The objective of Orbient is to control a white star which grows larger by absorbing blue stars and collecting smaller gray stars to form orbiting satellites.
Colliding with these stars will not change the white star's size, but if the player positions the white star just right, the gray star will orbit the white and become a satellite.
"You could call it a heel crack or a quarter-crack," said Jim Ryerson, who trains the gray star.
They have bracts around each flower that have grey star shaped hairs and long black gland tipped hairs.
For the 2006-07 season, the ball had grey stars trimmed in red and white and the Finale Athens ball is a chrome silver metallic with royal blue and white.
Sounds like a great comeback - but it's so frustrating that you persist in using these grey stars against a grey and white background.
But the trainer of the 5-year-old gray star said that he was still not certain the horse would run in the Breeders' Cup.
And when she at last looked up at me her eyes seemed like two grey stars, full of reflections from the golden pool.
Now there were several dozen bobbing below, revolving slowly, solid black balls spotted with gray stars, with no marks or traces of structuring.
Even the faint gray stars high above.
