Orbit and dynamics
The path is an ellipse reaching 4.287 AU from the Sun at perihelion and -866,600,000,000 AU at aphelion, a radial span of -866,600,000,004 AU.
The high eccentricity (1) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.
A steep inclination of 150.8° carries it well above and below the ecliptic plane.
Size and surface
Neither a measured diameter nor a reliable absolute magnitude is available for Catalina, so its physical size remains unconstrained.
Observation record and orbit quality
The current orbit solution is based on 65 observations and has a weighted RMS residual of 1.0922 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.
