Orbit and dynamics

Between its closest point (0.948 AU) and its farthest (1.387 AU), the heliocentric distance changes by 0.439 AU over every revolution.

One full revolution takes 1.26 yr (460 days), computed from the semi-major axis of 1.167 AU.

An eccentricity of 0.188 makes the orbit moderately elongated.

The orbital plane is tilted 10.33° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 33.3 km/s at perihelion and falls to 22.8 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 = 25.2 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.03 km.

Observation record and orbit quality

Astrometry from 13 individual observations underpins this orbit; the fit leaves an RMS residual of 0.1811 arcseconds.

Condition code U = 7 signals a poorly constrained orbit, so its future path should be treated as provisional.

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.
