50 free Polaris trivia questions with answers — science & nature quiz, new questions added Aug 2026.
Polaris trivia for stargazers, sailors, science students and anyone who has ever found north by following the Big Dipper's pointer stars. Most of this quiz is about the North Star itself: the yellow supergiant Alpha Ursae Minoris and its two companions, the four-day Cepheid pulse that makes it a rung on the cosmic distance ladder, the roughly 430-light-year distance argued over by Hipparcos, Hubble and Gaia, and the slow wobble of Earth's axis that made Thuban the pole star for the pyramid builders and will hand the job to Vega in 12,000 years. It also covers Polaris in human hands: Pytheas finding no star at the pole, Columbus correcting for its circle, Shakespeare's 'constant as the northern star', lodestar and cynosure, the Underground Railroad's drinking gourd, and the flags of Alaska and Nunavut. And because the name has been borrowed so often, there are questions on the Polaris submarine missile, Canada's Polaris Music Prize, the Minnesota snowmobile maker, Magneto's daughter in the X-Men and SpaceX's Polaris Dawn spacewalk. Questions range from easy to expert, and every answer was checked against a reference page and carries its source.

Q 01In 2008 NASA beamed which Beatles song toward Polaris to mark the agency's 50th anniversary?
Across the Universe
Across the Universe. NASA sent it from a giant dish near Madrid on the 40th anniversary of the song's recording, and Paul McCartney's message to the agency was "Send my love to the aliens."
Q 02What kind of star is Polaris Aa, the main component of the system?
Yellow supergiant
Yellow supergiant. Polaris Aa has used up the hydrogen in its core and swollen to dozens of times the Sun's width, an unstable stage in which the whole star slowly pulses.
Q 03Like Polaris, which nearby star is really a triple system?
Alpha Centauri
Alpha Centauri. To the eye it is one point of light as well, but a telescope splits it in two, and its third member, Proxima, the nearest star to the Sun, is too faint to see unaided.
Q 04Which astronomer discovered Polaris B, the North Star's faint outer companion, around 1780?
William Herschel
William Herschel. He had come to England to work as a musician and built his own telescopes as a hobby; within two years of spotting Polaris B, that hobby led him to the planet Uranus.
Q 05Which space telescope gave astronomers their first direct view of all three stars in the Polaris system?
Hubble
Hubble. Astronomers had long known from the star's motion that an unseen companion hugged Polaris, but the pair sit so close together that no telescope had managed to show it until 2006.
Q 06Polaris is the closest example of which class of pulsating star, used as a 'standard candle'?
Cepheid variable
Cepheid variable. The slower one of these stars pulses, the brighter it truly is, so timing the pulse and comparing it with how bright the star looks tells astronomers how far away it is.
Q 07Who found that brighter stars like Polaris pulse more slowly?
Henrietta Leavitt
Henrietta Leavitt. She found the rule while measuring photographic plates as a Harvard 'computer', and it later let astronomers prove that other galaxies lie far beyond the Milky Way.
Q 08Which astronomer proved in 1911 that Polaris varies in brightness?
Ejnar Hertzsprung
Ejnar Hertzsprung. The flicker had been suspected since 1852, but it is so slight, about a tenth of a magnitude then and far less now, that it took almost sixty years to prove.
Q 09Research reported in the journal Science suggests Polaris has done what since Ptolemy catalogued it?
Brightened about 2.5 times
Brightened about 2.5 times, from the third magnitude Ptolemy recorded to second today. Astronomer Edward Guinan said that, if real, the change is 100 times larger than stellar evolution theory predicts.
Q 10Approximately how far away is Polaris, according to the Gaia mission?
446 light-years
446 light-years, so the light reaching your eye tonight set out in the late 1500s, during the reign of Elizabeth I. The earlier Hipparcos satellite had put the star slightly closer, at about 430 light-years.
Q 11Many people assume the North Star is the night sky's brightest; which star really holds that title?
Sirius
Sirius. The North Star ranks only about 48th in the night sky; its fame comes from holding its place while every other star wheels around it.
Q 12When the Plough sits too low to see, stargazers find Polaris using which constellation on the star's opposite side?
Cassiopeia
Cassiopeia. Its bright W lies on the far side of Polaris from the Plough and both wheel around the star, so when one is down near the horizon the other is riding high.
Q 13In the northern hemisphere, the height of Polaris above the horizon gives a navigator approximately what?
The observer's latitude
Q 21Which abolitionist founded the 1847 anti-slavery newspaper The North Star, named for the star freedom seekers followed?
Frederick Douglass
Frederick Douglass. He launched it in Rochester, New York, after a speaking tour abroad, striking out on his own from his mentor William Lloyd Garrison, whose paper was The Liberator.
Q 22Which explorer calmed a frightened crew by explaining that the pole star, not the compass needle, had moved?
Christopher Columbus
Christopher Columbus. It happened on his first Atlantic crossing in 1492, when Polaris still circled about three and a half degrees from the true pole, enough to show against a compass.
Q 23In which Shakespeare play does the title character call himself 'as constant as the northern star'?
The observer's latitude. Sail the Caribbean at 16 degrees north and Polaris stands 16 degrees above the horizon; reach the North Pole and it is straight overhead.
Q 14Which two stars in the bowl of the Plough are the 'pointers' that lead the eye to Polaris?
Dubhe and Merak
Dubhe and Merak. Run a line from Merak through Dubhe for about five times the gap between them and you reach Polaris at any hour and in any season, because the whole Plough wheels around it.
Q 15Why does the pole star change over time?
Earth's axis wobbles in a 26,000-year precession
Earth's axis wobbles in a 26,000-year precession, like a slowing top, because the Moon and Sun tug on the planet's bulging equator, and the pole it points to sweeps past one star after another.
Q 16Which star in Draco served as the pole star when Egypt's pyramids were being built?
Thuban
Thuban. Faint and easy to overlook today, it once marked the pole more precisely than Polaris ever will, passing within a fraction of a degree of it around 2800 BC.
Q 17Which bright star will be the pole star in roughly 12,000 years?
Vega
Vega. The title of pole star passes from star to star and comes back round: Vega last held it about 14,000 years ago and, as the fifth-brightest star in the night sky, will far outshine Polaris.
Q 18Which Greek explorer reported around 320 BC that no star marked the celestial pole?
Pytheas
Pytheas. He placed the true pole in an empty patch of sky that made a rough square with three nearby stars; in his day Polaris still circled more than ten degrees away.
Q 19Kochab and Pherkad, the two bright stars in the bowl of the Little Bear, are known by what nickname?
The Guardians of the Pole
The Guardians of the Pole. The pair wheel around Polaris every night as if protecting it, and some three thousand years ago the brighter one, Kochab, was the nearest thing the sky had to a North Star.
Q 20Which star is the southern counterpart of Polaris, lying about one degree from the south celestial pole?
Sigma Octantis
Sigma Octantis. At magnitude 5.5 it is barely visible to the naked eye, so southern navigators have always ignored it and found the pole with the Southern Cross instead.
Julius Caesar
Julius Caesar. He makes the boast seconds before the conspirators stab him, and it is an anachronism too: in the real Caesar's day no star stood at the pole.
Q 24The old English word 'lodestar' for Polaris means what?
Guiding star
Guiding star. 'Lode' once meant a way or course, as in lodestone, the 'way-stone' used to make compass needles, and lodestar still names anything a person steers their life by.
Q 25The word 'cynosure' comes from a Greek name for the Little Bear meaning what?
Dog's tail
Dog's tail. The Greeks called the curve of stars ending at Polaris Kynosoura, and because sailors kept their eyes on it to steer, 'cynosure' came to mean anything that draws every gaze.
Q 26In the Hindu Puranas, which devoted young prince did Vishnu reward with a place as the pole star?
Dhruva
Dhruva. Slighted by his father's favourite queen at the age of five, he went into the forest to meditate, and Vishnu rewarded his devotion with a lasting place among the stars.
Q 27In the African-American folk song 'Follow the Drinking Gourd', the drinking gourd stands for what?
The Big Dipper
The Big Dipper. The folklorist who published the song in 1928 said it was a coded map for people escaping slavery, steering them north by the Dipper's stars, though no trace of it from before 1910 has been found.
Q 28Which state's flag, designed by schoolboy Benny Benson in 1927, shows the Plough and Polaris?
Alaska
Alaska. Benson, a boy at a children's home in Seward, won a contest for the territory's schoolchildren, and wrote that the star stood for 'the future state of Alaska, the most northerly in the Union'.
Q 29Which Arctic territory puts Polaris beside an inuksuk on its flag and coat of arms?
Nunavut
Nunavut. The territory calls the star Niqirtsuituq, and on the flag it stands for more than navigation: it also represents the steady leadership of the community's elders.
Q 30The Polynesian Voyaging Society's navigators call Polaris Hokupa'a; which language is the name from?
Hawaiian
Hawaiian. The society's canoe Hokule'a reached Tahiti in 1976 guided by the Micronesian master Mau Piailug, who then taught Hawaiians the nearly lost art of navigating without instruments.
