PANSTARRS

PANSTARRS follows a distinctly cometary orbit: an eccentricity of 0.409 carries it from 2.104 AU at perihelion out to 5.016 AU at aphelion.

comet Observations: 414

Orbit and dynamics

Between its closest point (2.104 AU) and its farthest (5.016 AU), the heliocentric distance changes by 2.912 AU over every revolution.

One full revolution takes 6.72 yr (2,453 days), computed from the semi-major axis of 3.56 AU.

The high eccentricity (0.409) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

The orbital plane is tilted 10.93° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 24.4 km/s at perihelion and falls to 10.2 km/s at aphelion.

Its Tisserand parameter with respect to Jupiter is T_J = 2.94, 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 414 individual observations underpins this orbit; the fit leaves an RMS residual of 0.5391 arcseconds.

Condition code U = 0 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.
