2026 SP2

2026 SP2 is an Amor-type near-Earth asteroid that approaches Earth from beyond our orbit without crossing it, orbiting the Sun at 1.359 AU once every 1.58 yr.

Orbit and dynamics

The path is an ellipse reaching 1.041 AU from the Sun at perihelion and 1.678 AU at aphelion, a radial span of 0.637 AU.

Applying Kepler's third law to a = 1.359 AU gives an orbital period of 1.58 yr, or about 579 days.

An eccentricity of 0.234 makes the orbit moderately elongated.

The orbital plane is tilted 17.29° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 32.4 km/s at perihelion and falls to 20.1 km/s at aphelion.

Its perihelion lies just outside Earth's orbit, which is why it is classed as Earth-approaching rather than Earth-crossing.

Size and surface

No direct size measurement is available; from an absolute magnitude of H = 26.38 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 20 observations and has a weighted RMS residual of 0.7176 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.
