Constellation Quiz

Set up your quiz

Off-zenith chooses a random midnight date and latitude, then an unused constellation whose entire region stays at least 10° above the horizon.

Select any combination of tests, or leave all tests off for practice. Values you aren’t testing are shown. Date and latitude tests require the circular map.

Month input accepts 1–12 or a month name. Typed latitude accepts answers within ±5° of the exact latitude. Multiple-choice latitude uses 10° intervals. Each correct unknown earns one point.
