Gibbs

Gibbs follows a distinctly cometary orbit: an eccentricity of 0.203 carries it from 6.894 AU at perihelion out to 10.41 AU at aphelion.

Orbit and dynamics

Between its closest point (6.894 AU) and its farthest (10.41 AU), the heliocentric distance changes by 3.516 AU over every revolution.

One full revolution takes 25.4 yr (9,295 days), computed from the semi-major axis of 8.652 AU.

An eccentricity of 0.203 makes the orbit moderately elongated.

Its inclination of 2.68° keeps it close to the plane of the ecliptic.

By the vis-viva equation its orbital speed rises to 12.4 km/s at perihelion and falls to 8.2 km/s at aphelion.

Its Tisserand parameter with respect to Jupiter is T_J = 3.12, a standard discriminator between asteroidal and cometary dynamics.

Size and surface

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

Observation record and orbit quality

Astrometry from 148 individual observations underpins this orbit; the fit leaves an RMS residual of 0.5421 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.
