49 free Leo trivia questions with answers — science & nature quiz, new questions added Oct 2026.
This Leo trivia quiz covers the fifth sign of the zodiac from three sides. The astrology questions ask about the lion's dates, its Sun rulership, fire element and fixed modality, its opposite sign and its polarity, and where the Sun really sits when horoscopes say Leo. The astronomy questions turn to the constellation: Regulus the little king that the Moon keeps hiding, Denebola on the tail, the Sickle asterism, the nearby flare star Wolf 359, R Leonis, Caffau's ancient star, the Leo Triplet of galaxies, the Leo Ring, and the Leonid meteor storms that made 1833 a night nobody in America forgot. The mythology is Heracles' first labour: the invulnerable Nemean lion, the blocked cave, the strangling, the claw that skinned it and the king who hid in a bronze jar afterwards. There are also questions on the Babylonian Great Lion, the Egyptian Knem and the Nile flood, Tutankhamun's throne, and the epithets Ovid and Manilius gave the constellation. Difficulty runs from easy to expert and is shown on each question, so the quiz works for a Leo birthday, a pub round or a stargazing night. Every answer was checked against a reference page and each question carries its citation. Try our Zodiac, Astrology and Planets quizzes for more.

Q 01In traditional astrology, Leo is said to govern which organ of the body?
The heart
The heart. Medieval doctors read the body sign by sign, from the head down to the feet, and the constellation's brightest star had long been called the Heart of the Lion.
Q 02Leo is which sign in the order of the zodiac?
5th
5th. Astrologers pair each sign with the house of the same number, which ties Leo to the fifth house, the one that governs children, play and pleasure.
Q 03Which celestial body is the traditional ruler of Leo?
The Sun
The Sun. Astrologers gave it the sign it crossed in the hottest weeks of the northern summer, while each of the five visible planets had to share its rule across two signs.
Q 04Leo belongs to which classical element?
Fire
Fire. Leo, Aries and Sagittarius sit four signs apart, so the three fire signs mark out a triangle on the zodiac wheel, which is why astrologers call each element's group a triplicity.
Q 05What is Leo's modality in astrology?
Fixed
Fixed. A fixed sign holds the middle of a season, when the weather that began a month earlier has taken firm hold, and Leo sits in the middle of the northern summer.
Q 06Which sign sits opposite Leo on the zodiac wheel?
Aquarius
Aquarius. The water-bearer sits six signs away, directly across the wheel, and astrologers gave that far side to Saturn, the most distant and coldest planet they knew.
Q 07Someone born on which of these dates is a Leo?
August 8
August 8. The sign runs from about July 23 to August 22, yet by the sky's own boundaries the lion's season would not begin until around August 10, because the sky has drifted since the signs were set.
Q 08The sign Leo and the constellation Leo no longer line up because of which slow motion of the Earth?
Its wobbling axis
Its wobbling axis. Called precession, the wobble takes about 26,000 years a turn and has slid the constellations almost a whole sign past the dates astrologers set some 2,000 years ago.
Q 09Which two constellations flank Leo in the zodiac?
Cancer and Virgo
Cancer and Virgo. The zodiac runs eastward through the faint crab, then the lion, then the maiden, so a planet on its usual course enters Leo from Cancer's side and leaves towards Virgo.
Q 10Which asterism, shaped like a backwards question mark, traces the head and mane of Leo?
The Sickle
The Sickle. Six stars curve up from the bright dot at the lion's chest, and the Leonid meteors seem to fan out from inside the blade, which is how the shower got its name.
Q 11Which is the brightest star in Leo?
Regulus
Regulus. The star spins once in about 16 hours, so fast that it bulges at the equator into a squashed egg shape roughly a third wider than it is tall.
Q 12What does the Latin name of Leo's brightest star, Alpha Leonis, mean?
Little king
Little king. The Latin shrinks rex, king, and is no Roman relic: astronomers only gave it to the star in the 1500s, translating its far older Greek name, Basiliskos.
Q 13Alpha Leonis lies so close to the ecliptic that which body regularly passes directly in front of it?
The Moon
The Moon. No other bright star sits so squarely on the ecliptic, so in some years the Moon covers it month after month; a run of 20 such occultations began in July 2025.
Q 21R Leonis in Leo belongs to a class of pulsing red giants named after which star, 'the wonderful'?
Mira
Mira. Astronomers called it wonderful because it fades from plain sight and comes back, and R Leonis does the same every 310 days or so, dipping to telescope-only brightness.
Q 22Caffau's star in Leo, about 13 billion years old, startled astronomers in 2011 by containing almost none of what?
Heavy elements
Heavy elements. Everything in it beyond hydrogen and helium comes to less than a 20,000th of the Sun's share, a sign it formed before earlier stars had forged much; in 2011 no star known was more primitive.
Q 23The Leo Triplet is a group of what?
Galaxies
Q 14Which planet passed directly in front of Alpha Leonis in 1959 and will next do so in 2044?
Venus
Venus. Planets drift past this star all the time but almost never cross it: the 1959 passage was the last by any planet, and the next, on 1 October 2044, will be Venus again.
Q 15Leo's dates fall in July and August, but its constellation is best seen on evenings in which northern season?
Spring
Spring. In high summer Leo is up only by day, lost in the glare, so the lion rules the evening sky months earlier, standing highest around 10 p.m. in early April.
Q 16Which star marks the lion's tail, its Arabic-derived name meaning exactly that?
Denebola
Denebola. The name shortens the Arabic dhanab al-asad, the lion's tail, and Deneb in Cygnus is the same word: it marks the tail of the swan.
Q 17Which astronomer of Alexandria listed Leo among the 48 constellations of his Almagest?
Ptolemy
Ptolemy. His second-century catalogue described the lion star by star, with its brightest in the chest, and Leo is still drawn that way as one of today's 88 official constellations.
Q 18Which space telescope found methane and carbon dioxide in the air of K2-18 b, a planet in Leo?
Webb
Webb. The planet circles a red dwarf 120 light-years away in the zone where water could stay liquid, so a 2025 claim that the James Webb telescope had also sniffed a gas made by life drew headlines and doubt.
Q 19Wolf 359, a faint red dwarf in Leo, is the site of a famous battle in which fictional universe?
Star Trek
Star Trek. In The Next Generation a Starfleet armada gathers at the star to stop a single Borg cube and is wiped out, and Deep Space Nine later opens in the middle of the same battle.
Q 20What powers the sudden flares of Wolf 359, a faint red dwarf in Leo?
Magnetic energy
Magnetic energy. The whole star churns like a boiling pot, winding up a powerful magnetic field, and when that stored energy lets go the dim red dwarf brightens sharply for a few minutes.
Galaxies. M65, M66 and NGC 3628 are three spirals about 35 million light-years away, packed so close that their gravity has pulled one another's shapes out of true.
Q 24The Leo Ring, a vast intergalactic cloud in the constellation, is made of what?
Hydrogen and helium gas
Hydrogen and helium gas. Radio astronomers found the 650,000-light-year ring in 1983 and took it for untouched primordial gas, until 2010 images showed young stars in it and traced the gas to a cosmic collision a billion years ago.
Q 25NGC 2903, a bright barred spiral galaxy in Leo, was discovered in 1784 by which astronomer?
William Herschel
William Herschel. He wrote it down as two nebulae, and the second, later numbered NGC 2905, turned out to be nothing more than a bright knot in one of the galaxy's own spiral arms.
Q 26In 2013 astronomers announced a structure in Leo four billion light-years long, then the largest known, made of dozens of what?
Quasars
Quasars. The Huge Large Quasar Group looked too big for a universe that should be smooth on large scales, but a still larger structure was soon reported, and critics argue the group is a chance pattern.
Q 27Which group of stars was cut away from the tuft of the lion's tail to form a separate constellation?
Coma Berenices
Coma Berenices. The name means Berenice's Hair: an Egyptian queen vowed her hair for her husband's safe return from war, and the astronomer Conon declared that her shorn locks had joined the stars.
Q 28The Leonid meteor shower is associated with which comet?
Tempel–Tuttle
Tempel–Tuttle. The comet orbits in the opposite direction to Earth, so its dust meets our atmosphere almost head-on at about 70 km a second, which makes the Leonids the fastest of the yearly showers.
Q 29Roughly how often do the Leonids produce a full meteor storm?
Every 33 years
Every 33 years. That is how long the parent comet takes to complete one orbit, and the fresh dust near it can turn a shower into a storm: in 1966 meteors fell by the thousand each minute.
Q 30The 1833 Leonid storm led Denison Olmsted to argue that meteors come from where?
A cloud of particles in space
A cloud of particles in space. Olmsted saw that every streak fanned out from one point in Leo and that Europe saw nothing, so it could not be weather; meteor science is dated from his study.
