Orbit and dynamics

Between its closest point (1.148 AU) and its farthest (2.026 AU), the heliocentric distance changes by 0.878 AU over every revolution.

One full revolution takes 2.00 yr (730 days), computed from the semi-major axis of 1.587 AU.

An eccentricity of 0.277 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 31.4 km/s at perihelion and falls to 17.8 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

The measured diameter is 1.96 km, a value from direct size determination rather than from brightness alone.

A geometric albedo of 0.105 points to a comparatively bright, reflective surface.

Observation record and orbit quality

Astrometry from 1,971 individual observations underpins this orbit; the fit leaves an RMS residual of 0.5661 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.
