Orbit and dynamics

Between its closest point (0.635 AU) and its farthest (1.324 AU), the heliocentric distance changes by 0.689 AU over every revolution.

One full revolution takes 0.97 yr (354 days), computed from the semi-major axis of 0.98 AU.

An eccentricity of 0.352 makes the orbit moderately elongated.

The orbital plane is tilted 5.16° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 43.5 km/s at perihelion and falls to 20.8 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 = 27.7 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.01 km.

Observation record and orbit quality

Astrometry from 24 individual observations underpins this orbit; the fit leaves an RMS residual of 0.4697 arcseconds.

Condition code U = 6 indicates a moderately constrained orbit; predictions decades ahead still carry noticeable uncertainty.

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.
