New Planetoid Found in Solar System – Most Distant YetPublication: National Geographic News Date: March 15, 2004 View Article
Astronomers announced Monday the discovery of the most distant object ever found orbiting the sun: a shiny, red body of rock and ice about three-quarters the size of Pluto. The plantoid is so far out that it takes 10,000 years to circle the sun.
“There is absolutely nothing else like it known in the solar system,” said Mike Brown. Brown is a planetary astronomer at the California Institute of Technology in Pasadena and leader of the research team.
