Ison potrebbe essersi dissolta durante il suo transito ravvicinato al sole. I telescopi spaziali, puntati sulla nostra stella, non segnalano infatti più la presenza di un oggetto astronomico assimilabile ad una cometa integra.
Dall'immagine ripresa da un centro della NASA, l'ente spaziale degli Stati Uniti, si potrebbe peraltro dedurre che il corpo celeste sia stato polverizzato.
La scomparsa di Ison ha mortificato le aspettative degli appassionati di osservazione astronomica. Non si può tuttavia ancora escludere la possibilità che sia sopravvissuta una parte del nucleo.
