Welcome to featured Wiki of the Day where we read the summary of the featured Wikipedia article every day.
The featured article for Sunday, 23 July 2023 is Pavo (constellation).
Pavo is a constellation in the southern sky whose name is Latin for "peacock". Pavo first appeared on a 35-cm (14 in) diameter celestial globe published in 1598 in Amsterdam by Plancius and Jodocus Hondius and was depicted in Johann Bayer's star atlas Uranometria of 1603, and was likely conceived by Petrus Plancius from the observations of Pieter Dirkszoon Keyser and Frederick de Houtman. French explorer and astronomer Nicolas-Louis de Lacaille gave its stars Bayer designations in 1756. The constellations Pavo, Grus, Phoenix and Tucana are collectively known as the "Southern Birds".
The constellation's brightest member, Alpha Pavonis, is also known as Peacock and appears as a 1.91-magnitude blue-white star, but is actually a spectroscopic binary. Delta Pavonis is a nearby Sun-like star some 19.9 light-years distant. Six of the star systems in Pavo have been found to host planets, including HD 181433 with a super-Earth, and HD 172555 with evidence of a major interplanetary collision in the past few thousand years. The constellation contains NGC 6752, the fourth-brightest globular cluster in the sky, and the spiral galaxy NGC 6744, which closely resembles the Milky Way but is twice as large. Pavo displays an annual meteor shower known as the Delta Pavonids, whose radiant is near the star δ Pav.
