this object was spherical, luminous,slowed down,and fast when it left.

i was taking the back roads home from bow hunting that evening, like i always do , when i come to the bottom of the ridge, up a head of me was this luminous round ball about the size of a basketball came barreling straight down the ridge at me,hovered past me.the next thing i remembered i was standing at the edge of the road and seeing it disapeer.
Witness indicates that the date of the event is approximate.  PD
