INTERSTELLAR COMET 3I/ATLAS

● 3I/ATLAS is also named C/2025 N1.
● 3I/ATLAS was discovered on 1 July 2025 by ATLAS.
● ATLAS means Asteroid Terrestrial-impact Last Alert System. 🔭

● 3I/ATLAS shows a hyperbolic orbit that proves interstellar origin.
● 3I/ATLAS has a nucleus estimated between one and five kilometers.
● 3I/ATLAS develops a diffuse coma and a faint tail. 🌠

● 3I/ATLAS passes perihelion on 29 or 30 October 2025.
● 3I/ATLAS reaches about 1.35 astronomical units from the Sun.
● 3I/ATLAS passes 1.8 astronomical units from Earth on 19 December 2025. 🌍

● 3I/ATLAS will be visible with telescopes in July and September.
● 3I/ATLAS will be hidden by the Sun in October.
● 3I/ATLAS will reappear in December in the night sky. 🌙

● 3I/ATLAS may be more than seven billion years old.
● 3I/ATLAS may have formed in the thick disk of the Milky Way.
● 3I/ATLAS is older than the Solar System itself. ⏳

ASTRONOMICAL TAIL ANALYSIS

● ʻOumuamua shows no tail because it lacks volatile ice.
● 3I/ATLAS shows a faint tail because some ice sublimates.
● The faint tail of 3I/ATLAS confirms its comet nature. 🌬️

● The weak tail means a small active surface on the nucleus.
● The weak tail also means old age and volatile loss.
● The weak tail will likely grow near perihelion in October. ☄️
