A striking “green comet” about the size of a little city is illuminating the night sky as it nears Earth next week. Specialists forecast the substantial iceball might quickly be completely ejected from the planetary system, dooming it to wander through interstellar area– like the “alien” comet 3I/ATLAS
The brand-new comet, called C/2024 E1 (Wierzchoś)was found in March 2024 by Polish astronomer Kacper Wierzchośwho identified the icy things cruising towards us with a 4.9-foot (1.5 meter) telescope at the Mount Lemmon Observatory in Arizona. The comet has actually given that been observed by the James Webb Space Telescope (JWST), which identified big quantities of co2 in its coma– the cloud of gas and dust that surrounds the comet’s icy shell.
An preliminary analysis of JWST information recommended that Comet Wierzchoś’nucleus has a size of around 8.5 miles (13.7 kilometers), which is approximately two-thirds the length of Manhattan and around 4 times the island’s width. A more current research studywhich has actually not yet been peer-reviewed, tips that this might be an overestimate.Comet Wierzchoś stems from the Oort cloud– the extensive tank of comets and other icy items hiding near the external edge of the planetary system — and is hyperbolic, implying that it has an open and flattened trajectory, and does not consistently orbit the sun. This is most likely the very first time it has actually ever ventured into the inner planetary system, the scientists presume.
Some scientists think that it has actually been gradually falling towards the sun for in between 1 million and 3 million years, although it is tough to inform for sure. A lot of specialists concur that the gravitational kick from its present solar slingshot will fire it out of our cosmic area permanently and into interstellar area, according to Spaceweather.com
Comet Wierzchoś has actually likely been set on a one-way trajectory out of the planetary system after its current solar slingshot.

It will quickly make its closest technique to Earth, on Tuesday (Feb. 17 ), when it will be around 94 million miles (151 million km)from our world– approximately the exact same range away as the sun.

Going, going, goneAccording to the scientists, it might take a number of years and even centuries for Comet Wierzchoś to formally leave the planetary system. As soon as it has, it will invest millions if not billions of years wandering through the Galaxysporadically travelling through other alien galaxy on its method.
This is precisely what took place to the interstellar comet 3I/ATLAS, that made headings in 2015 as it shot through the inner planetary system, having actually been tossed out by its home star most likely long before the sun was born
3I/ATLAS made headings in 2015 as it zoomed through the inner planetary system. It was photographed by several spacecraft throughout our cosmic area. (Image credit: NASA/Goddard/LASP/ CU Boulder/JPL-Caltech/University of Arizona/Southwest Research Institute/Lowell Observatory/Qicheng Zhang/ASU/MSSS )3I/ATLAS was Found in July and reached perihelion in late Octoberbefore swinging previous Earth in mid-DecemberThroughout this duration, it showed numerous uncommon attributes, which led some researchers to controversially propose that it might be an alien spacecraft — in spite of frustrating proof that it is a natural comet
It is now on its method revoke the planetary system and will likely travel through numerous other galaxy, similar to Comet Wierzchoś ultimately will.
How to see C/2024 E1 (Wierzchoś)Because Comet Wierzchoś passed perihelion, it has actually ended up being considerably brighter and grown a long tail of gas and dust, enabling astrophotographers to snap magnificent shots of it speeding throughout the night sky. Austrian astrophotographer Gerald Rhemann caught among the very best images of the iceball on Jan. 26 from a night sky reserve in Namibia (see above).
A lot of these images, consisting of Rhemann’s, reveal the comet’s coma radiant green. This unusual color is most likely connected to its high carbon material, as seen in previous cometsalthough the specific reason for its pigmentation has actually not been reported on by scientists.
The emerald iceball will not end up being intense adequate to be noticeable to the naked eye. It can be quickly identified with a good telescope or set of stargazing field glasses
Comet Wierzchoś was very first identified in March 2024. This picture was recorded by the Zwicky Transient Facility at California’s Palomar Observatory on Sept. 14, 2025. (Image credit: NASA/JPL-Caltech/IRSA/ ZTF)From the Northern Hemisphere, it will stay observable over the next couple of weeks and can be best found above the southwestern horizon after sundown, as it travels through the constellation Sculptor, according to EarthSky.comIt will be much easier to identify from the Southern Hemisphere.

2026 is forming up to be another bumper year for comet lovers, following on from the enjoyment of 3I/ATLAS, along with other comets like Lemmon and SWANin 2015.In current weeks, astronomers have identified a brand-new “sungrazer” cometcalled C/2026 A1 (MAPS), which might possibly end up being brilliant sufficient to be seen with the naked eye throughout the daytime in early April– if it endures its very close slingshot around the sun.
Another substantial iceball, called C/2025 R3 (PanSTARRS), might End up being noticeable without a telescope as it nears its closest indicate both the sun and Earth in late April.
With the assistance of the recently functional Vera C. Rubin Observatorysome scientists are likewise hoping that we might quickly discover much more concealed items — possibly consisting of the planetary system’s next interstellar visitor.
