Orbit and dynamics
Between its closest point (1.087 AU) and its farthest (2.941 AU), the heliocentric distance changes by 1.854 AU over every revolution.
One full revolution takes 2.86 yr (1,044 days), computed from the semi-major axis of 2.014 AU.
The high eccentricity (0.46) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.
A steep inclination of 56.1° carries it well above and below the ecliptic plane.
By the vis-viva equation its orbital speed rises to 34.5 km/s at perihelion and falls to 12.8 km/s at aphelion.
Its perihelion lies just outside Earth's orbit, which is why it is classed as Earth-approaching rather than Earth-crossing.
Size and surface
The measured diameter is 1.49 km, a value from direct size determination rather than from brightness alone.
Its geometric albedo of 0.035 indicates a very dark, carbonaceous-type surface.
Observation record and orbit quality
Astrometry from 130 individual observations underpins this orbit; the fit leaves an RMS residual of 0.4829 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.
