2023 BO7

2023 BO7 belongs to the Apollo group of near-Earth asteroids, whose orbits cross the path of Earth; with a semi-major axis of 1.314 AU it takes 1.51 yr to circle the Sun.

Orbit and dynamics

The path is an ellipse reaching 0.993 AU from the Sun at perihelion and 1.635 AU at aphelion, a radial span of 0.642 AU.

Applying Kepler's third law to a = 1.314 AU gives an orbital period of 1.51 yr, or about 550 days.

An eccentricity of 0.244 makes the orbit moderately elongated.

The orbital plane is tilted 5.61° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 33.3 km/s at perihelion and falls to 20.2 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 = 27.16 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.01 km.

Observation record and orbit quality

The current orbit solution is based on 19 observations and has a weighted RMS residual of 0.176 arcseconds.

Condition code U = 8 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.
