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.
The Earth is spinning at about 1,000 MPH while it obits around the Sun, a unimpressive star, at about 67,000 MPH.
It would take a car traveling at 100 mph nearly 30 million years to reach our nearest star.
The sun’s total lifetime as a star capable of maintaining a life-bearing Earth is about 11 billion years. Nearly half that time has passed.
