The Henry Draper Catalogue ( HD) is an Astronomical Star catalogue published between 1918 and 1924 giving Spectroscopic classifications In Astronomy, an epoch is a moment in time used as a reference for the Orbital elements of a Celestial body. In Astronomy, an epoch is a moment in time used as a reference for the Orbital elements of a Celestial body. 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 Each culture has its own Constellations usually based on Mythology. Ophiuchus (Ὀφιοῦχος ˌɒfiːˈuːkəs is one of the 88 Constellations and was also one of the 48 listed by Ptolemy.

HD 149143 is a star located in Ophiuchus constellation that has spectral type of G0 located at a distance of 207 ly from us. 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 In Astronomy, Durchmusterung or Bonner Durchmusterung ( BD) is the usual name for three comprehensive astrometric Star catalogues The Hipparcos and Tycho Catalogues (Tycho-1 are the primary products of the European Space Agency 's astrometric mission Hipparcos. The Smithsonian Astrophysical Observatory Star Catalog is an astrometric Star catalogue. A star is a massive luminous ball of plasma. The nearest star to Earth is the Sun, which is the source of most of the Energy on Earth Ophiuchus (Ὀφιοῦχος ˌɒfiːˈuːkəs is one of the 88 Constellations and was also one of the 48 listed by Ptolemy. In Astronomy, stellar classification is a classification of Stars based initially on photospheric temperature and its associated Spectral characteristics The cosmic distance ladder (also known as the Extragalactic Distance Scale) is the succession of methods by which astronomers determine the Distances to celestial Its apparent magnitude of the star is 7. 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 9 (binocular object) and the absolute magnitude is 3. In Astronomy, absolute magnitude (also known as absolute visual magnitude) is the Apparent magnitude an object would have if it were at a standard 9 (naked-eye object).
