Saturn, Venus and Mercury, planets will align
The three planets have been forming a triangle for the past few nights, but Monday night they will line up within a tenth of a degree. They'll be visible without the aid of a telescope or binoculars.
Fun Fact: The closest planet to the sun - Mercury - is not the hottest. Venus is. The surface temperature of Venus is 870 degrees Fahrenheit. That's hot enough to melt lead.
