Haneda-Campos

Haneda-Campos follows a distinctly cometary orbit: an eccentricity of 0.665 carries it from 1.101 AU at perihelion out to 5.479 AU at aphelion.

Orbit and dynamics

Between its closest point (1.101 AU) and its farthest (5.479 AU), the heliocentric distance changes by 4.378 AU over every revolution.

One full revolution takes 5.97 yr (2,180 days), computed from the semi-major axis of 3.29 AU.

The high eccentricity (0.665) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

The orbital plane is tilted 5.95° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 36.6 km/s at perihelion and falls to 7.4 km/s at aphelion.

Its Tisserand parameter with respect to Jupiter is T_J = 2.76, a standard discriminator between asteroidal and cometary dynamics.

Size and surface

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

Observation record and orbit quality

Astrometry from 62 individual observations underpins this orbit; the fit leaves an RMS residual of 0.7 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.
