2026 LS1

2026 LS1 belongs to the Apollo group of near-Earth asteroids, whose orbits cross the path of Earth; with a semi-major axis of 1.346 AU it takes 1.56 yr to circle the Sun.

Orbit and dynamics

The path is an ellipse reaching 0.906 AU from the Sun at perihelion and 1.787 AU at aphelion, a radial span of 0.881 AU.

Applying Kepler's third law to a = 1.346 AU gives an orbital period of 1.56 yr, or about 570 days.

An eccentricity of 0.327 makes the orbit moderately elongated.

Its inclination of 1.46° keeps it close to the plane of the ecliptic.

By the vis-viva equation its orbital speed rises to 36 km/s at perihelion and falls to 18.3 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 = 26.39 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 38 observations and has a weighted RMS residual of 0.1562 arcseconds.

Condition code U = 6 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.
