in Chinese sky.

The name of the western constellation in modern Chinese is 南十字座 (nán shí zì zuò), meaning "the southern cross-shaped constellation".

Crux (climbing)

A crux in climbing, mountaineering and high mountain touring is the most difficult section of a route, or the place where the greatest danger exists. In sport climbing and bouldering the most challenging point is also called the crux. In describing a climbing route using a topo, cruces (or cruxes) are usually shown with a key symbol.

The grade of a climbing route is based on the difficulty of the crux. That means the rest of the route can be considerably easier. In addition a route may comprise several cruces. There are also routes, however, that have a very consistent level of difficulty with no sections that stand out as harder than the rest.

In planning a route it is important to know how far it is before the crux is reached, because cruces can only be overcome with sufficient reserves of strength.
