Skiff

Skiff follows a distinctly cometary orbit: an eccentricity of 0.416 carries it from 2.421 AU at perihelion out to 5.875 AU at aphelion.

Orbit and dynamics

The path is an ellipse reaching 2.421 AU from the Sun at perihelion and 5.875 AU at aphelion, a radial span of 3.454 AU.

Applying Kepler's third law to a = 4.148 AU gives an orbital period of 8.45 yr, or about 3,086 days.

The high eccentricity (0.416) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

A steep inclination of 27.05° carries it well above and below the ecliptic plane.

By the vis-viva equation its orbital speed rises to 22.8 km/s at perihelion and falls to 9.4 km/s at aphelion.

Its Tisserand parameter with respect to Jupiter is T_J = 2.7, a standard discriminator between asteroidal and cometary dynamics.

Size and surface

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

Observation record and orbit quality

The current orbit solution is based on 786 observations and has a weighted RMS residual of 0.6001 arcseconds.

Condition code U = 0 means the orbit is very well determined, leaving only a small uncertainty in the future ephemeris.

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.
