(5696) Ibsen is an asteroid of the outer main belt , which was discovered on September 24, 1960 by the Dutch astronomer couple Cornelis Johannes van Houten and Ingrid van Houten-Groeneveld . The discovery came about as part of the Palomar-Leiden survey , during which Tom Gehrels examined field plates recorded at the University of Leiden with the 120 cm Oschin Schmidt telescope of the Palomar observatory .
The mean diameter of the asteroid was calculated to be 10.373 (± 0.204) km and the albedo to be 0.216 (± 0.026).
Mean distance from the Sun ( major semi-axis ), eccentricity and inclination of the orbit plane of the asteroid roughly correspond to the Themis family, a group of asteroids named after (24) Themis .
(5696) Ibsen was named on November 7, 1995 after the Norwegian writer Henrik Ibsen (1828-1906). Ibsen's works by Peer Gynt (1867), Nora or Ein Puppenheim (1897), Gespenster (1881) and Hedda Gabler (1890) were particularly emphasized in the dedication . An impact crater on the southern hemisphere of the planet Mercury was named after Ibsen as early as 1976 : Mercury crater Ibsen .
