PANSTARRS

PANSTARRS follows a distinctly cometary orbit: an eccentricity of 0.266 carries it from 3.34 AU at perihelion out to 5.76 AU at aphelion.

Orbit and dynamics

The path is an ellipse reaching 3.34 AU from the Sun at perihelion and 5.76 AU at aphelion, a radial span of 2.42 AU.

Applying Kepler's third law to a = 4.55 AU gives an orbital period of 9.71 yr, or about 3,545 days.

An eccentricity of 0.266 makes the orbit moderately elongated.

A steep inclination of 23.46° carries it well above and below the ecliptic plane.

By the vis-viva equation its orbital speed rises to 18.3 km/s at perihelion and falls to 10.6 km/s at aphelion.

Its Tisserand parameter with respect to Jupiter is T_J = 2.8, 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 78 observations and has a weighted RMS residual of 0.5191 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.
