The comet 3I/ATLAS, originating from another star system, faces risk of fragmentation due to high solar temperatures. Discovered in 2023 by the ATLAS project, the object follows a hyperbolic trajectory and approaches the closest point to the Sun. Observations indicate accelerated gas release and fissures in the nucleus.
Astronomers from various observatories monitor the phenomenon in real time. The third known interstellar comet has a composition rich in volatile ices. Its instability increases with proximity to the star.
- Telescopes in Hawaii and Chile record daily data.
- Spectroscopic analyses identify rare organic molecules.
- Collaboration between NASA and ESA coordinates monitoring.
Origin beyond the Oort cloud
The 3I/ATLAS traveled millions of years before entering the solar system. Its high speed confirms it does not orbit the Sun. The region of origin remains unknown.
Composition includes dust and volatile compounds different from local comets. Studies compare it with ‘Oumuamua and 2I/Borisov.
Signs of intense heating
Observations show increase in ice sublimation. Gas jets emerge from the nucleus. Fissures expand rapidly. Perihelion occurs in 2026 at a minimum distance from the Sun. Thermal and gravitational forces pressure the structure.
Possible fragments in space
If rupture occurs, debris will form an extensive trail. Part may generate meteor showers visible from Earth. Risk of planet impact is minimal. Telescopes like Hubble capture detailed images. Data help understand resistance of interstellar objects.
Confirmed hyperbolic trajectory
The comet maintains escape velocity from the solar system. It will not be captured by local gravity. After perihelion, it will leave the solar neighborhood.
Monitoring with advanced telescopes
Ground-based and space observatories intensify surveillance. Updates occur weekly. Teams analyze variations in brightness.
Unique chemical composition
Spectroscopy reveals presence of rare elements. Organic molecules suggest processes in distant systems. Comparisons with solar comets highlight differences.
Predictions for the coming months
Approach accelerates changes in the nucleus. Partial fragmentation is already likely. Future observations focus on jets and ejections.
The study of 3I/ATLAS provides information on the formation of bodies in other star systems and their interaction with stars like the Sun, contributing to models of interstellar dynamics and chemical composition of extrasolar objects.
