To see the parade, find a dark place with a clear view of the western horizon at nightfall. Mercury and Saturn will be low in the sky, brushing past each other in the fading glow of the evening sun, which will make the pair difficult to spot. Trace that line of sight higher to find Venus, the most brilliant planet in the sky.

So far the parade has featured six planets: Jupiter, Mars, Neptune, Saturn, Uranus and Venus. Feb. 23-26, they will be joined by a seventh, Mercury, which has just started to crawl above the horizon, before Saturn soon falls away. But again, this really depends on where you live.

Are 7 planets having a rare alignment in our night sky? News of this unusual celestial event has been flooding social media in the last several days. But what will you really be able to see?
