2013 XG10

2013 XG10 belongs to the Apollo group of near-Earth asteroids, whose orbits cross the path of Earth; with a semi-major axis of 1.828 AU it takes 2.47 yr to circle the Sun.

Orbit and dynamics

The path is an ellipse reaching 0.981 AU from the Sun at perihelion and 2.675 AU at aphelion, a radial span of 1.694 AU.

Applying Kepler's third law to a = 1.828 AU gives an orbital period of 2.47 yr, or about 903 days.

The high eccentricity (0.463) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

The orbital plane is tilted 7.36° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 36.4 km/s at perihelion and falls to 13.3 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 = 25.4 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.03 km.

Observation record and orbit quality

The current orbit solution is based on 26 observations and has a weighted RMS residual of 0.3332 arcseconds.

Condition code U = 4 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.
