Orbit and dynamics
Between its closest point (2.055 AU) and its farthest (9.119 AU), the heliocentric distance changes by 7.064 AU over every revolution.
One full revolution takes 13.2 yr (4,823 days), computed from the semi-major axis of 5.587 AU.
The high eccentricity (0.632) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.
The orbital plane is tilted 10.53° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 26.5 km/s at perihelion and falls to 6 km/s at aphelion.
Its Tisserand parameter with respect to Jupiter is T_J = 2.51, a standard discriminator between asteroidal and cometary dynamics.
Size and surface
Neither a measured diameter nor a reliable absolute magnitude is available for Spacewatch-PANSTARRS, so its physical size remains unconstrained.
Observation record and orbit quality
Astrometry from 174 individual observations underpins this orbit; the fit leaves an RMS residual of 0.6267 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.
