[Verginius Rufus]

No one 25,000 B.C. could have known about Uranus, Neptune, or Pluto. They probably wouldn't think of earth as a planet.

Maybe the 9 stands for 9 bright objects in the sky--the sun, the moon, Mercury as a morning star, Mercury as an evening star, Venus as a morning star, Venus as an evening star, Mars, Jupiter and Saturn.

Or perhaps the 8 brightest stars in the Big Dipper and Polaris. Ca. 25,000 B.C. Polaris would have been the bright star nearest the north pole.

There are other ancient cultures who had knowledge of planets unseen yet. The dogon, the Sumerians, and they are finding others. So it is not beyond possible.
