Chennai residents and stargazers across India have a celestial treat in store on February 28th: a rare alignment of six planets and the Moon. Whereas not a perfectly straight line, the planets Mercury, Venus, Saturn, Uranus, Neptune and Jupiter will appear in the night sky shortly after sunset, offering a captivating spectacle for those with clear skies and, in some cases, a telescope. This planetary alignment, often referred to as a “planet parade,” is generating excitement among astronomy enthusiasts.
The event promises a unique viewing opportunity, though conditions will be key. Experts caution that light pollution could significantly hinder visibility, particularly for the fainter planets. S Soundararaja Perumal, former executive director of the Birla Planetarium, explained that Mercury, being closest to the horizon, may be visible for a very limited time, potentially disappearing by around 7 pm. “Light pollution could create it difficult to view them. If the sky is clear, we may be able to see the partial phase for a few minutes after moonrise,” he said, adding that Jupiter is expected to be the brightest of the group.
What to Expect in the Night Sky
The arrangement won’t be a neat, linear formation. According to observations, Mercury, Venus, Saturn, Uranus, and Neptune will be positioned low on the western horizon, while Jupiter will appear higher in the eastern sky alongside the Moon. This configuration means that the planets may only be visible for approximately 30 minutes after sunset, provided the atmospheric conditions are favorable. NASA has indicated that the planets will be visible throughout February, but the alignment will be most pronounced towards the end of the month.
While four of the planets – Mercury, Venus, Saturn, and Jupiter – are potentially visible to the naked eye under clear, dark skies, spotting Uranus and Neptune will require optical assistance, such as a telescope. Perumal noted that the visual magnitude of Uranus and Neptune is around 8, which is fainter than the typical human eye can perceive (a limit of around 6). A telescope will be essential to resolve these distant ice giants.
Past Planetary Alignments and Future Events
This isn’t the first time such a planetary gathering has occurred. In January 2025, six planets – Venus, Saturn, Jupiter, Mars, Uranus, and Neptune – formed a similar parade in the night sky. Mercury joined the alignment in February 2025, due to its relatively short orbital period of 88 days around the Sun. Similar conjunctions have been observed before, such as a notable alignment of Venus, Jupiter, and Mercury in February 2012.
The term “planet parade” has gained popularity in recent years, alongside other skywatching phenomena like supermoons and eclipses. These events capture public imagination and encourage people to appear up and appreciate the wonders of the universe. The increasing interest in astronomy is fueled by readily available information and the accessibility of affordable telescopes and binoculars.
Tips for Viewing the Alignment
To maximize your chances of observing this celestial event, locate a location away from city lights with an unobstructed view of the western and eastern horizons. Allow your eyes to adjust to the darkness for at least 20-30 minutes. Binoculars can enhance the view of the brighter planets, while a telescope is recommended for spotting Uranus and Neptune. Checking a stargazing app or website can help you pinpoint the exact locations of the planets in the sky.
While the alignment itself may not be a perfectly straight line, the proximity of these planets in the night sky offers a rare and beautiful sight. The event serves as a reminder of the dynamic nature of our solar system and the constant movement of the planets in their orbits around the Sun.
Looking ahead, astronomers continue to monitor planetary movements and predict future alignments. While no other major planetary parades are currently scheduled in the immediate future, ongoing observations will undoubtedly reveal more opportunities to witness the beauty and complexity of our cosmic neighborhood. For those interested in learning more about upcoming astronomical events, resources like NASA’s website and local planetariums offer valuable information and guidance.
