2022 AX
2022 AX is an Aten-type near-Earth asteroid whose orbit lies mostly inside that of Earth, with a semi-major axis of 0.913 AU and a period of 0.87 yr.
Orbit and dynamics
The path is an ellipse reaching 0.655 AU from the Sun at perihelion and 1.172 AU at aphelion, a radial span of 0.517 AU.
Applying Kepler's third law to a = 0.913 AU gives an orbital period of 0.87 yr, or about 319 days.
An eccentricity of 0.283 makes the orbit moderately elongated.
Its inclination of 1.99° keeps it close to the plane of the ecliptic.
By the vis-viva equation its orbital speed rises to 41.7 km/s at perihelion and falls to 23.3 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 = 26.77 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.02 km.
Observation record and orbit quality
The current orbit solution is based on 22 observations and has a weighted RMS residual of 0.3161 arcseconds.
Condition code U = 7 signals a poorly constrained orbit, so its future path should be treated as provisional.
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.
