Orbit and dynamics
Between its closest point (0.774 AU) and its farthest (1.938 AU), the heliocentric distance changes by 1.164 AU over every revolution.
One full revolution takes 1.58 yr (577 days), computed from the semi-major axis of 1.356 AU.
The high eccentricity (0.429) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.
The orbital plane is tilted 13.99° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 40.5 km/s at perihelion and falls to 16.2 km/s at aphelion.
Because q < 1 AU and Q > 1 AU, this orbit geometrically intersects the region of Earth's orbit.
Size and surface
The measured diameter is 0.56 km, a value from direct size determination rather than from brightness alone.
Its geometric albedo of 0.099 indicates a very dark, carbonaceous-type surface.
Observation record and orbit quality
Astrometry from 291 individual observations underpins this orbit; the fit leaves an RMS residual of 0.4007 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.
