Orbit and dynamics

Between its closest point (1.065 AU) and its farthest (1.767 AU), the heliocentric distance changes by 0.702 AU over every revolution.

One full revolution takes 1.68 yr (615 days), computed from the semi-major axis of 1.416 AU.

An eccentricity of 0.248 makes the orbit moderately elongated.

The orbital plane is tilted 11.67° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 32.2 km/s at perihelion and falls to 19.4 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 = 23.01 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.09 km.

Observation record and orbit quality

Astrometry from 66 individual observations underpins this orbit; the fit leaves an RMS residual of 0.5415 arcseconds.

Condition code U = 1 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.
