Five planets within the solar system will be visible at the same time—it’s really a rare sighting. Just look up at the end of the month. The best day to see the beautiful celestial event will be Tuesday, March 28. The alignment will be visible several days before and after that, too.

Rather than a straight line, the planets will form an arc in the night sky, and stargazers will get the chance to see Mercury, Venus, Mars, Jupiter, and Uranus. Some of them, though, will be more visible than others, and depending on your location, you might need some equipment to catch a glimpse of all five.
Venus will be the easiest one to spot thanks to its brightness and Mercury will also light the way and will be fairly easy to see by the horizon. It will get a little tougher when trying to spot Uranus, which will be much dimmer compared to the other planets and it will be located near Venus nearly all month. Mars will be more visible, and it will appear high in the sky surrounded by a slightly orange hue.
To see this, your best bet in terms of location are dark sites and low-light pollution areas. You can check where the nearest dark site is on this website, while for light pollution conditions, you can take a look at this map.
