Orbit and dynamics
The path is an ellipse reaching 0.549 AU from the Sun at perihelion and 1.036 AU at aphelion, a radial span of 0.487 AU.
Applying Kepler's third law to a = 0.792 AU gives an orbital period of 0.71 yr, or about 258 days.
An eccentricity of 0.307 makes the orbit moderately elongated.
The orbital plane is tilted 19.47° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 46 km/s at perihelion and falls to 24.4 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
Neither a measured diameter nor a reliable absolute magnitude is available for 2013 XH28, so its physical size remains unconstrained.
Observation record and orbit quality
The current orbit solution is based on 14 observations and has a weighted RMS residual of 0.61 arcseconds.
Condition code U = 9 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.
