Three Comets Will Pass by Earth at the Closest Distance in the Last Few Years

Three comets – 41P/Tuttle-Giacobini-Kresák, 45P/Honda-Mrkos-Pajdušáková, and 46P/Wirtanen – will pass by Earth at the closest distance in the last few years during January and February. Actually, the two comets will fly by Earth in early 2017, while the third one will make the closest approach in late 2018.
