Boethin

Boethin follows a distinctly cometary orbit: an eccentricity of 0.781 carries it from 1.135 AU at perihelion out to 9.236 AU at aphelion.

Orbit and dynamics

Between its closest point (1.135 AU) and its farthest (9.236 AU), the heliocentric distance changes by 8.101 AU over every revolution.

One full revolution takes 11.8 yr (4,312 days), computed from the semi-major axis of 5.185 AU.

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

Its inclination of 4.3° keeps it close to the plane of the ecliptic.

By the vis-viva equation its orbital speed rises to 37.3 km/s at perihelion and falls to 4.6 km/s at aphelion.

Its Tisserand parameter with respect to Jupiter is T_J = 2.25, a standard discriminator between asteroidal and cometary dynamics.

Size and surface

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

Observation record and orbit quality

Astrometry from 51 individual observations underpins this orbit; the fit leaves an RMS residual of 1.6569 arcseconds.

Condition code U = 8 signals a poorly constrained orbit, so its future path should be treated as provisional.

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.
