Rare seven-planet alignment to dazzle sky in February, visible to naked eye – Here’s how to watch it

February 2025 Planet Parade

A rare planetary alignment will light up the night sky. In late February, seven planets will appear together for one night. Venus, Mars, Jupiter, Saturn, Uranus, Neptune, and Mercury will be visible. The event promises a stunning display for astronomy lovers worldwide.

The planets move at different speeds around the Sun. Mercury, the fastest, takes just 88 days to orbit. Neptune, the slowest, takes nearly 165 years to complete one revolution. Their varying speeds occasionally create alignments visible from Earth.

The Science Behind Planetary Alignments

Planetary alignments happen when multiple planets line up. Though they orbit the Sun in a flat plane, their speeds differ. This results in occasional celestial groupings seen from Earth.

Brighter planets like Mercury, Venus, Mars, and Jupiter will be visible. Saturn will also shine, but Uranus and Neptune may need telescopes. Astronomers use these alignments to study planetary orbits and exoplanets. The transit method, for example, detects planets outside our Solar System.

NASA launched Voyager probes during a similar alignment in 1977. Voyager 2 remains the only spacecraft to visit Uranus and Neptune.

Could Alignments Help in Space Research?

Astronomers also use alignments to study distant galaxies. Gravitational lensing helps magnify light from far-off cosmic objects. Some researchers believe alien civilisations might use alignments to send signals.

This rare event offers a chance to observe celestial wonders. Stargazers can enjoy the sight while scientists study its significance.
