Skywatchers have something genuinely special to look forward to this week. On April 16, 2026, a rare planetary alignment will bring Mercury, Mars, Saturn and Neptune together in the early morning sky. It’s not a one-day blink-and-miss event either. The alignment will remain visible for a few days, peaking between April 18 and April 20. If you’re someone who enjoys quiet moments before sunrise, this might be worth waking up early for. Keep reading to find out how and when to catch it.What Exactly Is A Planetary Alignment?Despite how it sounds, the planets aren’t actually lining up in space like beads on a string. Astronomers explain that this is more of a visual trick from our viewpoint on Earth. Since planets orbit the Sun along a similar flat
path, they sometimes appear grouped together in the sky. Think of it as perspective doing its thing rather than a cosmic traffic jam.What You’ll See In The SkyIf you step out before sunrise, here’s how the lineup is expected to appear. Mercury will sit closest to the horizon and may be tricky to spot at first because of the growing daylight. Just above it, Saturn will show up as a dim yellowish point. Mars, thankfully, makes things easier with its distinct reddish glow and higher position. Neptune is the quiet one in this group, faint and invisible to the naked eye, so binoculars or a telescope will be needed.6 Interesting Pictures Captured by The Crew During Artemis IIBest Time And Places To WatchAccording to observational guidance, the planets will gather in the pre-dawn eastern sky and will be visible across regions like North America, Europe, Asia and Australia. The ideal viewing window globally falls around 4:30 am to 5:30 am local time.Will It Be Visible In India?Yes, but you’ll need a bit of patience. In India, the sweet spot is roughly 30 minutes before sunrise, which means around 5:00 am to 5:50 am IST, depending on your city. Eastern cities like Kolkata will see daylight sooner, while Mumbai gets a slightly longer viewing window. Southern cities such as Bengaluru, Chennai and Hyderabad may have a slight advantage, thanks to their position closer to the equator, which places the planets a bit higher above the horizon. Northern regions can still catch the show, though visibility might be a touch more challenging.
