Space Trivia Questions about the Sun

Unique Space Trivia Questions

Since the ancient times, the Sun is the only out of the world element that has been worshipped. The Sun is always full of surprises and interesting facts. There are so many unknown things still buried under the deep layers of the Sun. Here, we have showcased some interesting space trivia questions about the mysterious Sun. Surely, these would quench your thirst.


What is the temperature of the outer body of the Sun?

The Sun is the most important part of the Solar system that occupies 98% of the whole solar system mass. The outer layer of the Sun is called the Photosphere which has a temperature of 6000⁰C or 11,000⁰F.


How many layers are there in the Sun?

There are altogether 6 layers in the Sun. The outermost layer which is called the Corona, next is Chromosphere, the visible surface called Photosphere, the convective zone, radiative zone, and the inner layer which is called the core.


What is the temperature of the core of the Sun?

The core is the hottest part of the Sun mass and the whole Solar system. It is the chamber house of huge pressure. The temperature in the core section can reach more than 27 million degrees Fahrenheit (15 million degrees Celsius).


How many Earths can fit inside the Sun?

This one question would give you a clear idea about the size and the mass of the Sun. Around 1 million Earth can fit inside the Sun. And, yes! The surface area of the Sun is 11, 990 times the Earth.


What is the energy that the core section of the Sun creates?

Nuclear Fusion is the name. It is the energy that is created when 4 Hydrogen Nuclei is combined into one Helium Nucleus. Here is the basic equation that forms the energy.

1H2 + 1H2 à 2H3 + 0n1 + 3.27 MeV


What is the age of the Sun?

It is pretty surprising to know that the Sun has already crossed half of its age. Its age is 4.5 billion years as of now and half of its Hydrogen has already been burned. It is expected that the rest of the Hydrogen would be enough to go around 5 billion years.


What is the distance between the Earth and the Sun?

The Earth follows an Elliptical path around the Sun. So, the distance between them varies a lot. Generally, it lies between 147 to 152 million km.


In which direction the Sun rotates around the Earth?

Unlike the Earth that rotates from East to West, the Sun rotates in the West to East direction.


What are the Sunspots?

Space Trivia Questions about Sun

The Sunspot is a temporary phenomenon which is pretty interesting. It is associated with the Sun’s Photosphere. The Sunspots are zones with reduced surface temperature; it is caused by the concentrations of magnetic field flux which shows convection. These spots usually appear in pair with opposite magnetic polarity.


What are Solar Winds?

Extremely hot charged particles which are called Plasma are ejected from the Corona layer. These solar winds can travel with a speed of 450km/s through the solar system.


How much time the do Sunrays take to reach the surface of the Earth?

The sun rays have a speed of the light. They take 8 minutes 20 seconds to reach the surface of the Earth.


What type of star is the Sun?

Sun is a Yellow Dwarf star. Any star that has 0.84 to 1.15 solar mass and surface temperature that varies between 5,300 to 6,000 K.


What is the shape of the Sun?

The Sun is considered to be almost a perfect sphere. The polar and the equatorial diameters have a difference of 10km which makes anything almost a perfect sphere.


How Aurora Borealis is created?

This is undoubtedly one of the most beautiful phenomena on the Earth surface. Solar winds are responsible for these. These are charged particles that travel through the vacuum place through the galaxy. If the Earth atmosphere comes in between, these charged particles react with the atmospheric particles. These collisions excite the atoms of the atmosphere and eventually, the lights come out.


How does the Sun look like from the Mercury?

Mercury is the smallest and the innermost planet in the Solar system. So, the Sun from the Mercury looks 2.5 times larger than what it looks from the Earth. Isn’t it a hilarious fact?


What is the composition of the Sun?

The Sun is made of gaseous elements. It has 75% Hydrogen, 25% Helium. There are various metals like 0.1% of the mass of the Sun.


How much water is evaporated every day?

Every day, around One Trillion Tons of water, gets evaporated from the water bodies of the earth. The number is mesmerizing and unbelievable in every way.


Why the surface of the Venus is much hotter than the that of Mercury?

Unique Space Trivia Questions about Planets

In spite of the fact that the distance between the Venus and the Sun is twice as much as that of Mercury, yet it is hotter than the Mercury. Venus has a huge cloud of Carbon Dioxide around it which traps most of the rays of the Sun. And, this phenomena makes its temperature rise up to 465⁰C and eventually has made it the hottest planet in the solar system.


After how many years, the Sun reverses its magnetic polarity?

After every 11 years, the magnetic polarity just becomes reversed. So, North Magnetic pole becomes South Magnetic pole and vice versa.


What is the time period of the Sun?

The Solar rotation period is 24.47 days. This is actually sidereal rotation period. If we talk about Synodic rotation, the time period would be 26.24 days.


If a person weighs 190 pounds, what would be the weight of a person on the surface of the Sun?

The gravity of the Sun is 28 times than that of the Earth’s gravity. So, a person who weighs 190 pounds on the Earth surface, would weigh 5320 pounds on the surface of the Sun.


What is the name of the Sun in Japan?

It is called Taiyō in Japanese. And, as we all know that Japan is also called the Land of the Rising Sun.


Who told first that the Earth orbits around the Sun?

Well! It was a wrong theory to propose for sure. The famous Greek philosopher Aristarchus was the first person to propose this.


What are Solar Flares?

Interesting Space Trivia Questions

This is a pretty interesting phenomenon that happens on the surface of the Sun. This is actually the sudden flash of increased brightness that is more visible near to the Sunspots. Powerful flares are often accompanied by a coronal mass ejection.


Who said that “If I had to choose a religion, the sun as the universal giver of life would be my god”?

This is a beautiful statement that was made by the most eminent French Statesman and French Emperor Napoleon Bonaparte.

How many days it would take an airplane to reach the Moon (if it were possible ever)?

Space Trivia Questions Equations

This is the escape velocity of the Earth to reach the moon; and, this is literally impossible for an airplane to cross this threshold level. But ironically, if the example of Boeing 747 is taken into account which has a speed of 400miles/hr. Then, it would take around 1 month for it to reach the surface of the Moon.


Why the sky from the Moon always look black?

Again, the lack of atmosphere on the surface of the Moon is responsible for that. Without the particles, the sun rays never reach the moon.


How is the atmosphere on the Moon?

It is extremely hot and cold at the same time. When the Sun shines, the temperature can reach up to 260⁰F, which is a few more degrees more than the boiling temperature of the water which is 212⁰F. When there are absolutely no sunrays, the temperature becomes as low as -280⁰F.


Only one scientist has visited the Moon, who is that?

Harrison Schmitt was a lunar module pilot on Apollo 17. He was given the responsibility to examine the rocks of different ages in the Sea of Serenity.


How many people watched the Tv coverage of the Moon landing of Apollo 11 on 1969?

Around 600 million people watched the live coverage. The number itself is spectacular. Surprisingly, Australians saw the footage way before the rest of the world.


Where did the Apollo 11 land a Lunar Module on 21st July 1969?

Interesting Space Trivia Questions about Moon Mission

What is the name of the first craft that landed on the Moon?

Russian spacecraft Luna 2 was the first to do that, though it was a crash landing. And, it affected the Moon. Specifically, Luna 9 made the first soft landing. After all these unsuccessful attempts, Apollo 11 was the first to land on the surface of the moon successfully and made a return trip back to earth as well.


What type of rocks are mostly found on the surface of the Moon?

Basalt is the right answer. Most of the basalts were 3.7 billion years old. These are actually black colored igneous rocks.


How the Moon was formed?

There are several theories involved that explain the formation of the Moon. The most popular one is Giant Impact Hypothesis. The early solar system was a violent place. This theory proposes that a body as big as the Mars which is known as Theia collided with our Earth. This event threw vaporized pieces of the planet’s crust to Space. These ejected particles came together due to the gravity. And, this event eventually created the Moon.


How long does the Moon take to revolve around the Earth?

It takes 29 days to revolve around the Earth. The exact answer would be 27.322 days.


What is the core temperature of the Moon?

The temperature varies between 2420 and 2600⁰F. The value is much lower than that of the Earth. It is because of its smaller size.


What is the diameter of the Moon?

It is 3474Km. Our Earth has a diameter of 12,742 Km. So, Moon is almost 1/4th of its size. Moon is not totally a spherical body and thus, there is a difference between the polar and equatorial diameter.


How many American Astronauts have land on the Moon?

So, there are total 12 American Astronauts who have walked on the Moon. The astronauts returned with more than 800 pounds of Moon rocks and dust.


What is the density of the Moon?

The density of Moon is almost 60% of Earth’s density. Its density is 3.34g/cm3.


What would be the weight of a person on the Moon who weighs 120 pounds on the Earth surface?

Space Trivia Questions Problem and Solution

Here, W=120 pounds. And, the mass would be constant in both the cases.

That’s only 19.8 pounds. And, that’s why people feel lightweight on the surface of the Moon.


Does moonquake happen?

Yes! That’s indeed an interesting phenomenon which is caused by Earth’s gravitational pull. It happens near about several kilometers beneath the surface of the moon that causes cracks and ruptures.


Which country once thought to detonate a nuclear bomb on the moon?

Surprisingly, it was the USA during the 1950s. It was a part of the Project A119. It was an era when they wanted to show their strength in the space arena.


Why the tides occur at the Earth’s surface?

Well! It’s all because of the gravitational pull of the Moon. The oceans bulge towards the direction of the Moon. Tides occur two times a day as the earth is rotating.


What is Blue Moon?

It is basically an additional full moon. It is a seasonal phenomenon that occurs every 2.5 years.
