⭐ Core Definition: Crux

Crux (/krʌks/ KRUKS) is a constellation of the southern sky that is centred on four bright stars in a cross-shaped asterism commonly known as the Southern Cross. It lies on the southern end of the Milky Way's visible band. The name Crux is Latin for cross. Though it is the smallest of all 88 modern constellations, Crux is among the most easily distinguished, as each of its four main stars has an apparent visual magnitude brighter than +2.8. It has attained a high level of cultural significance in many Southern Hemisphere states and nations.

Blue-white α Crucis (Acrux) is the most southerly member of the constellation, and at magnitude 0.8, the brightest. The three other stars of the cross appear clockwise and in order of lessening magnitude: β Crucis (Mimosa), γ Crucis (Gacrux), and δ Crucis (Imai). ε Crucis (Ginan) also lies within the cross asterism. 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.

Crux in the context of Constellation of Andromeda

Andromeda is one of the 48 constellations listed by the 2nd-century Greco-Roman astronomer Ptolemy, and one of the 88 modern constellations. Located in the northern celestial hemisphere, it is named for Andromeda, daughter of Cassiopeia, in the Greek myth, who was chained to a rock to be eaten by the sea monster Cetus. Andromeda is most prominent during autumn evenings in the Northern Hemisphere, along with several other constellations named for characters in the Perseus myth. Because of its northern declination, Andromeda is visible only north of 40° south latitude; for observers farther south, it always lies below the horizon. It is one of the largest constellations, with an area of 722 square degrees. This is over 1,400 times the size of the full moon, 55% of the size of the largest constellation, Hydra, and over 10 times the size of the smallest constellation, Crux.

Its brightest star, Alpheratz (Alpha Andromedae), is a binary star that has also been counted as a part of Pegasus, while Gamma Andromedae (Almach) is a colorful binary and a popular target for amateur astronomers. With a variable brightness similar to Alpheratz, Mirach (Beta Andromedae) is a red giant, its color visible to the naked eye. The constellation's most obvious deep-sky object is the naked-eye Andromeda Galaxy (M31, also called the Great Galaxy of Andromeda), the closest spiral galaxy to the Milky Way and one of the brightest Messier objects. Several fainter galaxies, including M31's companions M110 and M32, as well as the more distant NGC 891, lie within Andromeda. The Blue Snowball Nebula, a planetary nebula, is visible in a telescope as a blue circular object.

Crux in the context of Hateruma

Hateruma (波照間島; Yaeyama: Patirooma, Hateruma dialect: Besїma "our island", Okinawan: Hatiruma, Northern Ryukyuan: ぱたら Patara, Japanese:Hateruma-jima) is an island in the Yaeyama District of Okinawa Prefecture, Japan. It is the southernmost inhabited island in Japan. It is one of the Yaeyama Islands, and is located 24 kilometres (15 mi) south of Iriomote-jima, the largest of the island group.

Hateruma, which is composed of corals, has 12.7 km (4.9 sq mi) of area and approximately 600 inhabitants. The primary products of the island include sugarcane, pineapple, refined sugar, and Awanami, a type of the alcoholic beverage awamori. Its southern location makes it one of the few places in Japan where the Southern Cross can be observed.

Crux in the context of Equuleus

Equuleus is a faint constellation located just north of the celestial equator. Its name is Latin for "little horse", a foal. It was one of the 48 constellations listed by the 2nd century astronomer Ptolemy, and remains one of the 88 modern constellations. It is the second smallest of the modern constellations (after Crux), spanning only 72 square degrees. It is also very faint, having no stars brighter than the fourth magnitude.

Crux in the context of Defacement (flag)

In vexillology, defacement is the addition of a symbol or charge to a flag. For example, the Australian flag is the British Blue Ensign defaced with a Southern Cross in the fly.

In the context of vexillology, the word "deface" carries no negative connotations, in contrast to general usage. It simply indicates a differentiation of the flag from that of another owner by addition of elements. For example, many state flags are formed by defacing the national flag with a coat of arms.
