2022 BB

2022 BB belongs to the Apollo group of near-Earth asteroids, whose orbits cross the path of Earth; with a semi-major axis of 1.708 AU it takes 2.23 yr to circle the Sun.

Orbit and dynamics

Between its closest point (0.975 AU) and its farthest (2.441 AU), the heliocentric distance changes by 1.466 AU over every revolution.

One full revolution takes 2.23 yr (815 days), computed from the semi-major axis of 1.708 AU.

The high eccentricity (0.429) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

Its inclination of 4.69° keeps it close to the plane of the ecliptic.

By the vis-viva equation its orbital speed rises to 36.1 km/s at perihelion and falls to 14.4 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 = 27.15 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.01 km.

Observation record and orbit quality

Astrometry from 113 individual observations underpins this orbit; the fit leaves an RMS residual of 0.4457 arcseconds.

Condition code U = 6 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.
