Orbit and dynamics

The path is an ellipse reaching 1.059 AU from the Sun at perihelion and 1.649 AU at aphelion, a radial span of 0.59 AU.

Applying Kepler's third law to a = 1.354 AU gives an orbital period of 1.58 yr, or about 575 days.

An eccentricity of 0.218 makes the orbit moderately elongated.

The orbital plane is tilted 17.24° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 31.9 km/s at perihelion and falls to 20.5 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 = 22 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.14 km.

Observation record and orbit quality

The current orbit solution is based on 71 observations and has a weighted RMS residual of 0.493 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.
