Open Binary StarsYour specific task is reference for asteroid classification: c-type, s-type, m-type, and near-earth objects. Open the page, drop your input, get the result — typically under a second.
Your goal is reference for binary star systems: visual, spectroscopic, and eclipsing types. Same approach: paste in, get the result, move on. No account, no upload.
Both tools live in the same category, so the choice depends on the exact subtask. Asteroid Types focuses on reference for asteroid classification: c-type, s-type, m-type, and near-earth objects; Binary Stars focuses on reference for binary star systems: visual, spectroscopic, and eclipsing types. Try whichever description matches your goal more closely — they're both free.
