Will an asteroid pass too close for comfort?

The 449th anniversary of Galileo’s birth back in 1564 comes up this Friday, February 15th and he is celebrating with an asteroid passing extremely close to the Earth. It will be zooming passed at 17,200 miles away, which is closer than anything else that has come to us in quite some time including our most distant orbiting satellites. Also, today, February 11th, the sun won’t be completely in sync with our clock as it will be 14 minutes behind what we call “Noon”. This is called “sun slow”. The sun won’t be ahead of Noon until November of this year. And Derrick answers a listeners question about how water might have arrived on Earth. All this and more on this week’s Sky Talk.
