Pimentel

Pimentel follows a distinctly cometary orbit: an eccentricity of 0.754 carries it from 1.819 AU at perihelion out to 12.993 AU at aphelion.

Orbit and dynamics

The path is an ellipse reaching 1.819 AU from the Sun at perihelion and 12.993 AU at aphelion, a radial span of 11.174 AU.

Applying Kepler's third law to a = 7.406 AU gives an orbital period of 20.2 yr, or about 7,361 days.

The high eccentricity (0.754) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

A steep inclination of 146.2° carries it well above and below the ecliptic plane.

By the vis-viva equation its orbital speed rises to 29.3 km/s at perihelion and falls to 4.1 km/s at aphelion.

Its Tisserand parameter with respect to Jupiter is T_J = -0.6, a standard discriminator between asteroidal and cometary dynamics.

Size and surface

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

Observation record and orbit quality

The current orbit solution is based on 60 observations and has a weighted RMS residual of 0.6219 arcseconds.

Condition code U = 6 indicates a moderately constrained orbit; predictions decades ahead still carry noticeable uncertainty.

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.
