“(11436) 1969 QR”的意思、由来-开放百科全书

The S-type asteroid is a member of the Flora family, one of the largest groups of stony asteroids in the main-belt. It orbits the Sun at a distance of 1.9–2.5 AU once every 3 years and 4 months (1,212 days). Its orbit has an eccentricity of 0.14 and an inclination of 7° with respect to the ecliptic. As no precoveries were taken, the asteroid's observation arc starts with its discovery observation in 1969.^[11]

A rotational lightcurve for this asteroid was published by several Hungarian astronomers in August 2005. The photometric observations gave a rotation period of {{val|2.65}} hours with a brightness variation of 0.27 magnitude ({{small|U=2}}).^[5]

The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.24 – derived from 8 Flora, the largest member and namesake of its orbital family – and calculates a diameter of 3.7 kilometers.^[2]

Numbering and naming

This minor planet was numbered by the Minor Planet Center on 28 September 1999.^[16] As of 2018, it has not been named.^[11]
