Question 1

True or false: The Sun is a solid ball of fire with a surface you could stand on.

Accepted Answer

False. The Sun is a plasma—extremely hot gas—with no solid surface. It’s composed mostly of hydrogen and helium.

Question 2

True or false: One million Earths could fit inside the Sun, but its volume is only about 1.3 million times Earth’s.

Accepted Answer

True. The Sun’s radius is about 109 times Earth’s, so volume scales as radius cubed—roughly 1.3 million Earths.

Question 3

True or false: The Sun is actually white, not yellow, and only looks yellow from Earth due to our atmosphere.

Accepted Answer

True. Sunlight is white in space; Earth’s atmosphere scatters shorter wavelengths, making it appear yellow, orange, or red.

Question 4

True or false: The Sun loses about 4 million tons of mass every second due to nuclear fusion.

Accepted Answer

True. Fusion converts mass into energy; this mass loss is tiny relative to the Sun’s total mass, but it’s constant.

Question 5

True or false: The Sun’s core is cooler than its surface because energy escapes outward.

Accepted Answer

False. The core is about 15 million°C, while the surface is only 5,500°C. Fusion heats the core, and energy radiates outward.

Question 6

True or false: The Sun will eventually explode in a supernova at the end of its life.

Accepted Answer

False. The Sun lacks enough mass for a supernova. It will become a red giant, then a white dwarf, slowly cooling over billions of years.

Question 7

True or false: The Sun makes a constant humming sound due to its internal pressure waves.

Accepted Answer

True. Solar oscillations create low-frequency sound waves, which scientists have detected and converted into audible hums.

Question 8

True or false: Sunspots are cooler regions on the Sun and appear black because they emit no light.

Accepted Answer

False. Sunspots are cooler (around 4,000°C) but still glow—they appear dark only in contrast to the hotter, brighter surrounding surface.
