U fiirso qoraalka hoose ka dibna ka jawaab su'aasha kadib isla luqadda qoraalka:  Marinka: Janus waxaa aqoonsaday Audouin Dollfus 15kii Diseembar 1966 waxaana la siiyay magaca ku meel gaarka ah S/1966 S 2. Markii hore, Jean Texereau wuxuu sawiray Janus Oktoobar 29, 1966 isagoon ogeyn. Bishii Diseembar 18, Richard Walker wuxuu arkay shay ku yaal isla goobta Janus, laakiin booskiisa lama waafajin karo aragtidii hore. Laba iyo toban sano ka dib, Oktoobar 1978, Stephen M. Larson iyo John W. Fountain waxay ogaadeen in indha indheynta 1966 ay ugu fiican yihiin laba shay oo kala duwan (Janus iyo Epimetheus) oo wadaagaya meelo isku mid ah, Walker ayaa hadda lagu tiriyaa helitaanka Epimetheus. Voyager 1 wuxuu xaqiijiyay qaabkan meeraha 1980kii. (Fiiri dayaxa co-orbital si aad u hesho sharaxaad faahfaahsan oo ku saabsan qaabkooda gaarka ah.)  Su'aal: Yaa aqoonsaday Janus 15-kii December, 1966?
