PANSTARRS

PANSTARRS follows a distinctly cometary orbit: an eccentricity of 1 carries it from 2.48 AU at perihelion out to 26,697 AU at aphelion.

Orbit and dynamics

Between its closest point (2.48 AU) and its farthest (26,697 AU), the heliocentric distance changes by 26,695 AU over every revolution.

One full revolution takes 1,542,488 yr (563,393,878 days), computed from the semi-major axis of 13,350 AU.

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 63.01° carries it well above and below the ecliptic plane.

By the vis-viva equation its orbital speed rises to 26.7 km/s at perihelion and falls to 0 km/s at aphelion.

Its Tisserand parameter with respect to Jupiter is T_J = 0.92, 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

Astrometry from 455 individual observations underpins this orbit; the fit leaves an RMS residual of 0.3745 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.
