(39240) Elizabethgaskell is an asteroid of the main inner belt that was discovered on September 29, 1973 by the Dutch astronomer couple Cornelis Johannes van Houten and Ingrid van Houten-Groeneveld . The discovery was made during the 2nd Trojan survey, during which Tom Gehrels surveyed field plates recorded with the 120 cm Oschin Schmidt telescope of the Palomar observatory at the University of Leiden , 13 years after the start of the Palomar-Leiden- Surveys .
The orbit data of the asteroid indicate belonging to the Hungaria group . The 9: 2 orbital resonance with the planet Jupiter is characteristic of this group . The namesake for the Hungaria group is the asteroid (434) Hungaria . The solar orbit of (39240) Elizabethgaskell is steeply inclined at more than 21 ° to the ecliptic of the solar system , another characteristic of Hungaria asteroids.
(39240) Elizabethgaskell was named on July 22, 2013 after the 19th century British writer Elizabeth Gaskell, who, according to the dedication of the asteroid name, is best known for her novel Cranford (1853).
