Do any contemporary poskim discuss the usage of star stickers with regard to the prohibition of depicting celestial bodies (e.g. the glow-in-the-dark ones people put on walls and ceilings)? What if they are affixed without representing a constellation, but such that they do end up recreating an image of a night sky? Is affixing a sticker akin to drawing a star?
Presumably the prohibition in question would be "You shall not make for yourself a carved item or any image which is in the heaven above..." (Exodus 20:4).
- Rambam implies that the prohibition is only in constructing an image in order to worship it. (Sefer Hamitzvos negative commandment #2) Assuming you have no idolatrous intent it ought to be permitted.
שהזהירנו מעשות ע''ז לזולתנו כדי שיעבוד אותה
- Chinuch (neg. 27) seems to say that the matter is a dispute between Rambam (prohibited only to worship) and Ramban (always prohibited).
