DETROIT – If the weather cooperates, something very special will be visible on the winter solstice this Monday night -- the “Star of Bethlehem,” also known as the “Christmas Star.”Despite the names, it’s actually not a star at all. Since Jupiter orbits the sun every 12 years and Saturn orbits the sun every 30 years, the two largest planets in the solar system don’t line up very often. The two gas giants will cross paths in the night sky on the winter solstice on Monday, Dec. 21. Though the planets are 450 million miles apart, to the naked eye, they will appear as one bright light in the sky. To view the Christmas Star, turn your gaze toward the southwest sky a little after sunset on Monday, Dec. 21.
