What does the Southern Cross stand for?

The abbreviation Cru symbolizes right ascension 12 h right ascension -60.

Rank: Number of bright stars in the 88th place (magnitude)

The main bright stars in the Southern Cross meteor shower constellation: Cross I (γ), Cross II (α), Cross III (β) and Cross IV (δ) form a cross. Because there are no bright stars near the south celestial pole, cross I and cross II are used to indicate the direction-only by extending the distance between them by about 4.5 times is the south celestial pole. So this cross is as important in the southern hemisphere as Beidou in the northern hemisphere.

In addition, the intersection of the middle vertical line connecting Nanmenxing Centauri and Marbury I and the above extension line will also be the south celestial pole.

The coal pocket nebula located in the Milky Way is one of the most striking dark nebulae in the sky, which can be easily seen with the naked eye.

NGC4755, discovered in 175 1 and 52, is another deep-space object of the Southern Cross. Commonly known as "jewelry box",

It is about 7500 light years away from the Earth and contains about 100 stars. Australia, New Zealand, Brazil, Papua New Guinea and Samoa all have the Southern Cross on their flags.
