Solar Science Quiz

Light travels from the Sun to Earth in about 8 minutes and 20 seconds, covering a distance of approximately 150 million kilometers.

The Sun is primarily composed of hydrogen about 74% by mass. Helium makes up about 24%, with trace amounts of other elements.

The Sun generates energy through nuclear fusion, where hydrogen atoms combine to form helium, releasing enormous amounts of energy in the process.

The Sun is classified as a G-type main-sequence star, also known as a yellow dwarf. It is currently in the middle of its life cycle.

A solar flare is a sudden, intense burst of radiation caused by the release of magnetic energy from the Sun’s surface.

The corona is the Sun’s outermost layer, extending millions of kilometers into space and visible during a solar eclipse.

The photosphere is the visible surface of the Sun, where sunlight is emitted.

The Sun is about 4.6 billion years old and is expected to continue shining for another 5 billion years.

The Sun’s diameter is about 1,392,700 km, making it about 109 times wider than Earth.

Sunspots are cooler, darker regions on the Sun’s surface caused by intense magnetic activity
