2025 VR4

2025 VR4 belongs to the Apollo group of near-Earth asteroids, whose orbits cross the path of Earth; with a semi-major axis of 1.141 AU it takes 1.22 yr to circle the Sun.

Orbit and dynamics

The path is an ellipse reaching 0.767 AU from the Sun at perihelion and 1.515 AU at aphelion, a radial span of 0.748 AU.

Applying Kepler's third law to a = 1.141 AU gives an orbital period of 1.22 yr, or about 445 days.

An eccentricity of 0.327 makes the orbit moderately elongated.

Its inclination of 2.38° keeps it close to the plane of the ecliptic.

By the vis-viva equation its orbital speed rises to 39.2 km/s at perihelion and falls to 19.8 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 VR4, so its physical size remains unconstrained.

Observation record and orbit quality

The current orbit solution is based on 20 observations and has a weighted RMS residual of 0.3967 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.
