Sun Facts: 9 Facts About The Sun You Probably Didn’t Know

Solar energy – it’s clean, renewable, abundant, infinite and free. In short: it’s pretty awesome!
But what do we really know about the sun? Here are 9 facts worth knowing about the central star in our solar system.
I was most surprised by fact number 7…

Die Sonne ist der zentrale Stern unseres Sonnensystems, the sun is the central star in our solar system
The central star in our solar system


My favourite facts about the sun


fact 1 – energy provider

The amount of energy that the earth receives from the sun within 1 hour exceeds the energy consumed by all of humanity in the span of one year.

fact 2 – shining bright

The sun’s intensity is quite impressive! 1,360 watts of solar radiation fall on an area of 1 square meter on earth.

fact 3 – enormous potential

Solar energy is the most abundant energy resource available. 173,000 terawatts of solar energy is continuously received by earth. This equates to 10,000 times the world’s total energy use.

fact 4 – hot, hot, hot

The sun’s temperature is about 5,500 degrees °C (10,000 degrees F) on the surface and over 15.5 million °C (28 million degrees F) at the core. Lucky we don’t live too close…

fact 5 – speed of light

Light travels at a speed of about 300,000 km (186,000 miles) per second. Sunlight takes just over eight minutes to reach the earth 149.60 million kilometers (92,900,000 miles) away.

fact 6 – looking good

The sun formed 4.6 billion years ago and is currently about halfway through its lifespan.
It doesn’t look a day over 2 billion if you ask me.

fact 7 – it’s big…

Hard to imagine, but you could fit 1.3 million earths into the sun.

fact 8 – …really, really big

The sun accounts for about 99.86% of the total mass of the solar system. No wonder everything revolves around it!

fact 9 – fasten your seatbelt

As passengers on earth, we are carried around the sun at a speed of 107,182 km/h (66,600 mph). Don’t forget to fasten your seatbelt!


I don’t know about you, but I am impressed. If you know any other cool facts about the sun, I would love to hear them!
