Orbit and dynamics

The path is an ellipse reaching 1.18 AU from the Sun at perihelion and 5.102 AU at aphelion, a radial span of 3.922 AU.

Applying Kepler's third law to a = 3.141 AU gives an orbital period of 5.57 yr, or about 2,033 days.

The high eccentricity (0.624) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

A steep inclination of 28.76° carries it well above and below the ecliptic plane.

By the vis-viva equation its orbital speed rises to 34.9 km/s at perihelion and falls to 8.1 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 = 18.38 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.75 km.

Observation record and orbit quality

The current orbit solution is based on 153 observations and has a weighted RMS residual of 0.3231 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.
