**Phoenix** is a minor [constellation](constellation "wikilink") in the
11+
[southern sky](southern_sky "wikilink"). Named after the mythical
12+
[phoenix](Phoenix_(mythology) "wikilink"), it was first depicted on a
13+
celestial atlas by [Johann Bayer](Johann_Bayer "wikilink") in his 1603
14+
*[Uranometria](Uranometria "wikilink")*. The French explorer and
15+
astronomer [Nicolas Louis de
16+
Lacaille](Nicolas_Louis_de_Lacaille "wikilink") charted the brighter
17+
stars and gave their [Bayer designations](Bayer_designation "wikilink")
18+
in 1756. The constellation stretches from roughly −39 degrees to −57 degrees
19+
[declination](declination "wikilink"), and from 23.5h to 2.5h of [right
20+
ascension](right_ascension "wikilink"). The constellations Phoenix,
21+
[Grus](Grus_(constellation) "wikilink"),
22+
[Pavo](Pavo_(constellation) "wikilink") and [Tucana](Tucana "wikilink"),
23+
are known as the Southern Birds.
24+
questions_and_answers:
25+
- question: What is the brightest star in the Phoenix constellation called?
26+
answer: >-
27+
Alpha Phoenicis or Ankaa is the brightest star in the Phoenix
28+
Constellation.
29+
- question: Where did the Phoenix constellation first appear?
30+
answer: >-
31+
The Phoenix constellation first appeared on a 35-cm diameter celestial
32+
globe published in 1597 (or 1598) in Amsterdam by Plancius with
33+
Jodocus Hondius.
34+
- question: What does 'The Bird Phoenix' symbolize?
35+
answer: '''The Bird Phoenix'' symbolizes the phoenix of classical mythology.'
36+
- context: |-
37+
Phoenix is a small constellation bordered by [Fornax](Fornax "wikilink")
38+
and Sculptor to the north, Grus to the west, Tucana to the south,
39+
touching on the corner of [Hydrus](Hydrus "wikilink") to the south, and
40+
[Eridanus](Eridanus_(constellation) "wikilink") to the east and
41+
southeast. The bright star [Achernar](Achernar "wikilink") is
42+
nearby. The three-letter abbreviation for the constellation, as
43+
adopted by the [International Astronomical
44+
Union](International_Astronomical_Union "wikilink") in 1922, is
45+
"Phe". The official constellation boundaries, as set by Belgian
46+
astronomer [Eugène Delporte](Eugène_Joseph_Delporte "wikilink") in 1930,
47+
are defined by a polygon of 10 segments. In the [equatorial coordinate
48+
system](equatorial_coordinate_system "wikilink"), the [right
49+
ascension](right_ascension "wikilink") coordinates of these borders lie
50+
between 23<sup>h</sup> 26.5<sup>m</sup> and 02<sup>h</sup> 25.0<sup>m</sup>,
51+
while the [declination](declination "wikilink")
52+
coordinates are between −39.31° and −57.84°. This means it remains
53+
below the horizon to anyone living north of the [40th
54+
parallel](40th_parallel_north "wikilink") in the [Northern
55+
Hemisphere](Northern_Hemisphere "wikilink"), and remains low in the sky
56+
for anyone living north of the [equator](equator "wikilink"). It is most
57+
visible from locations such as Australia and South Africa during late
58+
[Southern Hemisphere](Southern_Hemisphere "wikilink") spring. Most
59+
of the constellation lies within, and can be located by, forming a
60+
triangle of the bright stars Achernar, [Fomalhaut](Fomalhaut "wikilink")
61+
and [Beta Ceti](Beta_Ceti "wikilink")—Ankaa lies roughly in the centre
62+
of this.
63+
questions_and_answers:
64+
- question: What are the characteristics of the Phoenix constellation?
65+
answer: >-
66+
Phoenix is a small constellation bordered by Fornax and Sculptor to
67+
the north, Grus to the west, Tucana to the south, touching on the
68+
corner of Hydrus to the south, and Eridanus to the east and southeast.
69+
The bright star Achernar is nearby.

72+
Phoenix is most visible from locations such as Australia and South
73+
Africa during late Southern Hemisphere spring.
74+
- question: What are the Phoenix Constellation boundaries?
75+
answer: >-
76+
The official constellation boundaries for Phoenix, as set by Belgian
77+
astronomer Eugène Delporte in 1930, are defined by a polygon of 10

Ten stars have been found to have planets to date, and four planetary
81+
systems have been discovered with the [SuperWASP](SuperWASP "wikilink")
82+
project. [HD 142](HD_142 "wikilink") is a yellow giant that has an
83+
apparent magnitude of 5.7, and has a planet ([HD 142b](HD_142_b
84+
"wikilink")) 1.36 times the mass of Jupiter which orbits every 328 days.
85+
[HD 2039](HD_2039 "wikilink") is a yellow subgiant with an apparent
86+
magnitude of 9.0 around 330 light years away which has a planet ([HD 2039
87+
b](HD_2039_b "wikilink")) six times the mass of Jupiter. [WASP-18](WASP-18
88+
"wikilink") is a star of magnitude 9.29 which was discovered to have a hot
89+
Jupiter-like planet ([WASP-18b](WASP-18b "wikilink")) taking less than a
90+
day to orbit the star. The planet is suspected to be causing WASP-18 to
91+
appear older than it really is. [WASP-4](WASP-4 "wikilink") and
92+
[WASP-5](WASP-5 "wikilink") are solar-type yellow stars around 1000
93+
light years distant and of 13th magnitude, each with a single planet
94+
larger than Jupiter. [WASP-29](WASP-29 "wikilink") is an orange
95+
dwarf of spectral type K4V and visual magnitude 11.3, which has a
96+
planetary companion of similar size and mass to Saturn. The planet
97+
completes an orbit every 3.9 days.

The constellation does not lie on the
116+
[galactic plane](galactic_plane "wikilink") of the Milky Way, and there
117+
are no prominent star clusters. [NGC 625](NGC_625 "wikilink") is a dwarf
118+
[irregular galaxy](irregular_galaxy "wikilink") of apparent magnitude 11.0
119+
and lying some 12.7 million light years distant. Only 24000 light years in
120+
diameter, it is an outlying member of the [Sculptor Group](Sculptor_Group
121+
"wikilink"). NGC 625 is thought to have been involved in a collision and
122+
is experiencing a burst of [active star formation](Active_galactic_nucleus
123+
"wikilink"). [NGC 37](NGC_37 "wikilink") is a
124+
[lenticular galaxy](lenticular_galaxy "wikilink") of apparent magnitude
125+
14.66. It is approximately 42 [kiloparsecs](kiloparsecs "wikilink")
126+
(137,000 [light-years](light-years "wikilink")) in diameter and about
127+
12.9 billion years old. [Robert's Quartet](Robert's_Quartet "wikilink")
128+
(composed of the irregular galaxy [NGC 87](NGC_87 "wikilink"), and three
129+
spiral galaxies [NGC 88](NGC_88 "wikilink"), [NGC 89](NGC_89 "wikilink")
130+
and [NGC 92](NGC_92 "wikilink")) is a group of four galaxies located
131+
around 160 million light-years away which are in the process of colliding
132+
and merging. They are within a circle of radius of 1.6 arcmin,
133+
corresponding to about 75,000 light-years. Located in the galaxy ESO
134+
243-49 is [HLX-1](HLX-1 "wikilink"), an
135+
[intermediate-mass black hole](intermediate-mass_black_hole
136+
"wikilink")—the first one of its kind identified. It is thought to be a
137+
remnant of a dwarf galaxy that was absorbed in a
138+
[collision](Interacting_galaxy "wikilink") with ESO 243-49. Before its
139+
discovery, this class of black hole was only hypothesized.

Phoenix is the radiant of two annual meteor showers. The Phoenicids,
155+
also known as the December Phoenicids, were first observed on 3 December 1887.
156+
The shower was particularly intense in December 1956, and is thought related
157+
to the breakup of the short-period comet 289P/Blanpain. It peaks around 4–5
158+
December, though is not seen every year.[58] A very minor meteor shower peaks
159+
around July 14 with around one meteor an hour, though meteors can be seen
160+
anytime from July 3 to 18; this shower is referred to as the July Phoenicids.[59]
