PANSTARRS

PANSTARRS follows a distinctly cometary orbit: an eccentricity of 0.252 carries it from 2.965 AU at perihelion out to 4.968 AU at aphelion.

Orbit and dynamics

The path is an ellipse reaching 2.965 AU from the Sun at perihelion and 4.968 AU at aphelion, a radial span of 2.003 AU.

Applying Kepler's third law to a = 3.967 AU gives an orbital period of 7.90 yr, or about 2,886 days.

An eccentricity of 0.252 makes the orbit moderately elongated.

The orbital plane is tilted 9.64° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 19.4 km/s at perihelion and falls to 11.6 km/s at aphelion.

Its Tisserand parameter with respect to Jupiter is T_J = 2.98, 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 53 observations and has a weighted RMS residual of 0.1999 arcseconds.

Condition code U = 5 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.
