2005 KJ10

2005 KJ10 belongs to the Apollo group of near-Earth asteroids, whose orbits cross the path of Earth; with a semi-major axis of 1.883 AU it takes 2.58 yr to circle the Sun.

Orbit and dynamics

Between its closest point (0.792 AU) and its farthest (2.974 AU), the heliocentric distance changes by 2.182 AU over every revolution.

One full revolution takes 2.58 yr (944 days), computed from the semi-major axis of 1.883 AU.

The high eccentricity (0.58) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

The orbital plane is tilted 8.17° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 42.1 km/s at perihelion and falls to 11.2 km/s at aphelion.

Because q < 1 AU and Q > 1 AU, this orbit geometrically intersects the region of Earth's orbit.

Size and surface

No direct size measurement is available; from an absolute magnitude of H = 21.71 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.16 km.

Observation record and orbit quality

Astrometry from 79 individual observations underpins this orbit; the fit leaves an RMS residual of 0.5208 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.
