1 million years
It takes energy in the sun’s core about 1 million years to reach the surface.
It’s not yellow
Most photos of the sun depict it as being orange, red, yellow or a combination of the three. In reality, the sun is white. It appears yellow to us because of the blue light in the Earth’s atmosphere.
It’s really bright
Did you know that it’s brighter than 85% of everything else in the entire Milky Way?
It’s not the brightest thing on Earth though
That record belongs to the skybeam at the Luxor Resort and Casino in Las Vegas. At 42.3 billion candela, the Luxor Sky Beam is the strongest beam of light in the world.
It was a monster
At least that’s what they used to think back in the day. One legend said it was a man with 3 eyes and 4 arms that was abandoned by his spouse for being too bright.
It causes revolutions
That’s right, American historians and Russian scientists have connected revolutions to sunspots. Don’t believe us?
The proof is in the pudding
The American Revolution, French Revolution, Paris Commune, and both Russian Revolutions fell near times of maximum solar activity.
Sunspots were a secret
Galileo was the first to notice sunspots but he hid the discovery for fear of being persecuted.
The sun accounts for 44% of the Earth’s tidal energy while the moon accounts for the remainder.
The Sun can make us taller
When the sun and moon are in apogee, or pulling the Earth in the same direction, our bodies our stretched albeit only microscopically.
The same men who discovered the sun’s source of power helped build the atomic bomb.
In India pregnant women are sometimes kept indoors during an eclipse for fear that their babies will be born with cleft lips.
It will make you sneeze
25% of people sneeze when exposed to sunlight.
The Attishoo Syndrome
That sneezing thing we just talked about? Well, it’s a real problem to people like fighter pilots. In fact, it has been dubbed the attishoo syndrome.
Tromso, in the far north of Norway receives the same amount of annual sunlight as the tropics except all within a 10 week period.
It is heavy
Well, technically it’s massive. In fact, it accounts for about 99% of the mass of the entire solar system.
If it weren’t for the sun, then comets wouldn’t leave a trail of icy particles that always point away from the sun. Why away?
It’s a celestial breeze made up of electrons and protons that have escaped from the Sun’s gravity and it is responsible for blowing those comet tails away from the sun.
1.5 million candles
If you cut off a postage stamp sized portion of the sun it would shine with the intensity of 1.5 million candles.
Everyone knows the sun can be yellow and orange but did you know that it can be green? This phenomenon known as green flash is very rare.
A lot of power
Every year the Earth absorbs 94 billion megawatts of energy from the sun. That’s immensely more than the world’s total energy use.
Every second the sun gives off the same amount of energy as 10 billion nuclear bombs.
If all the Sun’s energy were directed at Earth it would take only 3 minutes for it to melt the crust.
The solar wind is fast
Remember that solar wind we talked about? Well it’s no joke. It moves on average about 280 miles per second and takes only 4 days to reach the Earth.
