Pi Sagittarii (π Sgr / π Sagittarii) is a triple star system in the constellation Sagittarius. The cosmic distance ladder (also known as the Extragalactic Distance Scale) is the succession of methods by which astronomers determine the Distances to celestial A light-year or light year (symbol ly) is a unit of Length, equal to just under ten trillion Kilometres As defined by History The first direct measurements of an object at interstellar distances were undertaken by German Astronomer Friedrich Wilhelm Bessel in 1838 In Astronomy, stellar classification is a classification of Stars based initially on photospheric temperature and its associated Spectral characteristics A star catalogue, or star catalog, is an Astronomical catalogue that lists Stars In Astronomy, many stars are referred to simply by catalogue A star catalogue, or star catalog, is an Astronomical catalogue that lists Stars In Astronomy, many stars are referred to simply by catalogue The Henry Draper Catalogue ( HD) is an Astronomical Star catalogue published between 1918 and 1924 giving Spectroscopic classifications A star catalogue, or star catalog, is an Astronomical catalogue that lists Stars In Astronomy, many stars are referred to simply by catalogue Hipparcos (an Acronym for Hi gh P recision Par allax Co llecting S atellite) was an Astrometry mission A star system or stellar system is a small number of Stars which orbit each other bound by gravitational attraction. In common usage a constellation is a group of celestial bodies that are connected together in some arrangement typically stars to form a visible figure or picture It also has the traditional name Albaldah. It is known as 建三 (the Third Star of the Establishment) in Chinese. The star is 440 light years from Earth. A light-year or light year (symbol ly) is a unit of Length, equal to just under ten trillion Kilometres As defined by EARTH was a short-lived Japanese vocal trio which released 6 singles and 1 album between 2000 and 2001

Albaldah has an apparent magnitude of +2. The apparent magnitude ( m) of a celestial body is a measure of its Brightness as seen by an observer on Earth, normalized to the value 88 and belongs to the spectral class F2II. In Astronomy, stellar classification is a classification of Stars based initially on photospheric temperature and its associated Spectral characteristics Albaldah has two companions in close orbits. Pi Sagittarii B is located 0. 1 arcseconds from Albaldah, or at least 13 Astronomical Units (AU). A minute of arc, arcminute, or MOA is a unit of angular measurement, equal to one sixtieth (1/60 of one degree. The astronomical unit ( AU or au or au or sometimes ua) is a unit of Length based on the distance from the Earth to the The second companion, the 6th magnitude Pi Sagittarii C, is 0. 4 arcseconds away, or at least 40 AU.

Because it is close to the ecliptic, Albaldah can sometimes be occulted by the Moon, and very rarely, planets of our solar system. The ecliptic is the apparent path that the Sun traces out in the sky during the year In Shia Islam The Occultation is a term used to designate the hidden state of the Imam of the Time. A planet, as defined by the International Astronomical Union (IAU is a celestial body Orbiting a Star or stellar remnant that is The next occultation by a planet takes place on February 17, 2035 when it will be occulted by Venus.

Etymology

The name Albalda comes from the Arabic البلطة al-balţah 'the axe' (or 'the city'?). Arabic (ar الْعَرَبيّة (informally ar عَرَبيْ) in terms of the number of speakers is the largest living member of the Semitic language
