Orbit and dynamics
The path is an ellipse reaching 1.416 AU from the Sun at perihelion and 5.556 AU at aphelion, a radial span of 4.14 AU.
Applying Kepler's third law to a = 3.486 AU gives an orbital period of 6.51 yr, or about 2,377 days.
The high eccentricity (0.594) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.
Its inclination of 4.7° keeps it close to the plane of the ecliptic.
By the vis-viva equation its orbital speed rises to 31.6 km/s at perihelion and falls to 8.1 km/s at aphelion.
Its Tisserand parameter with respect to Jupiter is T_J = 2.81, a standard discriminator between asteroidal and cometary dynamics.
Size and surface
Neither a measured diameter nor a reliable absolute magnitude is available for PANSTARRS, so its physical size remains unconstrained.
Observation record and orbit quality
The current orbit solution is based on 105 observations and has a weighted RMS residual of 0.626 arcseconds.
Condition code U = 5 indicates a moderately constrained orbit; predictions decades ahead still carry noticeable uncertainty.
About these computed values
Orbital periods, perihelion and aphelion speeds, and diameter estimates on this page are computed by SpaceAtlas from the JPL SBDB orbital elements. They are derived quantities, not values copied from the source catalogue.
