Orbit and dynamics
The path is an ellipse reaching 1.103 AU from the Sun at perihelion and 1.301 AU at aphelion, a radial span of 0.198 AU.
Applying Kepler's third law to a = 1.202 AU gives an orbital period of 1.32 yr, or about 481 days.
With e = 0.083, the orbit is close to circular.
The orbital plane is tilted 7.41° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 29.5 km/s at perihelion and falls to 25 km/s at aphelion.
Its perihelion lies just outside Earth's orbit, which is why it is classed as Earth-approaching rather than Earth-crossing.
Size and surface
No direct size measurement is available; from an absolute magnitude of H = 19.41 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.47 km.
Observation record and orbit quality
The current orbit solution is based on 1,039 observations and has a weighted RMS residual of 0.4178 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.
