Orbit and dynamics
The path is an ellipse reaching 0.516 AU from the Sun at perihelion and 2.588 AU at aphelion, a radial span of 2.072 AU.
Applying Kepler's third law to a = 1.552 AU gives an orbital period of 1.93 yr, or about 706 days.
The high eccentricity (0.667) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.
Its inclination of 0.86° keeps it close to the plane of the ecliptic.
By the vis-viva equation its orbital speed rises to 53.5 km/s at perihelion and falls to 10.7 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
No direct size measurement is available; from an absolute magnitude of H = 23.51 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.07 km.
Observation record and orbit quality
The current orbit solution is based on 35 observations and has a weighted RMS residual of 0.6876 arcseconds.
Condition code U = 2 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.
