Orbit and dynamics
Between its closest point (0.843 AU) and its farthest (321.0 AU), the heliocentric distance changes by 320.1 AU over every revolution.
One full revolution takes 2,041 yr (745,460 days), computed from the semi-major axis of 160.9 AU.
The high eccentricity (0.995) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.
A steep inclination of 52.08° carries it well above and below the ecliptic plane.
By the vis-viva equation its orbital speed rises to 45.8 km/s at perihelion and falls to 0.1 km/s at aphelion.
Because q < 1 AU and Q > 1 AU, this orbit geometrically intersects the region of Earth's orbit.
Its Tisserand parameter with respect to Jupiter is T_J = 0.73, a standard discriminator between asteroidal and cometary dynamics.
Size and surface
Neither a measured diameter nor a reliable absolute magnitude is available for Borrelly-Daniel, so its physical size remains unconstrained.
Observation record and orbit quality
The current orbit solution is based on 160 observations.
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.
