Information about the Phoenix Constellation including the history,
characteristics, and features of the stars in the constellation.
seed_examples:
- context: |-
**Phoenix** is a minor [constellation](constellation "wikilink") in the
[southern sky](southern_sky "wikilink"). Named after the mythical
[phoenix](Phoenix_(mythology) "wikilink"), it was first depicted on a
celestial atlas by [Johann Bayer](Johann_Bayer "wikilink") in his 1603
*[Uranometria](Uranometria "wikilink")*. The French explorer and
astronomer [Nicolas Louis de
Lacaille](Nicolas_Louis_de_Lacaille "wikilink") charted the brighter
stars and gave their [Bayer designations](Bayer_designation "wikilink")
in 1756. The constellation stretches from roughly −39 degrees to −57 degrees
[declination](declination "wikilink"), and from 23.5h to 2.5h of [right
ascension](right_ascension "wikilink"). The constellations Phoenix,
[Grus](Grus_(constellation) "wikilink"),
[Pavo](Pavo_(constellation) "wikilink") and [Tucana](Tucana "wikilink"),
are known as the Southern Birds.
questions_and_answers:
- question: What is the brightest star in the Phoenix constellation called?
answer: >-
Alpha Phoenicis or Ankaa is the brightest star in the Phoenix
Constellation.
- question: Where did the Phoenix constellation first appear?
answer: >-
The Phoenix constellation first appeared on a 35-cm diameter celestial
globe published in 1597 (or 1598) in Amsterdam by Plancius with
Jodocus Hondius.
- question: What does 'The Bird Phoenix' symbolize?
answer: '''The Bird Phoenix'' symbolizes the phoenix of classical mythology.'
- context: |-
Phoenix is a small constellation bordered by [Fornax](Fornax "wikilink")
and Sculptor to the north, Grus to the west, Tucana to the south,
touching on the corner of [Hydrus](Hydrus "wikilink") to the south, and
[Eridanus](Eridanus_(constellation) "wikilink") to the east and
southeast. The bright star [Achernar](Achernar "wikilink") is
nearby. The three-letter abbreviation for the constellation, as
adopted by the [International Astronomical
Union](International_Astronomical_Union "wikilink") in 1922, is
"Phe". The official constellation boundaries, as set by Belgian
astronomer [Eugène Delporte](Eugène_Joseph_Delporte "wikilink") in 1930,
are defined by a polygon of 10 segments. In the [equatorial coordinate
system](equatorial_coordinate_system "wikilink"), the [right
ascension](right_ascension "wikilink") coordinates of these borders lie
between 23<sup>h</sup> 26.5<sup>m</sup> and 02<sup>h</sup> 25.0<sup>m</sup>,
while the [declination](declination "wikilink")
coordinates are between −39.31° and −57.84°. This means it remains
below the horizon to anyone living north of the [40th
parallel](40th_parallel_north "wikilink") in the [Northern
Hemisphere](Northern_Hemisphere "wikilink"), and remains low in the sky
for anyone living north of the [equator](equator "wikilink"). It is most
visible from locations such as Australia and South Africa during late
[Southern Hemisphere](Southern_Hemisphere "wikilink") spring. Most
of the constellation lies within, and can be located by, forming a
triangle of the bright stars Achernar, [Fomalhaut](Fomalhaut "wikilink")
and [Beta Ceti](Beta_Ceti "wikilink")—Ankaa lies roughly in the centre
of this.
questions_and_answers:
- question: What are the characteristics of the Phoenix constellation?
answer: >-
Phoenix is a small constellation bordered by Fornax and Sculptor to
the north, Grus to the west, Tucana to the south, touching on the
corner of Hydrus to the south, and Eridanus to the east and southeast.
The bright star Achernar is nearby.
- question: When is the phoenix constellation most visible?
answer: >-
Phoenix is most visible from locations such as Australia and South
Africa during late Southern Hemisphere spring.
- question: What are the Phoenix Constellation boundaries?
answer: >-
The official constellation boundaries for Phoenix, as set by Belgian
astronomer Eugène Delporte in 1930, are defined by a polygon of 10
segments.
- context: |-
Ten stars have been found to have planets to date, and four planetary
systems have been discovered with the [SuperWASP](SuperWASP "wikilink")
project. [HD 142](HD_142 "wikilink") is a yellow giant that has an
apparent magnitude of 5.7, and has a planet ([HD 142b](HD_142_b
"wikilink")) 1.36 times the mass of Jupiter which orbits every 328 days.
[HD 2039](HD_2039 "wikilink") is a yellow subgiant with an apparent
magnitude of 9.0 around 330 light years away which has a planet ([HD 2039
b](HD_2039_b "wikilink")) six times the mass of Jupiter. [WASP-18](WASP-18
"wikilink") is a star of magnitude 9.29 which was discovered to have a hot
Jupiter-like planet ([WASP-18b](WASP-18b "wikilink")) taking less than a
day to orbit the star. The planet is suspected to be causing WASP-18 to
appear older than it really is. [WASP-4](WASP-4 "wikilink") and
[WASP-5](WASP-5 "wikilink") are solar-type yellow stars around 1000
light years distant and of 13th magnitude, each with a single planet
larger than Jupiter. [WASP-29](WASP-29 "wikilink") is an orange
dwarf of spectral type K4V and visual magnitude 11.3, which has a
planetary companion of similar size and mass to Saturn. The planet
completes an orbit every 3.9 days.

answer: >-
In the Phoenix constellation, ten stars have been found to have
planets to date, and four planetary systems have been discovered with
the SuperWASP project.
- question: What is HD 142?
answer: >-
HD 142 is a yellow giant that has an apparent magnitude of 5.7, and

- question: Are WASP-4 and WASP-5 solar-type yellow stars?
answer: >-

years distant and of 13th magnitude, each with a single planet larger
than Jupiter.
- context: |-
The constellation does not lie on the
[galactic plane](galactic_plane "wikilink") of the Milky Way, and there
are no prominent star clusters. [NGC 625](NGC_625 "wikilink") is a dwarf
[irregular galaxy](irregular_galaxy "wikilink") of apparent magnitude 11.0
and lying some 12.7 million light years distant. Only 24000 light years in
diameter, it is an outlying member of the [Sculptor Group](Sculptor_Group
"wikilink"). NGC 625 is thought to have been involved in a collision and
is experiencing a burst of [active star formation](Active_galactic_nucleus
"wikilink"). [NGC 37](NGC_37 "wikilink") is a
[lenticular galaxy](lenticular_galaxy "wikilink") of apparent magnitude
14.66. It is approximately 42 [kiloparsecs](kiloparsecs "wikilink")
(137,000 [light-years](light-years "wikilink")) in diameter and about
12.9 billion years old. [Robert's Quartet](Robert's_Quartet "wikilink")
(composed of the irregular galaxy [NGC 87](NGC_87 "wikilink"), and three
spiral galaxies [NGC 88](NGC_88 "wikilink"), [NGC 89](NGC_89 "wikilink")
and [NGC 92](NGC_92 "wikilink")) is a group of four galaxies located
around 160 million light-years away which are in the process of colliding
and merging. They are within a circle of radius of 1.6 arcmin,
corresponding to about 75,000 light-years. Located in the galaxy ESO
243-49 is [HLX-1](HLX-1 "wikilink"), an
[intermediate-mass black hole](intermediate-mass_black_hole
"wikilink")—the first one of its kind identified. It is thought to be a
remnant of a dwarf galaxy that was absorbed in a
[collision](Interacting_galaxy "wikilink") with ESO 243-49. Before its
discovery, this class of black hole was only hypothesized.
questions_and_answers:
- question: Is the Phoenix Constellation part of the Milky Way?
answer: >-
The Phoenix constellation does not lie on the galactic plane of the
Milky Way, and there are no prominent star clusters.
- question: How many light years away is NGC 625?
answer: >-
NGC 625 is 24000 light years in diameter and is an outlying member of
the Sculptor Group.
- question: What is Robert's Quartet composed of?
answer: >-
Robert's Quartet is composed of the irregular galaxy NGC 87, and three
spiral galaxies NGC 88, NGC 89 and NGC 92.
- context: |-
Phoenix is the radiant of two annual meteor showers. The Phoenicids,
also known as the December Phoenicids, were first observed on 3 December 1887.
The shower was particularly intense in December 1956, and is thought related
to the breakup of the short-period comet 289P/Blanpain. It peaks around 4–5
December, though is not seen every year.[58] A very minor meteor shower peaks
around July 14 with around one meteor an hour, though meteors can be seen
anytime from July 3 to 18; this shower is referred to as the July Phoenicids.[59]
questions_and_answers:
- question: Do meteor showers originate from the Pheonix constellation?
answer: Phoenix is the radiant of two annual meteor showers.
- question: When were the first Phoenicids?
answer: >-
The Phoenicids, also known as the December Phoenicids, were first
observed on 3 December 1887.
- question: When does the intensity of the Phoenicids peak?
answer: It peaks around 4–5 December, though is not seen every year.
