Comet Encke is currently in the news as there has been a survey of its nucleus and how it is thought to repair its surface -see https://dailygalaxy.com/2026/11/scientists-7-kilometer-secret-inside-comet/ …. and we learn that the comet’s orbit is gradually decreasing, and unlike the cometary theory they are cold and warm at the surface, the nucleus of Encke is warm all the way through. One may wonder what the orbital period was in the early to mid Holocen. Currently, it is just 3.3 years – which is central to the theory as related by Clube and Napier in their two books published in the 1990s, ‘The Cosmic Serpent‘ and ‘The Cosmic Winter‘ – with the latter perhaps associating cosmic winter with the Earth encountering meteor streams shed by Proto Encke.
