Orbit and dynamics
Between its closest point (0.111 AU) and its farthest (2.333 AU), the heliocentric distance changes by 2.222 AU over every revolution.
One full revolution takes 1.35 yr (493 days), computed from the semi-major axis of 1.222 AU.
The high eccentricity (0.909) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.
The orbital plane is tilted 5.43° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 123.5 km/s at perihelion and falls to 5.9 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 0.37 km, a value from direct size determination rather than from brightness alone.
A geometric albedo of 0.128 points to a comparatively bright, reflective surface.
Observation record and orbit quality
Astrometry from 104 individual observations underpins this orbit; the fit leaves an RMS residual of 0.587 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.
