Jackson-Neujmin

Jackson-Neujmin follows a distinctly cometary orbit: an eccentricity of 0.66 carries it from 1.389 AU at perihelion out to 6.791 AU at aphelion.

Orbit and dynamics

The path is an ellipse reaching 1.389 AU from the Sun at perihelion and 6.791 AU at aphelion, a radial span of 5.402 AU.

Applying Kepler's third law to a = 4.09 AU gives an orbital period of 8.27 yr, or about 3,021 days.

The high eccentricity (0.66) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

The orbital plane is tilted 13.46° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 32.6 km/s at perihelion and falls to 6.7 km/s at aphelion.

Its Tisserand parameter with respect to Jupiter is T_J = 2.57, a standard discriminator between asteroidal and cometary dynamics.

Size and surface

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

Observation record and orbit quality

The current orbit solution is based on 378 observations and has a weighted RMS residual of 0.8824 arcseconds.

Condition code U = 3 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.
