Most of us played astronaut when we were kids, but for some, the fascination about the big, beautiful expanse of space never left us. We look up at the stars with a sense of adventure and wonder what truly is out there beyond our gaze!

If you have always dreamt of visiting a galaxy far, far away, this space trivia quiz is right up your alley. With questions about our solar system and a few about what lies beyond, we delve deep into the darkest corners of space to test you on whether or not you have the scientific know-how. If you know that the Big Bang Theory is more than just a hit television show and you can tell the difference between a nebula and an asteroid, we challenge you to test your space trivia mettle against these 40 questions.

So let's get down to it! If your knowledge is on-point and truly out of this world, you should have no problem navigating through these brain twisters like an expertly piloted spacecraft through a massive asteroid belt. It's time to see who truly paid attention in high school science class with the supernova of all space trivia quizzes.

This object is a huge chunk of rock in belt with other huge chunks of rock. What is it?

Millions of these huge asteroids litter the vast expanse of space. Although they are giant, they are not considered planets, although the larger ones are sometimes called "planetoids."


How old is the sun?

Our amazing sun is 4.5 billion years old, give or take a year. This massive star has been around for a long time, and we would be completely lost (and dead) without its warming light.


Good morning! What direction do you look in to catch a beautiful sunrise?

If you want to catch an amazing sunrise, you will have to look to the east! The sun rises in the east and makes its way across our sky over the course of the day, finally setting in the west.

Which planet is the largest in our universe?

Jupiter is an absolutely enormous planet. It is twice the size of all other planets in our solar system combined and has 318 more mass than Earth. This giant is the fifth planet from the sun.


Some of the stars we see in the night sky no longer exist. How is this possible?

This might be a tough one for some people to wrap their minds around, but many of the stars that we gaze up at no longer exist. This is because light takes time to travel, and the stars are so far away.


We know it as "The Red Planet." Which planet are we talking about?

Mars is nicknamed "The Red Planet" because the iron oxide that dusts its surface gives it the unmistakable red hue that makes it stand out in the sky. There is also a blockbuster movie called "The Red Planet."


We call it the study of space. What is the proper term for it?

Astronomy mixes together some of the most important scientific practices like math, chemistry and physics to study what is going on in the outer space that surrounds our home planet.


What planet is also known as "The Morning Star"?

Venus is known as "The Morning Star" because it rises just a few hours ahead of the sun and fades away as the day begins. Ancient seafarers used Venus as a way to navigate their ships.

No time to turn back now! What is the point of no return around a black hole called?

The Event Horizon is the absolute last place that you can turn back before getting sucked into a black hole with no escape, but we would advise that you not even get that close to one!


What is the gravitational curved trajectory of an object?

An orbit is a path that one celestial body makes around another celestial body because of gravitational pull. Our Earth orbits the sun, and our moon orbits us, making the journey in roughly one month.


Without it, we would all fly off into space. What is it?

Gravity is essentially what keeps all objects where they are supposed to be in our universe. The gravity of our planet Earth keeps us from flying off into space, as the Earth attracts us to it.

Orion's Belt is a constellation that is made up of three brilliant stars: Alnilam, Mintaka and Alnitak. It is easily visible in the sky and has been traditionally used for navigation.


Stars are born from these giant clouds of gas and dust. What are they?

Nebulas are brilliant clouds of gas and dust that drift around in the sky and act as the birthplace for new stars. They are often very far away from our planet and can only be faintly seen.


Which planet famously has a “Great Red Spot”?

The giant of our galaxy is also home to the "Great Red Spot." Jupiter's trademark spot is likely the case of an anticyclonic storm that wages on the planet due to very high pressure.


This planet is named after a Roman god of the sea. What is it?

The ice giant Neptune is named after the Roman god of the sea. It is so far away from Earth, that it is the only other planet in our universe that can't be seen with the naked eye.


They were rivals in the space race, but instead of "astronauts," Russians call their space explorers what term?

The Russian term for "astronaut" is "cosmonaut." The most famous Russian cosmonaut is Yuri Alekseyevich Gagarin, the first person to go into space. There have been several notable cosmonauts since then. Shown here is Valentina Tereshkova, the first woman in space.


This planet gets nice and toasty because it's closest to the sun. What is it?

Mercury is the smallest planet in our universe, and also the closest to the sun. Although Mercury is closest to the sun, it's not as hot as Venus because its atmosphere is different.


Ah, home, sweet home! What is Earth's nickname?

Earth is known as "The Blue Planet" because, when seen from space, it appears to be greenish-blue. This is because Earth is mostly covered in water, which appears blue from outer space.

Stephen Hawking was a theoretical physicist who penned a number of brilliant books and theories about black holes. He was one of the most influential scientists the world has ever seen.


We listed four planets below. Which one does NOT have rings?

Tiny Mercury does not have any rings. It also does not have a moon. It is theorized that any moon or rings would be pulled into the sun since Mercury is so close to that giant star. Shown here is an image of Saturn and its rings taken by NASA's Hubble Space Telescope.


Look up in the sky. What zodiac constellation is shaped like a lion?

Leo is one of the first constellations that was ever discovered and also represents the zodiac Leo sign, a fire sign that represents people born between July 23rd and August 22nd.


Do stars burn forever?

Stars do not burn forever and all of them, including our own sun, will eventually run their course and burn out. When larger stars finally do die they can collapse and form black holes.


Our solar system exists within a galaxy. What is it?

Our galaxy exists within the massive Milky Way Galaxy, a huge spiral-shaped galaxy that is one of many in the overall universe. Our whole galaxy has not been fully mapped because it's so massive.


What former planet was recently demoted?

Poor Pluto! This tiny planet used to be the ninth in the solar system, but it has since been demoted to a dwarf planet. It happened because the International Astronomical Union changed the qualifications for planethood.
