289 Nenetta
Nenetta (minor planet designation: 289 Nenetta) is an A-type asteroid with a diameter of . It was discovered by Auguste Charlois on 10 March 1890 in Nice, France. The asteroid is orbiting the Sun at a distance of  with an eccentricity (ovalness) of 0.204 and an orbital period of . The orbital plane is inclined at an angle of 6.7° to the plane of the ecliptic. Photometric observations taken in 2018 provided a light curve showing a synodic rotation period of  for the asteroid with an amplitude of  in magnitude. This result is mostly consistent with previous measurements. The spectrum of 289 Nenetta reveals the strong presence of the mineral olivine, a relative rarity in the asteroid belt. References
