Alpha Sextantis

Alpha Sextantis (α Sex, α Sextantis) is the brightest star in the constellation Sextans.〔(The Internet Encyclopedia of Science ) Retrieved 24 May, 2009〕 It is a white A-type giant with an apparent magnitude of +4.48. It is approximately 287 light years from Earth.
Alpha Sextantis is considered an informal "equator star", as it lies less than a quarter of a degree south of the celestial equator. In 1900, it was 7 minutes of arc north of the equator. As a result of movement of the Earth's axial tilt, it crossed over to the Southern Hemisphere in December 1923.〔(Department of Astronomy, University of Illinois ) Retrieved 24 May, 2009〕
