An astronomer at the University of Hawaii has spied the most distant object
yet observed in the Solar System. Dave Jewitt, who discovered the object last
month, says it lies 7.3 billion kilometres from the Sun. Although some comets go
out much farther, as will Pluto at the outermost part of its irregular orbit, no
Solar System body has previously been viewed at such a huge distance from the
Sun. The new object, called 1999 CZ118, seems to be between 75 and 150
kilometres across.
