Orbit and dynamics
Between its closest point (1.228 AU) and its farthest (1.48 AU), the heliocentric distance changes by 0.252 AU over every revolution.
One full revolution takes 1.58 yr (575 days), computed from the semi-major axis of 1.354 AU.
With e = 0.093, the orbit is close to circular.
The orbital plane is tilted 12.86° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 28.1 km/s at perihelion and falls to 23.3 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
No direct size measurement is available; from an absolute magnitude of H = 21.82 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.15 km.
Observation record and orbit quality
Astrometry from 50 individual observations underpins this orbit; the fit leaves an RMS residual of 0.4161 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.
