Lemmon-PANSTARRS

Lemmon-PANSTARRS follows a distinctly cometary orbit: an eccentricity of 0.979 carries it from 2.399 AU at perihelion out to 227.4 AU at aphelion.

Orbit and dynamics

The path is an ellipse reaching 2.399 AU from the Sun at perihelion and 227.4 AU at aphelion, a radial span of 225.0 AU.

Applying Kepler's third law to a = 114.9 AU gives an orbital period of 1,232 yr, or about 449,853 days.

The high eccentricity (0.979) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

A steep inclination of 145.5° carries it well above and below the ecliptic plane.

By the vis-viva equation its orbital speed rises to 27.1 km/s at perihelion and falls to 0.3 km/s at aphelion.

Its Tisserand parameter with respect to Jupiter is T_J = -1.53, a standard discriminator between asteroidal and cometary dynamics.

Size and surface

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

Observation record and orbit quality

The current orbit solution is based on 76 observations and has a weighted RMS residual of 0.6894 arcseconds.

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.
