On the evening of January 21, a remarkable astronomical event will take place as six planets, Mars, Jupiter, Uranus, Neptune, Venus, and Saturn, align in a straight line, creating a stunning celestial "parade." This rare occurrence, known as a planetary conjunction, allows several planets to line up in a section of the sky.
While Uranus and Neptune will need binoculars or telescopes for viewing, the other four can be seen with the naked eye. This alignment will be observable over the next few weeks, presenting a unique opportunity for stargazers.
Notably, on February 28, a seven-planet conjunction featuring Saturn, Mercury, Venus, Jupiter, Mars, Uranus, and Neptune will enhance the spectacle even more.
Planetary conjunctions happen when three or more planets align on the same side of the Sun, which, while infrequent, provides valuable chances for scientific observation and public interest in astronomy.
The planets travel around the Sun at varying speeds and distances. Mercury completes its orbit in 88 days, while Neptune takes approximately 165 Earth years. Each planet has a tilted axis and elliptical orbit, constantly shifting their relative positions.

Although the planets may appear closely positioned during the alignment, the actual distances are immense—millions or even billions of kilometers apart. This visual phenomenon is harmless and merely an illusion from our viewpoint on Earth.
Historically, planetary alignments have posed no threats. Instead of concern, this extraordinary event invites us to enjoy and deepen our understanding of the cosmos.
