Orbit and dynamics

Between its closest point (0.924 AU) and its farthest (1.414 AU), the heliocentric distance changes by 0.49 AU over every revolution.

One full revolution takes 1.26 yr (462 days), computed from the semi-major axis of 1.169 AU.

An eccentricity of 0.209 makes the orbit moderately elongated.

The orbital plane is tilted 7.78° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 34.1 km/s at perihelion and falls to 22.3 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 = 22.43 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.12 km.

Observation record and orbit quality

Astrometry from 86 individual observations underpins this orbit; the fit leaves an RMS residual of 0.4379 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.
