Comet 3I/Atlas follows hyperbolic path and avoids solar gravity
An interstellar comet, identified as 3I/Atlas, crosses the solar system at a speed of 57 km/s, confirming its origin outside our galaxy. Recently discovered, the object follows a hyperbolic trajectory, which prevents it from being captured by the Sun’s gravity. Astronomers are monitoring the phenomenon, which marks the third recorded interstellar comet, after Oumuamua and Borisov. The event, observed by global telescopes, takes place in November 2025.
3I/Atlas will not form a solar orbit, unlike local comets. His visit, expected to last weeks, offers a unique opportunity for studies. Initial data indicate that the comet maintains a speed greater than that necessary to escape the solar gravitational influence.
- Recorded speed: 57 km/s, higher than Oumuamua’s 26 km/s and Borisov’s 33 km/s.
- Trajectory: Hyperbolic, with deviation caused by solar gravity.
- Origin: Distant stellar system, confirmed by spectroscopic analysis.
Continuous monitoring refines calculations about the point of closest approach to the Sun.
Interstellar origin confirmed
3I/Atlas analysis reveals distinct chemical proportions of solar comets. Telescopes capture spectra that indicate common elements, but in unique configurations, reinforcing their classification as an external object.
The data suggests that the comet was expelled from its original system by gravitational interactions or stellar explosions. He travelsthrough interstellar space millions of years ago before crossing the solar system.
Trajectory and behavior
The 3I/Atlas follows a path that differentiates it from solar comets, which orbit the Sun. Its speed exceeds that necessary to escape the Sun’s gravity at each point on its trajectory.
Interaction with the Sun changes its direction, but does not hold it back. Computer models predict that the comet will leave the solar system after a few weeks.
Global observatories monitor the object in real time. The passage is described as a “gravitational slingshot” effect.
Comparison with other comets
3I/Atlas is the third interstellar comet identified, after Oumuamua, in 2017, and Borisov, in 2019. Unlike solar comets, which reach high speeds only at perihelion, 3I/Atlas maintains its speed inherited from the galactic environment.
Spectroscopy reveals distinct chemical compositions, with proportions of elements not compatible with materials from the solar system.
Oumuamua showed unusual acceleration, attributed to the release of gases. 3I/Atlas does not show similar signs so far.
Real-time monitoring
International observatories adjust 3I/Atlas orbital data daily. The comet’s kinetic energy overcomes the solar attraction, ensuring its exit from the system.
Detailed monitoring allows you to predict the angle of deviation caused by the Sun. After passing, the comet will continue its journey through deep space.
What the passage reveals
The presence of 3I/Atlas offers insights into the formation of distant star systems. Its chemical composition, distinct from solar comets, suggests variations in planetary formation processes in other stars.
Future studies
The comet’s passage mobilizes scientists to collect additional data. New observations may shed light on the mechanisms that expel interstellar objects from their systems.
