The ancient Chinese recorded not 9 but 10 planets in our solar system. The name of the tenth planet was Keito or Keitu (pronounced kei'tu or "k2").
Ancient Sumerian legend also identifies 10 planets in the solar system. Their roller stamp does not contain information about a planet between what we know as Mercury and our own Earth. Despite it currently being the most visible planet in the heaven's sky, information on Venus appears only after the disappearance of two other planets over 4000 years ago. So, the appearance of the Venus may have been caused by a catastrophic incident recorded in Mesopotamia for the whole world.
An astroid causing planets to veer from their orbit? The two planets coliding with one another or their moon(s)? Or maybe the remenants of the planet Keitu have been confirmed by contemporary astronomers.
Nothing would truly prepare us for a catastrophic event, but we do make a difference on a smaller scale. We can eliminate workplace hazards, anticipate and eliminate conditions which may cause damage to our environment, and be prepared to respond to unforseen events. This approach also applies to proper project planning and management and meeting deadlines. And in today's environment of regulatory oversight, advance preparation is useful and cost effective in anticipation of a governmental agency inspection.
The name Keitu reminds all of us to "be ready... be prepared."
