Rare Interstellar Visitor: Third Confirmed Object Dazzles as It Passes Through Our Solar System (Latest Update)

Scientists recently confirmed the discovery of an interstellar object traveling through our solar system. Named 3I/Atlas, this is only the third interstellar visitor we’ve detected, even though researchers believe many more might go unnoticed.

This object is thought to be the largest interstellar find yet. Classified as a comet, it appears fuzzy and may have gas and possibly a short tail, according to Peter Veres from the International Astronomical Union’s Minor Planet Center.

Richard Moissl, head of planetary defense at the European Space Agency, reassured the public that 3I/Atlas poses no danger to Earth. It will pass safely inside Mars’s orbit, speeding at over 60 kilometers (37 miles) per second. Unlike most celestial bodies that orbit the sun, this object is on a trajectory that takes it back into interstellar space.

Jonathan McDowell, an astronomer at the Harvard-Smithsonian Center for Astrophysics, noted, “These ice balls likely form near stars. When another star passes by, it can pull one away, and then it wanders through our galaxy.” A Chilean observatory, part of NASA’s ATLAS survey, first spotted the object.

3I/Atlas is estimated to be between 10 to 20 kilometers wide, which makes it notable among interstellar objects. However, its actual size could vary if it’s mostly made of ice, which can reflect more light. As it approaches the sun, it will become brighter, reaching its closest point on October 29 before moving away from our solar system over the next few years.

This discovery marks only the third time we’ve recognized an object entering from interstellar space. The first was ‘Oumuamua in 2017, which sparked plenty of debate, including claims of it being alien technology—an idea that has since been refuted. The second, 2I/Borisov, was identified in 2019.

While there’s no suggestion that 3I/Atlas is artificial, researchers around the globe are keen to learn more about its shape and composition. Mark Norris from the University of Central Lancashire mentioned that this object is moving faster than previous finds. Interestingly, estimates suggest there could be around 10,000 interstellar objects drifting in our solar system, many likely smaller than 3I/Atlas. With the help of new telescopes like the Vera C. Rubin Observatory in Chile, astronomers could start detecting these distant visitors more frequently.

Studying these interstellar objects could provide valuable insights about the universe and the origins of life. For example, finding organic compounds, like amino acids, on such objects would increase our confidence that life could exist elsewhere in the cosmos.

3I/Atlas’ journey offers a fascinating glimpse into the greater mysteries of space and reminds us how much we still have to learn about the universe we live in.
