Beyond the fact that it is the third known intersteller object to enter our solar system, “We know anyone a lot,” said Larry Deneo, co-intelligent explorer in Atlas, said, “said. A telescope in chili 3i/Atlas was seen on 1 July 2025.
When scientists say “we don’t know,” it’s not at all, but at least it is honest.
Astronomers know that 3i/Atlas is a comet that is about 670 million kilometers (416 million mi) from the Sun. Depending on current projects, this planet is no threat to Earth.
“Scientists are still determining the velocity and trajectory to an extent that will allow exact predictions for the future,” Richard Moisal wrote, who is in an email to DW, head of the European Space Agency’s planetary office.
It is about 240 million kilometers away for our planet, when it will fly in October. This is more than 1.5 times the distance between us and the Sun, and is about 624 times the distance between the Earth and our Moon. Therefore it is about 20 kilometers (12.4 miles) wide and travels at about 60 kilometers per second (at an impressive 134,000 miles).
But all these relative Elli Basic data-very data that allowed astronomers to the asteroid terrestrial-effect on Chili on the final warning system. When they are seen the object on an unusual trajectory, they immediately started tracking and measuring it.
Then, other binoculars based on binoculars in Hawaii and Australia began to monitor objects and progressed the flying items and confirmed it as an intersteller comet.
“We are starting [normal] Comentary Activity, “Wrote Moissl.
Open Questions about Comet 3i/Atlas?
Comat 3I/Atlas flew through helicepier to enter our solar system. Heliosphier is a barrier that protects us from intersteller winds and radiation.
However, Heliosphor is an incomplete barrier – some intersteler is through radiation, and it does not clearly prevent icy intergalactic wanderers such as 3i/Atlas.
In our solar system, the intersteler items are considered quite rare. The first known intersteller object was found in 1i/’OUMUAMUA, 2017, and 2i/Borisov, found in 2019.
“This is only the third intersteller [object] An accurate forecast of the expected frequency at this point is not possible at any time, “MoissL wrote.
But the telescope has got more technology advanced and scientists now scan the night sky continuously. So we can start looking at more of them.
The ESA, a colleague of ESA, Michael Kooppers, said, “Space and time in Time in the Vera Rubins Telescope in Chile goes online. It is more efficient than the current surveys and expands to detect the new interester objects in the next 10 years.”
Kueppers is a comet interceptor project scientist. The Comat Interceptor is a spacecraft that will relax in a “parking orbit” and prevent distant comets and asteroids if they come very close to the Earth. It is going to be launched in 2029.
3i/Atlas came from?
Small (and clear) the answer is that comets, such as 3i/Atlas, 1i/’OUMUAMUA and 2i/Borisov, come from other planetary systems.
Like comets and asteroids within our solar system, intersteller objects are considered to be untouched samples from elsewhere in our galaxy, Milky Way, if there are not pieces from the onset of the universe.
MoissL stated that the new object “came from the direction of the” Galactic Center area broadly, “as the name suggests, the center of Milky Way is towards the center. But astronomers do not know that this is an exact original or “home star”.
Depending on its brightness, 3i/atlas appears to be larger than the other two stray comets – 1i/’OUMUAMUA and 2i/Borisov – which is believed to have entered a separate area of Milky Way in our solar system.
Astronomers want to continue monitoring 3i/atlas to assess its composition and behavior. ESA stated that as an active comet, it can be hot because it becomes close to the earth, and “submate” – when frozen gases in a comet are converted into vapor, make a glowing coma and a mark of dust and ice particles.
You should see it from Earth with a telescope by September, but “you will need a large telescope to see it,” DW wrote to DW in an email by Jonathan McDowell of Harvard-Smithsonian Center for Astrophysics in an email.
When it is closest to the Earth, it will be hidden by the Sun but then rapier by the beginning of December.
