- 1Which planet is known as the Red Planet?MarsCorrect answerVenusJupiterSaturnMultiple ChoicescienceastronomymarsMars is called the Red Planet due to its reddish appearance.
- 2What is the largest planet in our solar system?JupiterCorrect answerSaturnNeptuneUranusMultiple Choicesciencejupiterplanetssolar-systemJupiter is the largest planet in our solar system.
- 3What is the closest planet to the Sun?MercuryCorrect answerVenusEarthMarsMultiple Choicesciencemercuryplanetssolar-systemMercury is the closest planet to the Sun.

- 5What is the primary reason that Venus is hotter than Mercury, despite Mercury being closer to the Sun?Venus has a thick atmosphere that traps heatCorrect answerVenus is larger than MercuryVenus reflects more sunlight than MercuryMercury has no atmosphereMultiple ChoicevenusastronomyVenus is hotter than Mercury due to its thick atmosphere, which is primarily composed of carbon dioxide. This atmosphere creates a strong greenhouse effect, trapping heat. While it is true that Mercury has no atmosphere, it also does not retain heat well despite being closer to the Sun.
- 6Which of the following statements about dwarf planets is true?They are not able to clear their orbit of other debrisCorrect answerThey orbit the Sun but are larger than MercuryThey are all located in the asteroid beltThey must be spherical in shapeMultiple ChoiceastronomygeneralDwarf planets, such as Pluto, are defined by their inability to clear their orbit of other debris, distinguishing them from the eight major planets. They can vary in size and are not restricted to a specific location in the Solar System.
- 7How do astronomers determine the distance to galaxies using the Tying of Cepheid Variables?By measuring the period-luminosity relationship of Cepheid variablesCorrect answerBy analyzing the redshift of light emitted from galaxiesBy observing the gravitational lensing effects caused by dark matterBy counting the number of stars in the galaxyMultiple ChoiceastronomyThe period-luminosity relationship of Cepheid variables allows astronomers to determine their intrinsic brightness based on the time it takes to complete one cycle of brightness fluctuations. By comparing this intrinsic brightness to the observed brightness, they can calculate the distance to the galaxy. This method is crucial for measuring distances in the universe.
- 8Which of the following statements best explains why most galaxies are found in clusters?Gravitational attraction between galaxies leads to their clusteringCorrect answerGalaxies are formed in isolation and later come togetherGalaxies are attracted to the largest galaxy in the areaGalaxies avoid regions of lower densityMultiple ChoiceastronomyGalaxies are found in clusters primarily due to gravitational attraction. The mass of galaxies creates gravitational fields that pull nearby galaxies toward them, forming clusters over time. This understanding is essential in the study of galaxy formation and large-scale structure in the universe.
- 9Would you rather be a space explorer or a space colonist?space explorerspace colonistThis or Thatwould-you-ratherspaceChoosing to be a space explorer means embracing the thrill of discovery and adventure as you navigate the cosmos, potentially finding new worlds and phenomena. On the other hand, being a space colonist involves the challenge of creating a sustainable life in a new environment, focused on community and survival. Both options offer unique prospects and potential risks.

It arrived at Jupiter in July 1979, followed by a flyby of Saturn in August 1981, then Uranus in January 1986, and finally Neptune in August 1989.
- 15The term "light-year" refers to:A measure of timeA measure of distanceCorrect answerThe speed of lightA measure of brightnessMultiple ChoicespacetermsastronomyscienceA light-year is a unit of distance, representing how far light travels in one year (about 9.46 trillion km).
- 16Voyager 2 has already left the Solar System and entered interstellar space.TrueCorrect answerFalseTrue or Falsespacescienceastronomyvoyager2sunVoyager 2 entered interstellar space on November 5, 2018, making it the second human-made object to leave the Sun's protective bubble, known as the heliosphere.
- 17What’s the name of the Sun’s protective bubble that surrounds our solar system?HeliosphereCorrect answerAsteroid BeltOort CloudExosphereMultiple ChoicespaceastronomysunscienceThe solar wind of our sun creates a protective bubble that surrounds our solar system, called the heliosphere.

What's the name of that gas?HeliumCorrect answerFartArgonMethaneMultiple Choicescienceastronomyfun19th centuryHelium is the lightest noble gas and was first identified during a solar eclipse; it actually gets its name from the Greek word 'helios,' meaning sun.
- 21A day on Venus is longer than a _____ on Venus.yearCorrect answerweekmonthdecadeFill in BlankfunspaceplanetstimeVenus takes 243 Earth days to rotate once but only 225 Earth days to orbit the Sun. So if you lived on Venus, you'd celebrate your birthday before the day ends!
- 22Which planet in our solar system rotates sideways?VenusUranusCorrect answerNeptuneJupiterMultiple ChoicefunspaceplanetsgeneralMost planets spin with their poles pointing almost straight up as they go around the Sun. But Uranus is tilted on its side about 98 degrees. So instead of spinning upright, it moves around the Sun rolling on its side.

The Shannon Number estimates 10^120 possible chess games, while there are "only" about 10^80 atoms in the observable universe.
- 24Which planet could theoretically float in water?MarsSaturnCorrect answerNeptuneJupiterMultiple ChoicefunspaceplanetsscienceSaturn's density is only 0.687 g/cm³, less than water's 1 g/cm³, so it would float! Of course, you'd need an impossibly large ocean, and Saturn would eventually dissolve, but theoretically it works!
- 25The Moon is moving away from Earth at _____ centimeters per year.3.8Correct answer2124.6Fill in BlankfunspacemoonearthastronomyThe Moon drifts 3.8 cm away annually due to tidal forces. In 600 million years, total solar eclipses will be impossible because the Moon will appear too small to cover the Sun completely.
- 26A full moon on Halloween occurs approximately every _____ years.81319Correct answer25Fill in BlankhalloweenastronomymoonFull moons on Halloween occur roughly every 19 years due to the Metonic cycle. The last ones were 2001 and 2020, with the next in 2039. Regional visibility varies.
