PANSTARRS

PANSTARRS follows a distinctly cometary orbit: an eccentricity of 0.17 carries it from 2.287 AU at perihelion out to 3.222 AU at aphelion.

comet Observations: 46

Orbit and dynamics

The path is an ellipse reaching 2.287 AU from the Sun at perihelion and 3.222 AU at aphelion, a radial span of 0.935 AU.

Applying Kepler's third law to a = 2.755 AU gives an orbital period of 4.57 yr, or about 1,670 days.

An eccentricity of 0.17 makes the orbit moderately elongated.

Its inclination of 4.56° keeps it close to the plane of the ecliptic.

By the vis-viva equation its orbital speed rises to 21.3 km/s at perihelion and falls to 15.1 km/s at aphelion.

Its Tisserand parameter with respect to Jupiter is T_J = 3.32, 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 46 observations and has a weighted RMS residual of 0.3478 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.
