PANSTARRS

PANSTARRS follows a distinctly cometary orbit: an eccentricity of 1 carries it from 9.216 AU at perihelion out to 255,187 AU at aphelion.

Orbit and dynamics

The path is an ellipse reaching 9.216 AU from the Sun at perihelion and 255,187 AU at aphelion, a radial span of 255,178 AU.

Applying Kepler's third law to a = 127,600 AU gives an orbital period of 45,580,177 yr, or about 16,648,159,812 days.

The high eccentricity (1) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

A steep inclination of 32.43° carries it well above and below the ecliptic plane.

By the vis-viva equation its orbital speed rises to 13.9 km/s at perihelion and falls to 0 km/s at aphelion.

Its Tisserand parameter with respect to Jupiter is T_J = 3.74, 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 85 observations and has a weighted RMS residual of 0.5326 arcseconds.

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.
