60 free Capricorn trivia questions with answers — science & nature quiz, new questions added Aug 2026.
This Capricorn trivia quiz covers the tenth sign of the zodiac from three sides. The astrology questions ask about the sea goat's dates, Saturn rulership, cardinal earth quality, negative polarity, opposite sign Cancer and the exaltation of Mars. The astronomy questions turn to the smallest zodiac constellation: Deneb Algedi the tail of the goat, the unrelated double Algedi, Dabih and Nashira, the globular cluster M30, the galaxy group HCG 87, and Neptune's discovery beside its brightest star. There is a section on the Tropic of Capricorn too: its latitude, its slow northward creep, and the four countries that lie entirely south of it. The mythology reaches back to the Babylonian goat-fish of the god Ea, then to Amalthea the goat who nursed Zeus and lost the horn that became the cornucopia, and to Pan diving into the Nile to escape Typhon, taking Syrinx's reeds and the word panic with him. Makar Sankranti, the crocodile Makara, the January garnet and a few unusual names from the Caucasus and Polynesia round it out. Difficulty runs from easy to expert and is shown on every question, so the quiz suits a Capricorn birthday, a pub round or an astronomy night. Every answer was checked against a reference page and each question carries its citation. Try our Zodiac, Astrology and Planets quizzes next.
