Orbit and dynamics
The path is an ellipse reaching 0.932 AU from the Sun at perihelion and 2.474 AU at aphelion, a radial span of 1.542 AU.
Applying Kepler's third law to a = 1.703 AU gives an orbital period of 2.22 yr, or about 812 days.
The high eccentricity (0.453) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.
The orbital plane is tilted 12.08° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 37.2 km/s at perihelion and falls to 14 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 0.21 km, a value from direct size determination rather than from brightness alone.
A geometric albedo of 0.123 points to a comparatively bright, reflective surface.
Observation record and orbit quality
The current orbit solution is based on 55 observations and has a weighted RMS residual of 0.526 arcseconds.
Condition code U = 1 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.
