Orbit and dynamics

The path is an ellipse reaching 0.91 AU from the Sun at perihelion and 1.004 AU at aphelion, a radial span of 0.094 AU.

Applying Kepler's third law to a = 0.957 AU gives an orbital period of 0.94 yr, or about 342 days.

With e = 0.05, the orbit is close to circular.

The orbital plane is tilted 10.59° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 32 km/s at perihelion and falls to 29 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 = 20.79 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.25 km.

Observation record and orbit quality

The current orbit solution is based on 166 observations and has a weighted RMS residual of 0.6465 arcseconds.

Condition code U = 0 means the orbit is very well determined, leaving only a small uncertainty in the future ephemeris.

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.
