Large very bright silent orb flew very fast through night sky then dimmed, blinked and disappeared.

Came home from store at 9:30 p.m.  Noticed a very large extremely bright circular object moving from northwest to southeast.  It moved very quickly and steadily.  It had no other lights around it, it was not an airplane, it was silent.  When it had travelled over our house we saw  an airplane flying towards it, the object then seemed to lose brightness and turn almost yellow while getting smaller and flickering a few ties then disappeared.    I could see a small orange light a few times just for a second then nothing.
