The discovery was initially credited to Francesco de Vico. Vico, observing from Rome, was the first to report the comet's discovery in Europe. However, Mitchell observed the comet two days before Vico did, so she became recognized as the comet's discoverer.[2][3]

The comet had a weakly hyperbolic orbit solution while inside the planetary region of the Solar System.[1] An orbit solution when the comet is outside of the planetary region shows that the comet is bound to the Sun.

La 1847 T1 Mitchell è una cometa non periodica scoperta il 1º ottobre 1847 dall'allora astrofila, poi astronoma, statunitense Maria Mitchell. La cometa ha presentato una chioma di 30' di diametro, condensata al centro ma senza nucleo apparente[2], in alcune occasioni si è scorta una coda di 2°, a causa della sua declinazione troppo australe è stata persa di vista il 18 ottobre 1847 per poi essere riosservata il 10 dicembre, dopo il suo passaggio al perielio, dagli astronomi in servizio presso l'osservatorio del Collegio Romano[3].
