410088

410088 belongs to the Apollo group of near-Earth asteroids, whose orbits cross the path of Earth; with a semi-major axis of 2.501 AU it takes 3.96 yr to circle the Sun.

Apollo Observations: 1,838

Orbit and dynamics

The path is an ellipse reaching 0.927 AU from the Sun at perihelion and 4.075 AU at aphelion, a radial span of 3.148 AU.

Applying Kepler's third law to a = 2.501 AU gives an orbital period of 3.96 yr, or about 1,445 days.

The high eccentricity (0.629) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

The orbital plane is tilted 8.32° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 39.5 km/s at perihelion and falls to 9 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

The measured diameter is 1.03 km, a value from direct size determination rather than from brightness alone.

Its geometric albedo of 0.095 indicates a very dark, carbonaceous-type surface.

Observation record and orbit quality

The current orbit solution is based on 1,838 observations and has a weighted RMS residual of 0.3048 arcseconds.

Condition code U = 0 means the orbit is very well determined, leaving only a small uncertainty in the future ephemeris.

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.
