Orbit and dynamics
The path is an ellipse reaching 0.961 AU from the Sun at perihelion and 1.447 AU at aphelion, a radial span of 0.486 AU.
Applying Kepler's third law to a = 1.204 AU gives an orbital period of 1.32 yr, or about 483 days.
An eccentricity of 0.202 makes the orbit moderately elongated.
A steep inclination of 23.59° carries it well above and below the ecliptic plane.
By the vis-viva equation its orbital speed rises to 33.3 km/s at perihelion and falls to 22.1 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
No direct size measurement is available; from an absolute magnitude of H = 22.26 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.13 km.
Observation record and orbit quality
The current orbit solution is based on 42 observations and has a weighted RMS residual of 0.4025 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.
