PANSTARRS-Christensen

PANSTARRS-Christensen follows a distinctly cometary orbit: an eccentricity of 0.284 carries it from 2.956 AU at perihelion out to 5.308 AU at aphelion.

Orbit and dynamics

The path is an ellipse reaching 2.956 AU from the Sun at perihelion and 5.308 AU at aphelion, a radial span of 2.352 AU.

Applying Kepler's third law to a = 4.132 AU gives an orbital period of 8.40 yr, or about 3,068 days.

An eccentricity of 0.284 makes the orbit moderately elongated.

The orbital plane is tilted 19.89° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 19.6 km/s at perihelion and falls to 10.9 km/s at aphelion.

Its Tisserand parameter with respect to Jupiter is T_J = 2.87, a standard discriminator between asteroidal and cometary dynamics.

Size and surface

Neither a measured diameter nor a reliable absolute magnitude is available for PANSTARRS-Christensen, so its physical size remains unconstrained.

Observation record and orbit quality

The current orbit solution is based on 215 observations and has a weighted RMS residual of 0.4538 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.
