Vorobjov

Vorobjov follows a distinctly cometary orbit: an eccentricity of 0.268 carries it from 3.898 AU at perihelion out to 6.754 AU at aphelion.

Orbit and dynamics

The path is an ellipse reaching 3.898 AU from the Sun at perihelion and 6.754 AU at aphelion, a radial span of 2.856 AU.

Applying Kepler's third law to a = 5.326 AU gives an orbital period of 12.3 yr, or about 4,489 days.

An eccentricity of 0.268 makes the orbit moderately elongated.

The orbital plane is tilted 14.81° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 17 km/s at perihelion and falls to 9.8 km/s at aphelion.

Its Tisserand parameter with respect to Jupiter is T_J = 2.86, a standard discriminator between asteroidal and cometary dynamics.

Size and surface

Neither a measured diameter nor a reliable absolute magnitude is available for Vorobjov, so its physical size remains unconstrained.

Observation record and orbit quality

The current orbit solution is based on 1,273 observations and has a weighted RMS residual of 0.5944 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.
