Orbit and dynamics
The path is an ellipse reaching 0.852 AU from the Sun at perihelion and 1.79 AU at aphelion, a radial span of 0.938 AU.
Applying Kepler's third law to a = 1.321 AU gives an orbital period of 1.52 yr, or about 555 days.
An eccentricity of 0.355 makes the orbit moderately elongated.
The orbital plane is tilted 5.59° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 37.6 km/s at perihelion and falls to 17.9 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 0.21 km, a value from direct size determination rather than from brightness alone.
A geometric albedo of 0.138 points to a comparatively bright, reflective surface.
Observation record and orbit quality
The current orbit solution is based on 380 observations and has a weighted RMS residual of 0.3618 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.
