(183294)  Langbroek

In August 2008, the Committee on Small Body Nomenclature of the International Astronomical Union (IAU) officially named asteroid 183294 (also known by its provisional designation 2002 TB382):

 (183294)  Langbroek.

The suggestion to do so came from the discoverers of the object: Stefan Kürti (who found it in NEAT archive imagery) and the NEAT program. It is an honour that I cherish.

The naming citation was published in Minor Planet Circular # 63643 and reads as follows:

(183294) Langbroek = 2002 TB382
Discovered 2002 Oct. 9 by NEAT at Palomar.
Marco Langbroek (b. 1970) is a Dutch archaeologist and amateur astronomer whose
main interests lie in meteor astronomy. He is an avid meteor observer, active
within the Dutch Meteor Society. The name was suggested by S. Kürti.

Asteroid (183294) Langbroek was discovered on images taken at Mt. Palomar on 9 October 2002 with the 1.2m Schmidt telescope of the NEAT project. Below is a stack of the three 60 second exposure CCD images, showing the asteroid as three dots on a line (because it moved inbetween each image, which were taken at approximately 20 minute intervals at 09:09:16 UTC, 09:27:39 UTC and 09:47:56 UTC):

Asteroid (183294) Langbroek is a main belt asteroid orbiting between the planets Mars and Jupiter. It has an estimated size of approximately 2.5 kilometer and an orbital period of 5.3 years. It's orbital elements are as follows:

a = 3.0389884 AU q = 2.6886620 AU Q = 3.3893178 AU
e = 0.1152773 omega = 191.21291 deg H = 15.6
i = 6.33452 deg node = 106.05147 deg (epoch 2455400.5)

Below image shows the asteroid on 25 August 2012, and was shot by me 'remotely' using the 61-cm Cassegrain of Sierra Stars Observatory (MPC G68) in Californië, USA. It is an animated GIF of 4 images.
