Period
Given the orbital eccentricity of this object, different epochs can generate quite different heliocentric unperturbed two-body best-fit solutions to the aphelion distance (maximum distance) of this object. For objects at such high eccentricity, the Suns barycentric coordinates are more stable than heliocentric coordinates. Using JPL Horizons the barycentric orbital elements for epoch 2011-Jan-01 generate a semi-major axis of 537 AU and a period of approximately 12,500 years. This gives it a barycentric orbital period just a little larger than Sedna.

Famous quotes containing the word period:
“Of all the barbarous middle ages, that
Which is most barbarous is the middle age
Of man! it is—I really scarce know what;
But when we hover between fool and sage,
And don’t know justly what we would be at—
A period something like a printed page,
Black letter upon foolscap, while our hair
Grows grizzled, and we are not what we were.”
—George Gordon Noel Byron (1788–1824)
“There is a period in the history of the individual, as of the race, when the hunters are the “best men,” as the Algonquins called them.”
—Henry David Thoreau (1817–1862)
“There is always a period when a man with a beard shaves it off. This period does not last. He returns headlong to his beard.”
—Jean Cocteau (1889–1963)
