δ Andromedae
Delta Andromedae, Latinized from δ Andromedae, is a triple star system in the northern constellation of Andromeda. The system is visible to the naked eye as a point of light with a combined apparent visual magnitude of 3.28. Based upon parallax measurements, it is located at a distance of approximately from the Sun. The system is drifting closer with a radial velocity of −10 km/s. In Chinese, (), meaning ''Legs (asterism)'', refers to an asterism consisting of δ Andromedae, η Andromedae, 65 Piscium, ζ Andromedae, ι Piscium, ε Andromedae, π Andromedae, ν Andromedae, μ Andromedae, β Andromedae, σ Piscium, τ Piscium, 91 Piscium, υ Piscium, φ Piscium, χ Piscium and ψ1 Piscium. Consequently, the Chinese name for δ Andromedae itself is (, en, the Fifth Star of Legs.) Apart from its Bayer designation, it was also given the title ''Delta'' by Elijah H. Burritt in his star atlas. This is a long-period spectroscopic binary with an orb ...

J2000
In astronomy, an epoch or reference epoch is a instant, moment in time used as a reference point for some time-varying astronomical quantity. It is useful for the celestial coordinates or orbital elements of a Astronomical object, celestial body, as they are subject to Perturbation (astronomy), perturbations and vary with time. These time-varying astronomical quantities might include, for example, the mean longitude or mean anomaly of a body, the node of its orbit relative to a reference plane, the direction of the apogee or Perihelion and aphelion, aphelion of its orbit, or the size of the major axis of its orbit. The main use of astronomical quantities specified in this way is to calculate other relevant parameters of motion, in order to predict future positions and velocities. The applied tools of the disciplines of celestial mechanics or its subfield orbital mechanics (for predicting orbital paths and positions for bodies in motion under the gravitational effects of other bodi ...

Elijah Hinsdale Burritt
Elijah ( ; he, אֵלִיָּהוּ, ʾĒlīyyāhū, meaning "My God is Yahweh/YHWH"; Greek form: Elias, ''Elías''; syr, ܐܸܠܝܼܵܐ, ''Elyāe''; Arabic: إلياس or إليا, ''Ilyās'' or ''Ilyā''. ) was, according to the Books of Kings in the Hebrew Bible, a prophet and a miracle worker who lived in the northern kingdom of Israel during the reign of King Ahab (9th century BCE). In 1 Kings 18, Elijah defended the worship of the Hebrew God over that of the Canaanite deity Baal. God also performed many miracles through Elijah, including resurrection, bringing fire down from the sky, and entering heaven alive "by fire". 2 Kings 2:11 He is also portrayed as leading a school of prophets known as "the sons of the prophets". Following his ascension, Elisha, his disciple and most devoted assistant, took over his role as leader of this school. The Book of Malachi prophesies Elijah's return "before the coming of the great and terrible day of the ", making him a harbinger of ...

Bayer Designation
A Bayer designation is a stellar designation in which a specific star is identified by a Greek or Latin letter followed by the genitive form of its parent constellation's Latin name. The original list of Bayer designations contained 1,564 stars. The brighter stars were assigned their first systematic names by the German astronomer Johann Bayer in 1603, in his star atlas ''Uranometria''. Bayer catalogued only a few stars too far south to be seen from Germany, but later astronomers (including Nicolas-Louis de Lacaille and Benjamin Apthorp Gould) supplemented Bayer's catalog with entries for southern constellations. Scheme Bayer assigned a lowercase Greek letter (alpha (α), beta (β), gamma (γ), etc.) or a Latin letter (A, b, c, etc.) to each star he catalogued, combined with the Latin name of the star's parent constellation in genitive (possessive) form. The constellation name is frequently abbreviated to a standard three-letter form. For example, Aldebaran in the constellation ...

Chinese Star Names
Chinese star names (Chinese: , ''xīng míng'') are named according to ancient Chinese astronomy and astrology. The sky is divided into star mansions (, ''xīng xiù'', also translated as "lodges") and asterisms (, ''xīng guān''). The system of 283 asterisms under Three Enclosures and Twenty-eight Mansions was established by Chen Zhuo of the Three Kingdoms period, who synthesized ancient constellations and the asterisms created by early astronomers Shi Shen, Gan De and Wuxian. Since the Han and Jin Dynasties, stars have been given reference numbers within their asterisms in a system similar to the Bayer or Flamsteed designations, so that individual stars can be identified. For example, Deneb (α Cyg) is referred to as (''Tiān Jīn Sì'', the Fourth Star of Celestial Ford). In the Qing Dynasty, Chinese knowledge of the sky was improved by the arrival of European star charts. ''Yixiang Kaocheng'', compiled in mid-18th century by then deputy Minister of Rites Ignaz Kögler, ...

The primary itself is a close binary, with two A-type stars that orbit each other every 14.44 years. Psi1 Piscium is moving through the Galaxy at a speed of 22.5 km/s relative to the Sun. Its projected Galactic orbit carries it between 22,800 and 24,300 light years from the center of the Galaxy.

Chi Piscium
Chi Piscium (χ Piscium) is a solitary, orange-hued star in the zodiac constellation of Pisces. It can be seen with the naked eye, having an apparent visual magnitude of +4.64. Based upon an annual parallax shift of 8.50 mas as seen from Earth, it is located about 384 light years from the Sun. This is an evolved G-type giant star with a stellar classification of G8.5 III. There is a 94% chance that it is on the horizontal branch and is a red clump star, which means it is generating energy through helium fusion at its core. Chi Piscium is estimated to have 3.17 times the mass of the Sun, nearly 21 times the solar radius, and shines with 209 times the Sun's luminosity. It is around 380 million years old.

Phi Piscium
Phi Piscium, Latinized from φ Piscium, is a quadruple star system approximately 380 light years away in the constellation Pisces. It consists of Phi Piscium A, with a spectral type of K0III, and Phi Piscium B. Phi Piscium A possesses a surface temperature of 3,500 to 5,000 kelvins. Some suggest the only visible companion in the Phi Piscium B sub-system is a late F dwarf star, while others suggest it is a K0 star. The invisible component of the Phi Piscium B sub-system is proposed to have a spectral type of M2V. The star system has a period of about 20½ years and has a notably high eccentricity of 0.815.

Sigma Piscium
Sigma Piscium (Sigma Psc, σ Piscium, σ Psc) is a main-sequence star in the zodiac constellation of Pisces. It has an apparent magnitude of +5.50, meaning it is barely visible to the naked eye, according to the Bortle scale. While parallax measurements by the Hipparcos spacecraft give a distance of approximately 430 light years (133 parsecs), dynamical parallax measurements put it slightly closer, at 368 light-years (113 parsecs) from Earth. Sigma Piscium is a spectroscopic binary system, meaning the components of the system have been detected from periodic Doppler shifts in their spectra. In this case, light from both stars can be detected and it is double-lined. It has an orbital period of 81 days, and the orbit is relatively eccentric, at about 0.9. Both components are B-type main-sequence stars. Sigma Piscium is moving through the Milky Way at a speed of 23.5 km/s relative to the Sun. Its projected galactic orbit carries it between 24,300 an ...
