Orbit and dynamics

Between its closest point (0.884 AU) and its farthest (1.334 AU), the heliocentric distance changes by 0.45 AU over every revolution.

One full revolution takes 1.17 yr (427 days), computed from the semi-major axis of 1.109 AU.

An eccentricity of 0.203 makes the orbit moderately elongated.

The orbital plane is tilted 12.92° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 34.7 km/s at perihelion and falls to 23 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 = 20.86 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.24 km.

Observation record and orbit quality

Astrometry from 89 individual observations underpins this orbit; the fit leaves an RMS residual of 0.4533 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.
