The former is quite prominent; the latter has only two planets and has a host star farther away at 21.5 parsecs. [8] Originally discovered by Chinese astronomers in 401, Eta Aquariids can be seen coming from the Water Jar beginning on 21 April and as late as 12 May. Aquarius is also associated with the Age of Aquarius, a concept popular in 1960s counterculture. The boundary of the Aquarius constellation contains 17 stars that host known exoplanets. In Babylonian mythology, Aquarius was associated with the god Ea. The Eta Aquariids are the strongest meteor shower radiating from Aquarius.

Sea and Sky receives commissions for purchases made through links on this site. The two brightest stars, Alpha and Beta Aquarii, are luminous yellow supergiants, of spectral types G0Ib and G2Ib respectively,[10] that were once hot blue-white B-class main sequence stars 5 to 9 times as massive as the Sun. Naked-eye = 5 (suburbs) However, because it is so large, it is only viewable as a very faint object,[8] though it has a fairly high integrated magnitude of 6.0. Despite this prominence, the Age of Aquarius will not dawn until the year 2597, as an astrological age does not begin until the Sun is in a particular constellation on the vernal equinox. Also, many of the stars that make up Aquarius have names that refer to good luck. It orbits its parent star every 3.36 days at a distance of 0.042 astronomical units (AU). [7] However, recent research has shown that there are several stars lying within its borders that possess planetary systems. Tienliecheng also has a disputed position; the 13-star castle replete with ramparts may have possessed Nu and Xi Aquarii but may instead have been located south in Piscis Austrinus. At magnitude 6.5, it is viewable in small-aperture instruments, but a 100 mm aperture telescope is needed to resolve any stars. # 3. [6], In Chinese astronomy, the stream of water flowing from the Water Jar was depicted as the "Army of Yu-Lin" (Yu-lin-kiun or Yulinjun). It is also a yellow supergiant located about 800 light years from Earth. WASP-6 b was discovered in 2008 by the transit method. [2] It was one of the 48 constellations listed by the 2nd century astronomer Ptolemy, and it remains one of the 88 modern constellations. Aquarius was also associated with the destructive floods that the Babylonians regularly experienced, and thus was negatively connoted. However, Aquarius is best seen in the spring in the Southern Hemisphere and the fall in the Northern Hemisphere. [8], The Iota Aquariids is a fairly weak meteor shower that peaks on 6 August, with a rate of approximately 8 meteors per hour.[8]. Aquarius is one of the 48 constellations listed by the Greek astronomer Ptolemy in the second century. Sadalmelik is the second brightest star in this constellation at magnitude 2.96. Naked-eye = 4 (city) It covers 0.25 square degrees, making it also the largest planetary nebula as seen from Earth. The normal meteors appear to have yellow trails. The name "Yu-lin" means "feathers and forests", referring to the numerous light-footed soldiers from the northern reaches of the empire represented by these faint stars. # 1. It shares an area of sky with other water constellations such as Cetus, the sea monster, Pisces, the fish, and Eridanus, the river. Space Exploration | Space Games | Space Gallery | Space Links, Visit Us on Facebook | Follow Us on Twitter. Nu, also the name for the 10th lunar mansion, was a handmaiden represented by Epsilon, Mu, 3, and 4 Aquarii. [6] 88, 89, and 98 Aquarii represent Fou-youe, the axes used as weapons and for hostage executions. Aquarius is the Latin word for such a water seller. Q&A Corner. [3] In Ancient Egypt astronomy, Aquarius was associated with the annual flood of the Nile; the banks were said to flood when Aquarius put his jar into the river, beginning spring. At magnitude 3.25, Skat is the third brightest star. [31] NGC 7293, also known as the Helix Nebula, is the closest planetary nebula to Earth at a distance of 650 light-years. Values listed apply primarily to stars. Aquarius constellation is faint and one of the largest constellations in the southern hemisphere. The planet was discovered by the radial velocity method in 2010 and has a mass of 2.2 Jupiter masses. [29] Of these, three are in the system's habitable zone, and may contain water. It is one of the largest globular clusters known to exist. [35], The Delta Aquariids is a double radiant meteor shower that peaks first on 29 July and second on 6 August. M72, also catalogued as NGC 6981, is a small 9th magnitude globular cluster located approximately 56,000 light-years from Earth. [8] Compared to the Helix Nebula, another planetary nebula in Aquarius, it is quite small. The celestial army was protected by the wall Leibizhen, which counted Iota, Lambda, Phi, and Sigma Aquarii among its 12 stars. Aquarius is one of the oldest of the recognized constellations along the zodiac (the Sun's apparent path). [14] It has a luminosity of 50 L☉. The Babylonian star-figure appears on entitlement stones and cylinder seals from the second millennium. Aquarius is not conspicuous, being chiefly marked by the stars gamma, zeta, eta, and pi, — the Urn, the familiar Y, — called by the Greeks Kalpe, Kalpis, Kalpeis, (water jar) and Situla, or Urna, by the Latins, Pliny making a distinct constellation of the latter, and by the line of fainter stars… The name in the Hindu zodiac is likewise kumbha "water-pitcher".[2]. Bear in mind that we will likely discover billions of exoplanets in the years to come. Deep-sky objects such as galaxies and nebulae are diffuse, so subtract an integer for these. Binoculars = 10 Gliese 876, one of the nearest stars to Earth at a distance of 15 light-years,[18] was the first red dwarf star to be found to possess a planetary system. * up to 8 with perfect eyes under ideal skies. 4" (100mm) telescope = 12.5 Also in Aquarius is Loui-pi-tchin, the ramparts that stretch from 29 and 27 Piscium and 33 and 30 Aquarii through Phi, Lambda, Sigma, and Iota Aquarii to Delta, Gamma, Kappa, and Epsilon Capricorni. There are three major meteor showers with radiants in Aquarius: the Eta Aquariids, the Delta Aquariids, and the Iota Aquariids. A star chart showing Aquarius and three deep-sky objects. The planet's mass is 2.9 times the mass of Jupiter, and its orbital period is 182 days. It's brightest star is Sadalsuud at magnitude 2.90. WASP-47 b was discovered in 2011 by the transit method, like WASP-6 b. [33] NGC 7252 is a tangle of stars resulting from the collision of two large galaxies and is known as the Atoms-for-Peace galaxy because of its resemblance to a cartoon atom.[34]. Aquarius is a constellation of the zodiac, situated between Capricornus and Pisces. [7], π Aquarii, also called Seat, is a B0 spectral type star with an apparent magnitude of 4.66 and an absolute magnitude of −4.1. The parent body of the shower is Halley's Comet, a periodic comet. Its name is water bearer in Latin and is introduced in the 2nd century CE by famous Greek astronomer Ptolemy. Its name is Latin for "water-carrier" or "cup-carrier", and its symbol is (Unicode ♒), a representation of water. Hubble space telescope = 30 [20] Gliese 849 is a red dwarf star orbited by the first known long-period Jupiter-like planet, Gliese 849 b. As of 2002[update], the Sun appears in the constellation Aquarius from 16 February to 11 March. His water jar, an asterism itself, consists of Gamma, Pi, Eta, and Zeta Aquarii; it pours water in a stream of more than 20 stars terminating with Fomalhaut, now assigned solely to Piscis Austrinus. The two are also moving through space perpendicular to the plane of the Milky Way. * For southern latitudes, flip the season listed. It contained the winter solstice in the Early Bronze Age. It is 2,200 times brighter that the Sun and contains six times its mass. It is represented as a man pouring water from a bucket into the mouth of the Southern Fish, depicted by the constellation Piscis Austrinus. The boundary of the Aquarius constellation contains 17 stars that host known exoplanets. M2 is a globular star cluster containing about 150,000 stars. They sailed for nine days before washing ashore on Mount Parnassus. [3][6] Aquarius is also sometimes identified with beautiful Ganymede, a youth in Greek mythology and the son of Trojan king Tros, who was taken to Mount Olympus by Zeus to act as cup-carrier to the gods. The star itself, barely below the threshold of naked-eye visibility at magnitude 7.6, is a G8IV (yellow subgiant) star located 131 parsecs from Earth. Wei, the rooftop and 12th lunar mansion, was a V-shaped constellation formed by Alpha Aquarii, Theta Pegasi, and Epsilon Pegasi; it shared its name with two other Chinese constellations, in modern-day Scorpius and Aries.[6].
