PANSTARRS

PANSTARRS follows a distinctly cometary orbit: an eccentricity of 0.382 carries it from 5.976 AU at perihelion out to 13.376 AU at aphelion.

Orbit and dynamics

The path is an ellipse reaching 5.976 AU from the Sun at perihelion and 13.376 AU at aphelion, a radial span of 7.4 AU.

Applying Kepler's third law to a = 9.676 AU gives an orbital period of 30.1 yr, or about 10,993 days.

An eccentricity of 0.382 makes the orbit moderately elongated.

The orbital plane is tilted 18.03° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 14.3 km/s at perihelion and falls to 6.4 km/s at aphelion.

Its Tisserand parameter with respect to Jupiter is T_J = 2.93, 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 92 observations and has a weighted RMS residual of 0.3645 arcseconds.

Condition code U = 4 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.
