Glowing orange inverted teardrop silently flying low overhead

I was taking my dog out and looked up to see an orange light approaching from the north. Moving slowly and silently, it passed over me at a relatively low altitude.  As it got closer I was able to make out an inverted teardrop shape with a glowing orange core that looked like fire. 
After passing overhead it briefly paused and hovered for 5-10 seconds before progressing further south. 
 I watched as it made its way out of sight with my roommate whom I called to come witness the event.  In all I could see it for about a minute.
