Orbit and dynamics

The path is an ellipse reaching 0.775 AU from the Sun at perihelion and 1.363 AU at aphelion, a radial span of 0.588 AU.

Applying Kepler's third law to a = 1.069 AU gives an orbital period of 1.11 yr, or about 404 days.

An eccentricity of 0.275 makes the orbit moderately elongated.

The orbital plane is tilted 5.91° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 38.2 km/s at perihelion and falls to 21.7 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 = 29.76 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0 km.

Observation record and orbit quality

The current orbit solution is based on 25 observations and has a weighted RMS residual of 0.3133 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.
