Orbit and dynamics
The path is an ellipse reaching 0.771 AU from the Sun at perihelion and 1.004 AU at aphelion, a radial span of 0.233 AU.
Applying Kepler's third law to a = 0.887 AU gives an orbital period of 0.84 yr, or about 305 days.
An eccentricity of 0.131 makes the orbit moderately elongated.
Its inclination of 2.37° keeps it close to the plane of the ecliptic.
By the vis-viva equation its orbital speed rises to 36.1 km/s at perihelion and falls to 27.7 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 2025 DS1, so its physical size remains unconstrained.
Observation record and orbit quality
The current orbit solution is based on 24 observations and has a weighted RMS residual of 0.4223 arcseconds.
Condition code U = 5 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.
