RX J1856.5-3754


RX J1856.5-3754 (also called RX J185635-3754, RX J185635-375, and various other designations) is a nearby neutron star in the constellation Corona Australis.
==Discovery and location==
RX J1856.5-3754 is thought to have formed in a supernova explosion of its companion star about one million years ago and is moving at 108 km/s across the sky. It was discovered in 1992, and observations in 1996 confirmed that it is a neutron star, the closest to Earth discovered.〔Rees, Martin (2012) (''Universe'' ).
Dorling Kindersley. p. 528〕
It was originally thought to be about 150–200 light-years away,〔("The Mystery of the Lonely Neutron Star" ). European Southern Observatory press release, September 11, 2000. Accessed online at spaceref.com May 20, 2007.〕 but further observations using the Chandra X-ray Observatory in 2002 indicate that its distance is greater—about 400 light-years.〔〔
RX J1856 is one of the Magnificent Seven, a group of young neutron stars at distances between 200 and 500 parsecs (652 and 1630 light years) of Earth.
