A System With Nine, For Real!

See, now.  We (they) should have left Pluto alone.  Now, another planetary system has been found, which boasts NINE planets.  NINE!  We are claiming only eight!

Studies completed by researchers at The University of Hertfordshire, Hatfield, England, have shown solid evidence of a planetary system that contains nine worlds.  This system is located with the host star HD 10180, which is roughly 127 light years away from us.   So, I guess that it is not surprising to find that HD 10180 has numerous planets orbiting it.

This star actually is a G-type main sequence star, glowing yellow, just like The Sun.  The outer surface of HD 10180 is estimated to burn at 5,911 degrees, Kelvin; pretty damned HOT!  Scientists deduce that HD 10180 is roughly 7.3 billion years old.  The star is located within The Hydrus Constellation.

It was while an astronomer from The University of Hertfordshire was studying HD 10180 that the discovery of nine worlds around another star was made.  Astronomer Mikko Tuomi, working at The University of Hertsfordshire, made this find.  It was verified by using The High Accuracy Radial Velocity Planet Searcher (HARPS), which functions with La Silla Paranal Observatory, located within La Region Coquímbo de Chile.

It was during 2010 when initial discovery information about this planetary system was made.  At that time, five planets around HD 10180 were known, and the presence of two more planets was highly likely.  Further studies by Mikko Tuomi went onto verify that eight, then nine planets, indeed existed around HD 10180.

One astronomer from The University of Florida at Gainsville, Eric Ford, suggests that caution need be taken when it comes to verifying the actual existence of nine worlds around this star.  He has stated that further evidence needs to be provided, in order to make true statements about a distant star being the host to nine worlds.  Yet, Ford is not surprised by the results made from these studies by Dr. Tuomi.  He does question, as do several people, about how many planets actually can revolve around a single star!
