2015 GE1

2015 GE1 belongs to the Apollo group of near-Earth asteroids, whose orbits cross the path of Earth; with a semi-major axis of 1.731 AU it takes 2.28 yr to circle the Sun.

Orbit and dynamics

The path is an ellipse reaching 0.96 AU from the Sun at perihelion and 2.502 AU at aphelion, a radial span of 1.542 AU.

Applying Kepler's third law to a = 1.731 AU gives an orbital period of 2.28 yr, or about 832 days.

The high eccentricity (0.446) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

The orbital plane is tilted 11.09° relative to the ecliptic.

By the vis-viva equation its orbital speed rises to 36.5 km/s at perihelion and falls to 14 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 = 25.7 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.03 km.

Observation record and orbit quality

The current orbit solution is based on 110 observations and has a weighted RMS residual of 0.3247 arcseconds.

Condition code U = 7 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.
