(709) Fringilla is an asteroid of the main belt that was discovered on February 3, 1911 by the German astronomer Joseph Helffrich in Heidelberg .
By measuring star occultations , its size could be determined at 96.6 km. A well-documented star occultation by Fringilla occurred on March 22, 2006 at approximately 6:10 PM UT . The asteroid covered the star TYC 4912-00045-1 (a star 11th magnitude in the constellation Sextant ) for a maximum of 7.1 seconds. The apparent brightness was reduced by about 2.5 size classes. This occultation could only be observed from the mainland in southern Africa .
The name of the asteroid is derived from the Latin name of the finch bird family (Fringillidae).
