Orbit and dynamics
The path is an ellipse reaching 1.027 AU from the Sun at perihelion and 1.755 AU at aphelion, a radial span of 0.728 AU.
Applying Kepler's third law to a = 1.391 AU gives an orbital period of 1.64 yr, or about 599 days.
An eccentricity of 0.262 makes the orbit moderately elongated.
A steep inclination of 31.22° carries it well above and below the ecliptic plane.
By the vis-viva equation its orbital speed rises to 33 km/s at perihelion and falls to 19.3 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
The measured diameter is 0.31 km, a value from direct size determination rather than from brightness alone.
A geometric albedo of 0.266 points to a comparatively bright, reflective surface.
Observation record and orbit quality
The current orbit solution is based on 291 observations and has a weighted RMS residual of 0.3594 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.
