Orbit and dynamics
The path is an ellipse reaching 1.075 AU from the Sun at perihelion and 1.142 AU at aphelion, a radial span of 0.067 AU.
Applying Kepler's third law to a = 1.109 AU gives an orbital period of 1.17 yr, or about 427 days.
With e = 0.03, the orbit is close to circular.
The orbital plane is tilted 14.16° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 29.2 km/s at perihelion and falls to 27.4 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 0.85 km, a value from direct size determination rather than from brightness alone.
A geometric albedo of 0.156 points to a comparatively bright, reflective surface.
Observation record and orbit quality
The current orbit solution is based on 2,129 observations and has a weighted RMS residual of 0.4146 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.
