There is a hypergiant star about 5,300 light years from Earth which is the largest known sun thus far. NML Cygni is so large you can fit 3.6 billion of our suns into this thing and if it was positioned in the same place, it’s surface would extend further than the orbit of Jupiter.
The magnetic field of our sun will change its polarity sometime in later 2013, an event felt as far as Pluto and beyond.
There is 10,000 times more sunlight (hitting Earth’s surface) than we need to meet 100 percent of the world’s energy needs. Capture 1 part of 10,000 and the Sun powers the entire planet.
The Earth is spinning at about 1,000 MPH while it obits around the Sun, a unimpressive star, at about 67,000 MPH.
The sun’s warming rays travel 93 million miles to reach earth.
