Sedna is not a planet, according to the International Astronomical Union (IAU). Because Sedna is so distant and so small, it has not yet been classified, but is probably a Trans-Neptunian Object. It may or may not turn out to meet the standards of a "dwarf planet", depending on whether its mass is high enough to force it into a roughly spherical shape.
Sedna's orbit is highly elliptical and has not been completely analyzed, but its perihelion appears to be 76 AU with an aphelion of 975 AU. This would give it an orbital period of perhaps 12 thousand years.
A year on Sedna, a distant dwarf planet in our solar system, is approximately 11,400 Earth years. Sedna's orbit is highly elliptical and takes it to the outer reaches of the solar system, resulting in a significantly longer orbital period compared to planets closer to the Sun.
Sedna's orbit isn't known exactly yet, but it is estimated to take between 10,000 and 12,000 years to make one trip around the sun.
Sedna is thought to take around 11,400 years to complete one orbit of our sun.
