Groeller

Groeller follows a distinctly cometary orbit: an eccentricity of 0.373 carries it from 2.417 AU at perihelion out to 5.29 AU at aphelion.

Orbit and dynamics

The path is an ellipse reaching 2.417 AU from the Sun at perihelion and 5.29 AU at aphelion, a radial span of 2.873 AU.

Applying Kepler's third law to a = 3.853 AU gives an orbital period of 7.56 yr, or about 2,762 days.

An eccentricity of 0.373 makes the orbit moderately elongated.

The orbital plane is tilted 16.83° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 22.4 km/s at perihelion and falls to 10.3 km/s at aphelion.

Its Tisserand parameter with respect to Jupiter is T_J = 2.88, a standard discriminator between asteroidal and cometary dynamics.

Size and surface

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

Observation record and orbit quality

The current orbit solution is based on 187 observations and has a weighted RMS residual of 0.8245 arcseconds.

Condition code U = 4 indicates a moderately constrained orbit; predictions decades ahead still carry noticeable uncertainty.

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.
