Holvorcem

Holvorcem follows a distinctly cometary orbit: an eccentricity of 0.781 carries it from 2.46 AU at perihelion out to 20 AU at aphelion.

Orbit and dynamics

The path is an ellipse reaching 2.46 AU from the Sun at perihelion and 20 AU at aphelion, a radial span of 17.54 AU.

Applying Kepler's third law to a = 11.23 AU gives an orbital period of 37.6 yr, or about 13,745 days.

The high eccentricity (0.781) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

The orbital plane is tilted 10.09° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 25.3 km/s at perihelion and falls to 3.1 km/s at aphelion.

Its Tisserand parameter with respect to Jupiter is T_J = 2.27, a standard discriminator between asteroidal and cometary dynamics.

Size and surface

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

Observation record and orbit quality

The current orbit solution is based on 118 observations and has a weighted RMS residual of 0.5097 arcseconds.

Condition code U = 4 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.
