2018 RY7
From Wikipedia, the free encyclopedia
False binary
The asteroid's orbit determination is in need of some improvement. It orbits the Sun at a distance of 0.87–1.17 AU once every 374 days (semi-major axis of 1.016 AU). Its orbit has an eccentricity of 0.1470 and an inclination of 13.35° with respect to the ecliptic.[3] It is a member of Apollo dynamical class in both the JPL Small-Body Database and the Minor Planet Center.[1][3] Apollo asteroids are Earth-crossing asteroids.
2018 RY7 is currently trapped in a 3:5 mean motion resonance with Venus and follows an orbit very similar to that of 2017 SN16.[6] This pair of near-Earth objects show the highest observed level of dynamical coherence among the NEO-population.
Physical characteristics
2018 RY7 has an absolute magnitude of 24.4 which gives a calculated mean diameter between 23 and 103 meters for an assumed geometric albedo of 0.60 and 0.03, respectively.[4][5]
