2022 JD1

2022 JD1 belongs to the Apollo group of near-Earth asteroids, whose orbits cross the path of Earth; with a semi-major axis of 1.244 AU it takes 1.39 yr to circle the Sun.

Orbit and dynamics

The path is an ellipse reaching 0.883 AU from the Sun at perihelion and 1.605 AU at aphelion, a radial span of 0.722 AU.

Applying Kepler's third law to a = 1.244 AU gives an orbital period of 1.39 yr, or about 507 days.

An eccentricity of 0.29 makes the orbit moderately elongated.

The orbital plane is tilted 14.9° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 36 km/s at perihelion and falls to 19.8 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 = 26.8 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 45 observations and has a weighted RMS residual of 0.5056 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.
