99 free Aquarius trivia questions with answers — science & nature quiz, new questions added Oct 2026.
This Aquarius trivia quiz covers the eleventh sign of the zodiac from three sides. The astrology questions ask about the water-bearer's dates, its air element (not water), traditional ruler Saturn and modern ruler Uranus, fixed modality, opposite sign Leo, positive polarity, its Hindu name Kumbha, and the much-argued Age of Aquarius that the musical Hair sang about. The astronomy questions turn to the constellation: Sadalsuud and Sadalmelik, the Water Jar asterism, the stream that ends at Fomalhaut, the seven planets of TRAPPIST-1, Gliese 876, the Helix and Saturn nebulae, the demoted cluster M73, and the Eta Aquariid meteors shed by Halley's Comet. The mythology runs from the Babylonian Great One with his overflowing vase and the Egyptian jar that flooded the Nile, to Ganymede snatched by Zeus's eagle, the horses given to his father Tros, Hebe the displaced cupbearer, Jupiter's largest moon, the flood survivor Deucalion, King Cecrops, and the Chinese army of stars. Difficulty runs from easy to expert and is shown on every question, so it suits an Aquarius birthday, a pub quiz 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.

Q 01Which symbol stands for Aquarius in horoscopes and on star charts?
Two wavy lines
Two wavy lines. They are usually read as ripples of the water that the figure of Aquarius, Latin for 'water-carrier', pours out across the sky.
Q 02Aquarius is eleventh in the zodiac, which starts each spring with what sign?
Aries
Aries. Astrologers count the signs from the March equinox, the first day of northern spring, so every list of them opens with Aries and reaches Aquarius second to last.
Q 03Despite its name and its jar, Aquarius belongs to which of the four elements?
Air
Air. The four elements repeat through the zodiac in a set order (fire, earth, air, water), so the eleventh sign lands on air, whatever its figure is pouring.
Q 04Aquarius only carries water; which of these signs truly belongs to the water element?
Scorpio
Scorpio. Two other signs share its water element; each element claims every fourth sign, so the trio fall four months apart around the year.
Q 05Which planet is Aquarius's ruler in modern astrology?
Uranus
Uranus. It was unknown as a planet until William Herschel spotted it by telescope in 1781; modern astrologers later moved Aquarius to it from the sign's ancient ruler.
Q 06In astrology, which modality, the quality given to mid-season signs, does Aquarius have?
Fixed
Fixed. The modalities track a sign's place in its season: cardinal signs open one, while fixed signs such as Aquarius hold the settled middle, here midwinter in the north.
Q 07Which sign is opposite Aquarius on the zodiac wheel?
Leo
Leo. The Sun is said to rule Leo, so astrologers call it 'in detriment', at its weakest, while it crosses the opposite sign in the depth of northern winter.
Q 08Under the tropical zodiac the Sun is in Aquarius between roughly which dates?
January 21 to February 19
January 21 to February 19. Calendars differ by a day, and many print January 20 to February 18, because the Sun reaches the sign at a slightly different moment each year.
Q 09While horoscopes place the Sun in Aquarius, it actually spends the first weeks of that season in which constellation?
Capricornus
Capricornus. Earth's slow wobble has slid the constellations about a month out of step with the signs since the zodiac was drawn up, so the Sun only reaches the stars of Aquarius in mid-February.
Q 10Astrologers pair Aquarius with the eleventh house of a birth chart, which governs what part of life?
Friendships and groups
Friendships and groups. The twelve houses are matched to the signs in order, so the eleventh falls to Aquarius; astrologers also read a person's hopes and wishes there.
Q 11Which name does Hindu astrology give Aquarius, a word shared with the world's largest pilgrimage gathering?
Kumbha
Kumbha. The Sanskrit word means 'water pot', which is why India's Kumbh Mela, the pilgrimage where millions bathe in sacred rivers, is the 'festival of the sacred pitcher'.
Q 12Roughly how long does an astrological age, such as the Age of Aquarius, last?
About 2,160 years
About 2,160 years. Earth's axis takes roughly 26,000 years to trace one slow wobble, and astrologers split that circuit into twelve equal ages, one for each constellation of the zodiac.
Q 13Which age does the Age of Aquarius follow, since astrological ages run backwards through the zodiac?
The Age of Pisces
Q 21The ultracool dwarf TRAPPIST-1 made headlines in 2017 for having how many Earth-sized planets?
Seven
Seven. The find made TRAPPIST-1 the most closely studied planetary system beyond our own, and the James Webb Space Telescope is now checking its worlds for atmospheres.
Q 22The telescope that found TRAPPIST-1's planets has a name honouring the monastery beers of which country?
Belgium
Belgium. The University of Liège team bent 'Transiting Planets and Planetesimals Small Telescope' into TRAPPIST as a salute to the country's famous abbey ales.
Q 23In 1998 Gliese 876 in Aquarius became the first of which small, dim, common type of star found with a planet?
Red dwarf
Red dwarf. Its giant planet, found circling a star with a third of the Sun's mass, was then the nearest known beyond the Solar System and a puzzle for theories of how planets form.
The Age of Pisces. Each age is named for the constellation behind the Sun at the March equinox, and that point creeps backwards through the zodiac, out of Pisces and toward Aquarius.
Q 14Which 1967 musical opened with a song declaring 'the dawning of the Age of Aquarius'?
Hair
Hair. The rock musical's opening number helped carry the phrase 'Age of Aquarius' out of astrology books and into everyday speech, where it became shorthand for the hippie era.
Q 15The Sun passes through Aquarius early in the year, hiding its stars; in which season do northern evenings show them best?
Autumn
Autumn. A constellation is washed out by daylight while the Sun crosses it, so the stars of Aquarius return to the evening sky months later and stand highest around October.
Q 16Which ancient scholar's list of 48 constellations includes Aquarius?
Ptolemy
Ptolemy. His Almagest set out 48 star figures that astronomers never dropped: all still appear on today's official sky map, except a giant ship that was later split into three.
Q 17The two brightest stars of Aquarius look modest only because they lie over 500 light-years away; what are they?
Yellow supergiants
Yellow supergiants. Each began as a hot blue star several times the Sun's mass, then swelled and cooled; the brighter now pours out more than 2,000 times the Sun's light.
Q 18Which Apollo mission's lunar module, named Aquarius, served its crew as a lifeboat after an explosion in space?
Apollo 13
Apollo 13. With their command ship crippled, three astronauts lived for about four days in Aquarius, a lander built to keep two men alive for two days on the Moon.
Q 19Old star maps show the stream poured by Aquarius ending at which bright star in the Southern Fish?
Fomalhaut
Fomalhaut. Ancient astronomers counted it twice, as the end of the stream and as the mouth of the fish that drinks it; modern borders give the star to the Southern Fish alone.
Q 20As a zodiac constellation, Aquarius lies along which line, the Sun's yearly path across the sky?
The ecliptic
The ecliptic. It is named for eclipses, which can happen only when the Moon crosses this line; the Moon and planets keep close to it, so they too pass through Aquarius.
Q 24Which nebula in Aquarius, among the nearest of its kind to Earth, has been nicknamed the 'Eye of God'?
The Helix Nebula
The Helix Nebula. Its rings are the outer layers thrown off by a dying Sun-like star and lit by the hot core left behind, so it shows what the Sun itself will one day become.
Q 25Lord Rosse saw handle-like lobes on either side of NGC 7009 in Aquarius and named the nebula after which planet?
Saturn
Saturn. The faint lobes on either side reminded him of the planet's rings; the nebula itself had been discovered by William Herschel in 1782.
Q 26M73 in Aquarius was long listed as a star cluster, but what really links its four stars?
Chance alignment
Chance alignment. Spectra showed that its stars lie at very different distances and move in different directions, so the 'cluster' logged in 1780 is only a pattern as seen from Earth.
Q 27The galaxy NGC 7252 in Aquarius is nicknamed 'Atoms for Peace' after a speech by which US president?
Dwight D. Eisenhower
Dwight D. Eisenhower. His 1953 speech urged peaceful uses of nuclear power, and the name stuck to the galaxy because its looping trails of stars resemble a textbook atom, with electrons circling a nucleus.
Q 28The Eta Aquariid meteors that streak from Aquarius each May are dust shed by which comet?
Halley's Comet
Halley's Comet. Earth crosses its dust trail twice a year, so the same comet also feeds October's Orionids, though the comet itself returns only about every 76 years.
Q 29Aquarius holds three objects catalogued by which French comet hunter?
Charles Messier
Charles Messier. He listed these fuzzy objects only to stop comet hunters like himself wasting time on them, yet the nuisance list became one of the best-known catalogues of sights in the sky.
Q 30The Sun crosses thirteen constellations each year, Aquarius among them; which one has no zodiac sign of its own?
Ophiuchus
Ophiuchus. The Sun spends about eighteen days in the Serpent Bearer each year, more than twice as long as it spends in neighbouring Scorpius, which does have a sign.
