LONEOS-PANSTARRS

LONEOS-PANSTARRS follows a distinctly cometary orbit: an eccentricity of 0.578 carries it from 2.063 AU at perihelion out to 7.713 AU at aphelion.

Orbit and dynamics

Between its closest point (2.063 AU) and its farthest (7.713 AU), the heliocentric distance changes by 5.65 AU over every revolution.

One full revolution takes 10.8 yr (3,947 days), computed from the semi-major axis of 4.888 AU.

The high eccentricity (0.578) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

The orbital plane is tilted 7.03° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 26 km/s at perihelion and falls to 7 km/s at aphelion.

Its Tisserand parameter with respect to Jupiter is T_J = 2.63, a standard discriminator between asteroidal and cometary dynamics.

Size and surface

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

Observation record and orbit quality

Astrometry from 182 individual observations underpins this orbit; the fit leaves an RMS residual of 0.4903 arcseconds.

Condition code U = 2 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.
