Orbit and dynamics

The path is an ellipse reaching 0.511 AU from the Sun at perihelion and 1.143 AU at aphelion, a radial span of 0.632 AU.

Applying Kepler's third law to a = 0.827 AU gives an orbital period of 0.75 yr, or about 275 days.

An eccentricity of 0.382 makes the orbit moderately elongated.

The orbital plane is tilted 14.38° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 49 km/s at perihelion and falls to 21.9 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 = 24.31 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.05 km.

Observation record and orbit quality

The current orbit solution is based on 21 observations and has a weighted RMS residual of 0.2843 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.
