thest planet farthest away from thesun is pluto. this decision was based on the definition that a full planet must clear its orbit of other debris, which pluto does not do. 9 billion kilometers. however, in 2006, the international astronomical union reclassified pluto as a dwarf planet, meaning it no longer holds the status of a full-fledged planet. Still, for many years, pluto was considered the ninth planet in our solar system, orbiting the sun at an average distance of about 5. since then, the search for the true farthest object in our solar system has led scientists to discover other distant objects, some of which are even more distant than pluto That's the whole idea..
Not obvious, but once you see it — you'll see it everywhere.
the current recognized farthest object from the sun is not a planet but a dwarf planet called eris. Worth adding: discovered in 2005 by astronomer mike brown, eris orbits the sun at an average distance of about 9. 6 billion kilometers—nearly twice as far as pluto.
