Orbit and dynamics
The path is an ellipse reaching 0.871 AU from the Sun at perihelion and 3.027 AU at aphelion, a radial span of 2.156 AU.
Applying Kepler's third law to a = 1.949 AU gives an orbital period of 2.72 yr, or about 994 days.
The high eccentricity (0.553) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.
Its inclination of 1.55° keeps it close to the plane of the ecliptic.
By the vis-viva equation its orbital speed rises to 39.8 km/s at perihelion and falls to 11.4 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 0.04 km, a value from direct size determination rather than from brightness alone.
A geometric albedo of 0.288 points to a comparatively bright, reflective surface.
Observation record and orbit quality
The current orbit solution is based on 33 observations and has a weighted RMS residual of 0.4909 arcseconds.
Condition code U = 7 signals a poorly constrained orbit, so its future path should be treated as provisional.
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.
