How big is the interstellar object 3I/ATLAS? Scientists reveal stunning new details
A massive interstellar object, 3I/ATLAS, discovered by NASA, is sparking global fascination and conspiracy theories online, with some suggesting it could be an alien probe. Scientists are racing to understand its true nature as it passes Mars, wit...

This strange object moving through our solar system is getting a lot of attention around the world and making people wonder about the universe. The huge body, which is called 3I/ATLAS, could be as big as Manhattan and weigh an incredible 33 billion tons.

NASA first found it in early July, and now a lot of people are studying and guessing about it, including Harvard astrophysicist Avi Loeb, who thinks it might not just be a comet but an ancient alien probe. Scientists are racing to find out what this interstellar visitor really is as it moves through space, as per a report by Jalopnik.
What is 3I/ATLAS and why are scientists so inclined towards it?
Scientists are observing the interstellar object 3I/ATLAS. Harvard astrophysicist Avi Loeb says that this cosmic traveler could be an amazing three miles wide and weigh about 33 billion tons, which is a lot more than what scientists thought at first.Could it really be technology from another world?
Loeb's theory has once again sparked interest and debate. He wrote about the object's strange features and how unlikely it is to find such a big interstellar body by chance in a recent Medium post. He said, ""Given the limited reservoir of heavy elements, we should have discovered on the order of a hundred thousand interstellar objects on the 0.1-kilometer scale of 1I/`Oumuamua before finding 3I/ATLAS, yet we only detected two interstellar objects previously."
Since 3I/ATLAS is so rare and moves so quickly, some people think it might not be completely natural. Loeb also said that if scientists see any strange movements as it moves, that could mean that it is being propelled by a "technologically manufactured engine,” as per a report by Jalopnik.

What happens next when 3I/ATLAS passes Mars?
NASA has made an animation that shows how the object will move through the solar system and how close it will come to Mars, Venus, and Jupiter. Later, when it leaves our solar system, astronomers want to find it again near Jupiter to make more observations.
What does this mean for the search for life outside of Earth?
3I/ATLAS has sparked interest in what and who might be out there, whether it is a comet, a probe, or something else. Loeb's research has kept people interested in the idea that these interstellar visitors could be "some evidence of alien intelligence," as the New York Post pointed out.
Scientists still think it's most likely a huge comet, even though it's unlike any other comet they've seen. After it finishes its trip through our solar system, it will go on to deep space, where it might catch the attention of other civilizations, if they exist, as per a report by Jalopnik.

FAQs
What does 3I/ATLAS mean?
3I/ATLAS is a huge object from another star system that is currently flying through our solar system. It could be a comet or, as some people think, an old alien probe.
When will scientists take a closer look at it?
NASA thinks that observations will be clearer around October 3, when the object gets close to Mars.
