Yes, there is a celestial object called Sedna (90377 Sedna), which is a dwarf planet candidate orbiting far beyond Neptune and Pluto. Its closest approach to the Sun is about 1.5 times the maximum for Pluto, with an extreme elliptical orbit varying from 76 AU to 975 AU.
As the farthest identified object orbiting the Sun, Sedna takes about 12,000 Earth years to complete one orbit. It will reach its next closest approach to the Sun in the year 2075. Only the dwarf planet Eris is current farther from the Sun.
Its size is estimated at approximately three-quarters the size of Pluto, or about 1,000 miles (1200-1600 km) in diameter.

More on Sedna
Sedna rotates very slowly. It takes at least 20 days to complete a rotation, maybe as long as 50 days. The gravitational pull of a moon would be the best explanation for this slow rotation. Almost all other minor bodies in the solar system rotate in a matter of hours. Pluto has a six-day rotation because it has a satellite, Charon. But Sedna has no moon.
