PANSTARRS

PANSTARRS follows a distinctly cometary orbit: an eccentricity of 0.242 carries it from 3.526 AU at perihelion out to 5.774 AU at aphelion.

Orbit and dynamics

Between its closest point (3.526 AU) and its farthest (5.774 AU), the heliocentric distance changes by 2.248 AU over every revolution.

One full revolution takes 10.0 yr (3,662 days), computed from the semi-major axis of 4.65 AU.

An eccentricity of 0.242 makes the orbit moderately elongated.

The orbital plane is tilted 13.7° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 17.7 km/s at perihelion and falls to 10.8 km/s at aphelion.

Its Tisserand parameter with respect to Jupiter is T_J = 2.9, 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 95 individual observations underpins this orbit; the fit leaves an RMS residual of 0.4314 arcseconds.

Condition code U = 1 means the orbit is very well determined, leaving only a small uncertainty in the future ephemeris.

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.
