Orbit and dynamics
Between its closest point (1.52 AU) and its farthest (-21,881 AU), the heliocentric distance changes by -21,883 AU over every revolution.
The high eccentricity (1) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.
The orbital plane is tilted 16.99° relative to the ecliptic.
Size and surface
Neither a measured diameter nor a reliable absolute magnitude is available for McNaught, so its physical size remains unconstrained.
Observation record and orbit quality
Astrometry from 1,317 individual observations underpins this orbit; the fit leaves an RMS residual of 0.7074 arcseconds.
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.
