Orbit and dynamics

The path is an ellipse reaching 1.029 AU from the Sun at perihelion and 1.351 AU at aphelion, a radial span of 0.322 AU.

Applying Kepler's third law to a = 1.19 AU gives an orbital period of 1.30 yr, or about 474 days.

An eccentricity of 0.135 makes the orbit moderately elongated.

The orbital plane is tilted 9.06° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 31.3 km/s at perihelion and falls to 23.8 km/s at aphelion.

Its perihelion lies just outside Earth's orbit, which is why it is classed as Earth-approaching rather than Earth-crossing.

Size and surface

No direct size measurement is available; from an absolute magnitude of H = 25.62 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.03 km.

Observation record and orbit quality

The current orbit solution is based on 33 observations and has a weighted RMS residual of 0.4086 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.
