SIPS 1259-4336 is a nearby red dwarf star, located in constellation Centaurus at 11.8 light-years from Earth,[1] or, according unpublished RECONS trigonometric distance estimate, taken from website en.allexperts.com, at 25.4 light-years from Earth.[2]

History of observations

Discovery of SIPS 1259-4336 was published in 2005 by Deacon et al. The star was detected by its high proper motion from the Southern Infrared Proper Motion Survey (SIPS).[1]

Distance

As of March 2015, there are no published distance estimates of SIPS 1259-4336 besides trigonometric parallax with high uncertainty from the star's discovery paper: 276±41 mas.[1]

However, there is an unpublished trigonometric distance estimate from website en.allexperts.com: Tom Whiting e-mailed Todd Henry from RECONS team around 2008, and the reply was that theirs unpublished distance estimate of SIPS 1259-4336 is 7.79±0.05 parsecs (25.4±0.2 light-years).[2]
