Astronomers have chanced on a brand unique comet, dubbed C/2025 V1 (Borisov), which is set to form its closest means to every Earth and the sun. Some researchers have controversially linked it to the recent interstellar visitor 3I/ATLAS, nonetheless there is never any association between the 2.

A by no formula-sooner than-seen comet that shares some minor similarities with the rotten interstellar object 3I/ATLAS is set to form its closest means to our planet appropriate about a days after it used to be first spotted speeding toward us.
Nonetheless, despite some suggestions to the contrary, the newly chanced on comet is never any longer associated to our recent interstellar visitor, and practically surely originated interior the photo voltaic machine.
C/2025 V1 has an apparent magnitude of round 13.8, making it too faint to be seen with the naked seek for. Nonetheless, the unique comet would be seen to stargazers with a first price telescope or a pair of stargazing binoculars. It’s a ways for the time being positioned in the constellation Virgo and is most clearly seen appropriate sooner than crack of morning time, according to TheSkyLive.com.
3I/ATLAS is only the third ISO ever detected in the photo voltaic machine, and potentially the most up-to-date since Comet Borisov in 2019. (This photo of 3I/ATLAS used to be captured by the Hubble Discipline Telescope in August.) (Image credit rating: NASA/ESA)
If the title “Borisov” rings a bell, it’s because of Gennadiy Borisov additionally chanced on the second-known interstellar object (ISO), dubbed “Comet Borisov,” in 2019. Fancy 3I/ATLAS, which used to be first spotted in early July, this alien comet used to be ejected by a a ways flung star in the Milky Way and sailed via home for billions of years sooner than coincidentally capturing shiny via our cosmic neighborhood at extremely excessive speeds.
This association, along with some additional anomalous traits, used to be ample for some to scheme comparisons between C/2025 V1 and 3I/ATLAS. They integrated the notorious Harvard University astrophysicist and alien-hunter Avi Loeb, who described it as a “nearly interstellar object” in a recent weblog post.
How can an object be “nearly interstellar”? It comes down to its orbit. C/2025 V1 is a little bit uncommon, given its excessive eccentricity, meaning that it’s traveling toward the sun along a in point of fact straight trajectory. Here is an analogous to, even supposing no longer as gruesome as, the trajectory of 3I/ATLAS — and is the predominant reason for potentially the most up to date comparisons, Loeb wrote. Fancy in some recent photos of 3I/ATLAS, the unique comet additionally appears to be like to be to be lacking its tail, he added.

C/2025 V1 used to be chanced on whereas 3I/ATLAS used to be mild immediate hidden from us, due to it being positioned on the reverse facet of the sun to Earth. This has led some unique shops to speculate that C/2025 V1 would be an alien probe that used to be secretly deployed by its “mothership” 3I/ATLAS, which is a notion that used to be first postulated by Loeb shortly after potentially the most up to date ISO used to be chanced on.
Nonetheless, in his most up to date post, Loeb downplayed this concept, writing that “C/2025 V1 is not related to 3I/ATLAS if it did not employ non-gravitational propulsion.” The distance between the 2 objects at their minimum separation used to be additionally round 140 million miles (225 million km), which is probably going too colossal to screen an association between them, he added.
Avi Loeb used to be one of the first researchers to suggest that 3I/ATLAS is an alien spacecraft in cover. He additionally made the same claims about the first ISO ‘Oumuamua wait on in 2017.

As a replacement, the unique comet likely originates from the Oort Cloud — a big reservoir of comets and diverse frigid objects positioned approach the outer fringe of the photo voltaic machine. Nonetheless, its beginning point and orbital trajectory have no longer yet been properly calculated.
As for 3I/ATLAS, the alien comet has now reappeared from its short stint in the wait on of the sun, having reached perihelion on Oct. 29. This photo voltaic flyby used to be vital for several diverse reasons, together with an unexpected brightening tournament and a non permanent colour alternate. It has now started its dawdle wait on out of the photo voltaic machine and will reach its closest point to Earth on Dec. 19.
The ISO has displayed a collection of diverse anomalous traits, together with a highly irradiated surface and a puzzling anti-tail. Nonetheless, despite what some of us claim, there is never any legitimate proof that 3I/ATLAS is anything else diverse than a comet — appropriate admire C/2025 V1.
