SPACE FACTS: DAY 206/365🧪🔭🛰️
Sungrazing comets pass within a few thousand miles of the sun at perihelion. Such a close passage makes them very bright but also (usually) destroys them. Most follow the Kreutz Path and are likely chunks of a large sungrazing comet that broke apart centuries ago.

🚨 Newly discovered object, provisional 6AC4721, has been identified as a Kreutz-group sungrazing comet.
In mag. 18, despite being very faint, it shows activity beyond 2 AU. Perihelion is expected in early April 2026. Likely to disintegrate, but scientifically intriguing 🔭

An alternate Solar System where Jupiter and Saturn got caught up in terrible shenanigans; Saturn is ejected, their satellite system destroyed, and Jupiter got sent into sungrazing orbit, eventually becoming a hot Jupiter.
Inner planets got ejected. Neptune and maybe Caelus barely survived.

A new #comet - C/2026 A1 (MAPS) - is brightening as it heads into the inner solar system. It’s a sungrazing comet that'll get scorchingly close to the sun in April. If it survives, it might put on a show in Earth's skies around Easter. Read more: buff.ly/9iazqDt

Sungrazer comets
'Sungrazing' comets have been observed for many hundreds of years. These are comets which travel very close to the Sun, where they light up brightly and often break into smaller pieces.
