PANSTARRS

PANSTARRS follows a distinctly cometary orbit: an eccentricity of 0.21 carries it from 3.478 AU at perihelion out to 5.332 AU at aphelion.

Orbit and dynamics

The path is an ellipse reaching 3.478 AU from the Sun at perihelion and 5.332 AU at aphelion, a radial span of 1.854 AU.

Applying Kepler's third law to a = 4.405 AU gives an orbital period of 9.25 yr, or about 3,377 days.

An eccentricity of 0.21 makes the orbit moderately elongated.

The orbital plane is tilted 6.75° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 17.6 km/s at perihelion and falls to 11.5 km/s at aphelion.

Its Tisserand parameter with respect to Jupiter is T_J = 2.97, 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 80 observations and has a weighted RMS residual of 0.3915 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.
