Astronomers are laying out welcome mats for newly discovered visitors making their way through our solar system.
This particular object is categorized as a comet and marks only the third confirmed interstellar visitor in recorded history to traverse our cosmic neighborhood.
The comet, named 3i/Atlas, poses no threat to Earth, maintaining a distance of about 150 million miles while it accelerates. As reported by NASA.
This interstellar comet was initially discovered on Tuesday by The final alert system for the asteroid’s terrestrial impact (Atlas) located in Rio Hartado, Chile. The research telescope, funded by NASA, is actually two telescopes from Hawaii and one in Chile, in addition to a fourth in South Africa, all dedicated to scanning the sky multiple times nightly for asteroids that could threaten Earth.
Researchers examined archived data from three different Atlas telescopes and Zwick temporary facilities at the Palomar Observatory in California, uncovering observations that would corroborate the findings. Other telescopes worldwide have also joined the initiative, as stated by NASA.
“ESA’s planetary defenders are currently monitoring an object provisionally known as #A11PL3Z, utilizing telescopes from around the globe,” the European Space Agency announced in a post on X this Wednesday.

The comet is located around 420 million miles away and is rapidly traveling from the direction of the constellation Sagittarius. NASA commented in a blog post regarding the findings. Sagittarius is a prominent constellation in the Southern Hemisphere and indicates the center of the Milky Way galaxy.
The agency noted that 3i/Atlas will make its closest approach to the sun around October 30th, passing roughly 130 million miles away, close to Mars’ orbit.
NASA indicated that the comet will remain observable from ground-based observatories until September, providing scientists with the opportunity to gather additional details about these cosmic visitors, including their size. After September, 3i/Atlas will be too close to the sun for telescopes to observe, but it is expected to become visible again in early December, as it reemerges on the far side of the sun.
The upcoming months will present a rare chance to study these celestial tourists traveling through the solar system. The first confirmed interstellar object, observed in 2017 by the University of Hawaii’s Pan-Starrs1 telescope, was the rocky body named “Oumuamua” (Hawaiian for first visitor), notable for its reddish hue and elongated cigar-like shape. As noted by NASA.
The only other known interstellar visitor is 2i/Borisov, a comet discovered in 2019 by amateur astronomer Gennady Borisov.
