Six planets will be in alignment this weekend, with four of them shining bright in one sweeping view. What to know about the planet parade.

Six of our cosmic neighbors are expected to line up across the night sky tonight, in what has been dubbed a "planetary parade". Throughout much of January and February, Venus, Mars, Jupiter, Saturn, Uranus and Neptune will be visible splayed out in a long arc across the heavens, with Venus, Mars, Jupiter and Saturn being visible to the naked eye.
