The Bayer designation Chi Sagittarii (χ Sgr / χ Sagittarii) is shared by three star systems in the constellation Sagittarius. A Bayer designation is a stellar designation in which a specific star is identified by a Greek letter, followed by the genitive form of its parent constellation's 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 The brightest of these, χ¹ Sagittarii and χ³ Sagittarii are separated by 0. 56° on the sky. The dimmer χ² Sagittarii is located between them, 0. 10° from χ¹.

χ¹ Sagittarii

Chi-1 Sagittarii is a binary star. 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 binary star is a Star system consisting of two Stars orbiting around their Center of mass. The primary is a spectral type A5 dwarf. In Astronomy, stellar classification is a classification of Stars based initially on photospheric temperature and its associated Spectral characteristics The main sequence is the name for a continuous and distinctive band of stars that appear on a plot of stellar color versus brightness The companion is approximately 0. 12 arcseconds from the primary, putting it about 8 Astronomical Units away. 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 orbital period is 10. The orbital period is the time taken for a given object to make one complete Orbit about another object 8 years. The combined apparent magnitude of the system is +5. 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 02. It is approximately 220 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

χ² Sagittarii

Chi-2 Sagittarii is a spectral type B7 subgiant which has an apparent magnitude of +7. 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 The Henry Draper Catalogue ( HD) is an Astronomical Star catalogue published between 1918 and 1924 giving Spectroscopic classifications Hipparcos (an Acronym for Hi gh P recision Par allax Co llecting S atellite) was an Astrometry mission In Astronomy, stellar classification is a classification of Stars based initially on photospheric temperature and its associated Spectral characteristics Subgiant star is a class of Stars that are slightly brighter than normal Main sequence (dwarf stars of the same spectral class but not as bright as 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 26. It is approximately 1200 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

χ³ Sagittarii

Chi-3 Sagittarii is a spectral type K3 giant which has an apparent magnitude of +5. 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 In Astronomy, stellar classification is a classification of Stars based initially on photospheric temperature and its associated Spectral characteristics A giant star is a Star with substantially larger Radius and Luminosity than a Main sequence star of the same surface temperature. 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 45. It is 506 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
