It was discovered on 17 April 1968, by Swiss astronomer Paul Wild at the Zimmerwald Observatory near Bern, Switzerland.
[3] In April 2007, a rotational lightcurve of Pogson was obtained from photometric observations by an international collaboration of Australian, European and American astronomers, namely, David Higgins , Petr Pravec, Peter Kušnirák, Julian Oey and Donald Pray.
[12] Additional period determinations were made by Melissa Dykhuis and collaborators (2.5698 h) at the Calvin College Observatory (H62) during 2008 (U=2+),[16] and by Pierre Antonini (2.5699 h) and Julian Oey (2.604 h) in March 2013 (U=3-/2).
[17][18] During the photometric observation in 2007, it was also revealed, that Pogson is an asynchronous binary system with a minor-planet moon in its orbit.
[8][9][10][11] The Collaborative Asteroid Lightcurve Link adopts the result from Petr Pravec's revised WISE-data,[11] that is, an albedo of 0.2188 and a diameter of 8.35 kilometers based on an absolute magnitude of 12.659.
