Orbit and dynamics
The path is an ellipse reaching 0.362 AU from the Sun at perihelion and 1.866 AU at aphelion, a radial span of 1.504 AU.
Applying Kepler's third law to a = 1.114 AU gives an orbital period of 1.18 yr, or about 429 days.
The high eccentricity (0.675) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.
Its inclination of 3.05° keeps it close to the plane of the ecliptic.
By the vis-viva equation its orbital speed rises to 64.1 km/s at perihelion and falls to 12.4 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 0.49 km, a value from direct size determination rather than from brightness alone.
A geometric albedo of 0.118 points to a comparatively bright, reflective surface.
Observation record and orbit quality
The current orbit solution is based on 437 observations and has a weighted RMS residual of 0.4906 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.
