An interstellar comet, identified as 3I/ATLAS, originating from another solar system, is at risk of collapsing due to the intense heat of Sol. Descoberto in 2023, the celestial object approaches perihelion, the closest point to the star, where extreme temperatures can fragment it. Astrônomos monitors the comet, which is already showing signs of instability, with observations indicating possible disintegration in the coming months. The event is rare, as interstellar comets cross our solar system only a few times a century.
3I/ATLAS was detected by the ATLAS project telescopes (Asteroid Terrestrial-impact Last Alert System). The hyperbolic trajectory of Sua confirms its origin outside the solar system, making it the third known interstellar comet, after ‘Oumuamua and 2I/Borisov. Dados As Preliminaries suggest that the comet, composed of ice and dust, may not resist solar thermal and gravitational forces.
- Observations indicate an increase in the release of gases, a sign of warming.
- The fragments can generate meteor showers visible in Terra.
- Telescopes like the Hubble follow the phenomenon in real time.
Origin and trajectory of the comet.
3I/ATLAS comes from an unknown region beyond the Oort cloud, thousands of light years away. Sua’s speed and orbit suggest it is not bound by solar gravity.
Astronomers estimate that the comet traveled millions of years before entering the solar system. The composition of Sua, rich in volatile compounds, makes it vulnerable to heat.
Risks of imminent collapse
The comet is just a few months away from reaching perihelion, expected in 2026. Observações has fissures in its nucleus, indicating possible fragmentation.
The proximity of Sol increases the sublimation of ice, releasing jets of gas.
The intense heat can destabilize the structure and cause it to completely collapse.
If it collapses, 3I/ATLAS could form a trail of debris in space.
Global monitoring
Telescopes across the globe track 3I/ATLAS, with data collected by observatories at Havaí and Chile. NASA and ESA collaborate to study the phenomenon.
Spectroscopic analysis reveals rare compounds, such as organic molecules, that may offer clues about the formation of distant star systems.
Monitoring also assesses whether comet fragments could reach Terra, although the risk is low.
Scientific impacts
The 3I/ATLAS survey offers a unique window into understanding interstellar objects. The composition of Sua differs from that of local comets, suggesting different chemical processes in its system of origin.
The possible disintegration could generate valuable data about the internal structure of comets.
Future Observations
Surveillance of the comet will intensify in the coming months, with a focus on perihelion. Astrônomos hopes to capture detailed images of possible fragmentations.
