On July 6, 2004 a team of British astronomers using the Submillimetre Common-User Bolometer Array (SCUBA) of the James Clerk Maxwell Telescope in [[Hawaii]] announced they had found a debris disk ten times the mass of the debris (such as comets and asteroids) found in our own [[Solar System]].  The debris disk extends as far out as 55 AUs from the star and is believed created by collisions between comets and asteroids over time into smaller and smaller, more numerous pieces.<ref name="graves">http://adsabs.harvard.edu/abs/2004MNRAS.351L..54G</ref>  The total mass of the debris field is estimated to be 1.2 times the mass of the Earth based on modelling of the dust disk observations.  In comparison the debris of asteroids and comets in the Kuiper Belt only add up to 10% of the mass of Earth.<ref name="graves"/>
