Massive Solar Storm Nearly Hits Earth
In July 2012, a significant coronal mass ejection (CME) was emitted by the Sun, creating a powerful solar storm that traveled through space. This storm was notable for its intensity and potential impact on Earth’s electrical systems. Scientists noted that if the CME had struck Earth directly, it could have led to damages estimated at up to $2.6 trillion, affecting power grids and satellite operations worldwide. Fortunately, the storm missed Earth by just nine days, averting a potential crisis for global technology infrastructure.

On September 29, 2004, the asteroid 4179 Toutatis made a close approach to Earth, coming within four lunar distances from our planet. Discovered in 1989, Toutatis is an Apollo-type asteroid with an irregular shape measuring approximately 4.5 kilometers in length. This proximity allowed scientists to gather significant data on its size, shape, and orbit. The event marked an opportunity for researchers to study near-Earth objects more closely for both scientific interest and planetary defense strategies.

A rare astronomical alignment occurred when all nine recognized planets in the solar system aligned on one side of the Sun. This astronomical phenomenon, known as syzygy, included Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and the then-recognized ninth planet, Pluto. While such alignments are visually spectacular, they have minimal impact on Earth, aside from providing a thrilling spectacle for astronomers and stargazers alike across the globe. Observers were treated to a unique celestial sight, as scientists and enthusiasts remarked on the beauty and rarity of the event.
