Orbit and dynamics

The path is an ellipse reaching 0.578 AU from the Sun at perihelion and 1.035 AU at aphelion, a radial span of 0.457 AU.

Applying Kepler's third law to a = 0.807 AU gives an orbital period of 0.72 yr, or about 265 days.

An eccentricity of 0.283 makes the orbit moderately elongated.

The orbital plane is tilted 6.78° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 44.4 km/s at perihelion and falls to 24.8 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

The measured diameter is 0.19 km, a value from direct size determination rather than from brightness alone.

A geometric albedo of 0.145 points to a comparatively bright, reflective surface.

Observation record and orbit quality

The current orbit solution is based on 496 observations and has a weighted RMS residual of 0.3072 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.
