Our physics teacher just asked this question in class. And I'm pretty sure it is possible.Acceleration is given by the formula v-u/t.
But if the sum (v-u) is not zero then acceleration cannot be zero!
Please, I need detailed answers.Just the example won't do.

There is a super bright large light, like that of a star but bigger and much brighter, in the night sky in a Nor-North Westerly Direction about half way between the moon and the horizon, and slightly to the left off centre from the position of the moon. Apologies for those with cloud cover in the way preventing line of sight, but please I don't need people to tell me I'm NOT seeing things, I just want to know what it is.
