No need to close as duplicate. If it's a poor question, just close as unclear what you're asking. You can point the user to our help resources which indicate that we have strict requirements for such questions.
For reference: This is what the What topics can I ask about page says:
What about that thing in the sky?
Avoid asking questions about unidentified aerial objects unless you are prepared to provide detailed pictures and/or sufficient description to identify the time, location, and characteristics of the sighted object. Specifically, this is not a UFO reporting site, but identifying things in the sky is a part of astronomy. If you must ask about that thing in the sky, be prepared to explain a lot and add additional information requested by commenters, or your question may be closed quickly.
