NASA said the comet will make its closest approach to the sun in late October, scooting between the orbits of Mars and Earth – but closer to the red planet than us at a safe 150 million miles away.

The comet won't swing close to Earth like Tsuchinshan-Atlas did last year. Other notable flybys included Neowise in 2020 and Hale-Bopp and Hyakutake in the 1990s.

A newly discovered green comet tracked by telescopes has likely broken apart as it swung by the sun, dashing hopes of a naked-eye spectacle.

A newly discovered comet, called C/2025 F2 (SWAN), may have disintegrated. But the remnants are still visible.

A recently discovered comet is currently gracing our morning skies, with its signature green glow and long tail trailing behind. Comet SWAN25F is speeding toward the Sun for a dangerously close ...
