Orbit and dynamics
The path is an ellipse reaching 0.818 AU from the Sun at perihelion and 1.23 AU at aphelion, a radial span of 0.412 AU.
Applying Kepler's third law to a = 1.024 AU gives an orbital period of 1.04 yr, or about 378 days.
An eccentricity of 0.201 makes the orbit moderately elongated.
The orbital plane is tilted 5.93° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 36.1 km/s at perihelion and falls to 24 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 0.08 km, a value from direct size determination rather than from brightness alone.
A geometric albedo of 0.145 points to a comparatively bright, reflective surface.
Observation record and orbit quality
The current orbit solution is based on 62 observations and has a weighted RMS residual of 0.464 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.
