Fuls

Fuls follows a distinctly cometary orbit: an eccentricity of 0.452 carries it from 3.797 AU at perihelion out to 10.069 AU at aphelion.

Orbit and dynamics

Between its closest point (3.797 AU) and its farthest (10.069 AU), the heliocentric distance changes by 6.272 AU over every revolution.

One full revolution takes 18.3 yr (6,668 days), computed from the semi-major axis of 6.933 AU.

The high eccentricity (0.452) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

The orbital plane is tilted 13.06° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 18.4 km/s at perihelion and falls to 6.9 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 Fuls, so its physical size remains unconstrained.

Observation record and orbit quality

Astrometry from 1,068 individual observations underpins this orbit; the fit leaves an RMS residual of 0.3884 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.
