Orbit and dynamics
Between its closest point (0.835 AU) and its farthest (1.847 AU), the heliocentric distance changes by 1.012 AU over every revolution.
One full revolution takes 1.55 yr (567 days), computed from the semi-major axis of 1.341 AU.
An eccentricity of 0.378 makes the orbit moderately elongated.
The orbital plane is tilted 9.63° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 38.3 km/s at perihelion and falls to 17.3 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 = 20.56 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.27 km.
Observation record and orbit quality
Astrometry from 362 individual observations underpins this orbit; the fit leaves an RMS residual of 0.6205 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.
