Comets Double-Header

Earlier this year, comet Tuttle passed Earth. However, this comet is different from any comet we have ever seen. This comet has two chunks instead of one, and are held together by what seems to be a very thin material. Scientists are unsure at this time how this structure was formed, but they believe it is a form of contact binary. Tuttle could have broken apart before, and somehow the pieces reconnected to each other. I think that could be highly possible due to the fact that one portion is 5.4 km, and the other is 2.4 km.
