It was discovered on May 3, 1858 by Horace Parnell Tuttle and rediscovered independently in 1907 and 1951 by Michel Giacobini and Ľubor Kresák . It belongs to the comets of the Jupiter family . The diameter of the core is estimated at 1.4 kilometers. He was last seen well in 2017:
In spring 2017 it passed through the constellations Hercules and Lyra and could be observed from midnight to dawn between 20 and 40 degrees . On May 1, 2017, it passed the spiral galaxy NGC 6585 at a distance of only 2 ' and on May 4, 2017 in the evening at 3 to 4' the star of 4th magnitude Kappa Lyrae .
