2018 BF3
Description. orbits the Sun at a distance of 0.8–2.3 AU once every 23 months (706 days; semi-major axis of 1.55 AU). Its orbit has an eccentricity of 0.48 and an inclination of 12° with respect to the ecliptic. With an aphelion of 2.3 AU, it is a Mars-crosser, crossing the orbit of the Red Planet at 1.666 AU. It is also an Earth-crosser, as are all Apollo asteroids. The body's observation arc begins at Mount Lemmon with its first observation on 20 February 2018. 2018 flyby. On 19 January 2018, the object passed  at a nominal distance of only from Earth. This corresponds to 0.63 LD. Close approaches are projected for 28 October 2019 and 26 August 2021, both at a much larger distance (0.24 AU). Physical characteristics. The Minor Planet Center estimates a diameter of , concurring with other estimates of . As of 2018, no rotational lightcurve of this object has been obtained from photometric observations. The asteroids's rotation period, pole and shape remain unknown. Numbering and naming. This minor planet has not yet been numbered.
