Orbit and dynamics

Between its closest point (0.424 AU) and its farthest (1.006 AU), the heliocentric distance changes by 0.582 AU over every revolution.

One full revolution takes 0.60 yr (221 days), computed from the semi-major axis of 0.715 AU.

The high eccentricity (0.407) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

The orbital plane is tilted 10.56° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 54.3 km/s at perihelion and falls to 22.9 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 = 23.92 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.06 km.

Observation record and orbit quality

Astrometry from 148 individual observations underpins this orbit; the fit leaves an RMS residual of 0.5383 arcseconds.

Condition code U = 1 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.
