A dwarf planet coming within 11 AU of the sun over the next 10 years
This is actually terrifying.<p>That body is on a cometary orbit, and need not be stable long term.  If it&#x27;s chaotically pushed around by the major outer planets it might get sent into an orbit that gets into the inner solar system.  And if something that size hit Earth, it would be game over for life here -- the impact would vaporize much or all of the oceans.<p>Even an impact by something the size of comet Hale-Bopp would destroy all higher life on the planet.<p>The chance of impacts like this may have been underestimated because of anthropic selection -- if any had occurred in the past (say) 1 billion years then we would not be here.
