Think you know the Sun? A surprisingly tricky trivia quiz about it! (1–10)
What is the approximate surface temperature of the Sun in degrees Celsius?
- 1,500℃
- 5,500℃
- 15,000℃
See the answer
Option 2
The surface temperature of the Sun is estimated to be about 5,500°C. This value is calculated based on the assumption that the Sun emits blackbody radiation and refers to the temperature of the outermost layer called the photosphere. The core of the Sun is much hotter, estimated to reach around 16 million°C.
How much time has passed since the Sun was born?
- about 4.6 million years
- about 4.6 billion years
- About 46 billion years
See the answer
about 4.6 billion years
The solar system and the Sun were formed about 4.6 billion years ago. This estimate is inferred from data collected from the Sun and nearby celestial bodies, as well as theoretical insights into star and planet formation. Therefore, the correct answer is “about 4.6 billion years.”
What is happening at the center of the Sun?
- chemical reaction
- nuclear fusion reaction
- atomic decay
See the answer
nuclear fusion reaction
What occurs at the Sun’s core is nuclear fusion. In this process, hydrogen nuclei (protons) fuse under extremely high temperatures and pressures to form helium nuclei. Enormous amounts of energy are released in the process, which serve as the source of the Sun’s light and heat.
What do we call it when, during a solar eclipse where the Sun is temporarily obscured, it becomes completely covered?
- partial solar eclipse
- total solar eclipse
- annular solar eclipse
See the answer
total solar eclipse
There are different types of solar eclipses, such as partial, total, and annular. When the Moon completely covers the Sun, it is called a total solar eclipse. An annular solar eclipse refers to a situation where the Moon appears slightly smaller, so only the outer edge of the Sun is visible and it is not completely covered.
How does the temperature of the sunspots visible on the Sun’s surface compare to the surrounding areas?
- lower than the surroundings
- The same as others around me
- higher than the surroundings
See the answer
lower than the surroundings
The surface temperature of the Sun is about 5,500 K, while sunspots are about 3,500–4,500 K. This means they are roughly 1,500 K cooler than their surroundings. Sunspots appear darker than the surrounding areas because this temperature difference causes them to emit less light.
