Orbit and dynamics

The path is an ellipse reaching 0.627 AU from the Sun at perihelion and 1.208 AU at aphelion, a radial span of 0.581 AU.

Applying Kepler's third law to a = 0.917 AU gives an orbital period of 0.88 yr, or about 321 days.

An eccentricity of 0.317 makes the orbit moderately elongated.

The orbital plane is tilted 10.96° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 43.2 km/s at perihelion and falls to 22.4 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 = 23.91 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.06 km.

Observation record and orbit quality

The current orbit solution is based on 25 observations and has a weighted RMS residual of 0.3076 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.
