CallUrl('www>obliquity>comhtml',0), Proper motion is generally measured in seconds of arc per year; the largest known is that of Barnard's star in the constellation ~TildeLink(), about 10" yearly. It has a visual magnitude of 9.54 and is only 5.980 light years distant from Earth. It was discovered by the German-American astronomer Rudolph Minkowski is 1947. In 2010, another brown dwarf companion was discovered, one with at least 24.5 Jupiter masses and an orbital period of 3,169 days. The prototypical T Tauri star - T Tauri itself - is part of a close binary system with a smaller, fainter companion. The cluster is about 75 light years in diameter, and the brightest stars in it are of 12th magnitude.

The star has a confirmed planet in its orbit. The third component is classified as an RS Canum Venaticorum variable, a close binary star with an active chromosphere that can cause large stellar spots, which in turn cause variations in brightness. The proper names of stars that have been officially approved by the International Astronomical Union (IAU) are Barnard’s Star, Cebalrai, Guniibuu, Mahsati, Marfik, Rasalhague, Rosalíadecastro, Sabik, Timir, Yed Posterior, and Yed Prior. GJ 1214b has a radius of about 2.7 times that of Earth and is about 6.5 times as massive, putting it squarely into the class of exoplanets known as super-Earths. One of the closest stars to Earth and the star with the largest proper motion. Delta Ophiuchi is a red giant with the stellar classification of M0.5 III. The cluster has an estimated age of less than 40 million years. The star’s traditional name, Celbalrai (and variants Cheleb and Kelb Alrai) comes from the Arabic kalb al-rā‘ī, which means “the shepherd dog.”. It is pronounced /ˌɒfiːˈjuːkəs/ (off-ee-YOO-cuss).

Pollux is a main star in the constellation Gemini and makes up the constellation outline. Geocentric Coordinates of Stars. It forms an optical double with the star Epsilon Ophiuchi, or Yed Posterior. Of the 13 zodiac constellations (constellations that can contain the Sun during the course of a year), Ophiuchus is the only one which is not counted as an astrological sign.
