Also called "the civilisation destroyer" The comet Encke is a 4,8 km large piece of space debree that has terrified and scared the hell out of us humans many many times past 20-30 000 years. Its dying, breaking a part, in its last chapter, leaving behind a huge amount of space debree. It has an unusual orbit and uses about 3,3 years around the sun. It also leaves a debreefield behind, that earth crosses twice a year, called northern and southern Taurids. Close approaches to Earth usually occur every 33 years. Normally it just gives us "halloween fireballs", a pretty colour meteor rain show. But sometimes, very rarely, earth comes right behind its tale, or crosses a part of the debreefield with the larger rocks. This is defintive not good and can cause major dicasters and events here on earth. Very rarely we travel trough the most densest of the densest debrefield and earth get really hammered with large ones, which can lead to climate change and hunger, therefor " civilisation killer". According to the scientist there are two (possibly overlapping) peaks separated by a few centuries, every 3000 years. Next one is 3 000 AD.
The Chineese, Han dynasty, and many other sivilisations began studying the comet Encke using and using the sign Swastica around the same time. It is thought because of it looks like one , when it does a near flyby, with its curved jets. Some claim stonehenge was built to follow our greatest threath, the deadly comet Encke, on its journey, and predict when the next two big one is coming, and act as a warning for the next generations to come. It would, if true, certainly be noble and usefull cause.
On june 30, 1908 a major event happened in the tunguska region of Sibir, Russia. Something exploded with the force of 10-20 Megatonn Nuclear bomb in the middle of the forest. A large space fragment was, and still is the hottests theory, but not a single piece of it has been confirmed yet, 100 years later yet. Hundreds of alternative theories has been developed to explain the mystery, but no one has so far delivered the 100% confirmed evidence needed for everyone to agree. So the hunt is still on.
Astronomer Ľubor Kresák suggested in 1978 that the body was a fragment of the short-period Comet Encke, which is responsible for the Beta Taurid meteor shower: the Tunguska event coincided with a peak in that shower, and the approximate trajectory of the Tunguska impactor is consistent with what would be expected from such a fragment. It is now known that bodies of this kind explode at frequent intervals tens to hundreds of kilometres above ground. Ľubor Kresák sadly died in 1994. Astronomers Duncan Steel and Bill Napier also suggest the Beta Taurids could be the cause of the Tunguska event.
