(192642) 1999 RD32
, provisionally known as 1999 RD32, is a near-Earth asteroid and potentially hazardous object.〔 It was discovered on 8 September 1999 by Lincoln Near-Earth Asteroid Research (LINEAR) at an apparent magnitude of 18 using a reflecting telescope.〔
With two precovery images from January 1995,〔 the asteroid has a very well determined orbit with an observation arc of 17 years.〔 It is known that passed from Earth on 27 August 1969.〔 During the 1969 close approach the asteroid reached about apparent magnitude 8.8.〔 The similarly-sized 4179 Toutatis also reached that brightness in September 2004. passed less than from asteroid 29 Amphitrite on 17 January 1939.〔
Arecibo radar observations on 5–6 March 2012 showed that is approximately in diameter〔 and has an albedo of only a few percent.〔 The two visible lobes suggest that is a tight binary asteroid or contact binary.〔 About 10–15% of near-Earth asteroids larger than 200 meters are expected to be contact binary asteroids with two lobes in mutual contact.〔
