Comet 3I/ATLAS zoomed past Earth last night as astronomers around the world continue to collect information on the interstellar visitor.
The comet made its closest technique at around 1 a.m. EST on Friday(Dec. 19), coming within about 168 million miles(270 million kilometers)of our world.
Comet 3I/ATLAS depends on a couple of miles broad and didn’t get close enough to be noticeable to the naked eye. Skywatchers observed it utilizing telescopes.
And last night was far from our last opportunity to see the comet. It will stay observable in the pre-dawn sky with a little telescope up until spring, according to NASAIf you do not have a telescope, then the finest method to see comet 3I/ATLAS is online.
The Virtual Telescope Project in Italy is hosting a livestream of the comet passing Earth at 11 p.m. EST on Friday. The livestream, which was arranged for last night however delayed due to rain, will include real-time pictures of the comet as it zooms towards Jupiter.
Comet 3I/ATLAS deserves having a look at due to the fact that it’s an unusual example of an interstellar things from beyond our planetary system. This is just the 3rd interstellar visitor ever found and might be the earliest comet ever seen

The comet’s origins have actually been the topic of significant speculation, the majority of infamously the duplicated recommendations that it might be an alien spacecraftAlmost all astronomers are positive that 3I/ATLAS is a comet from another galaxy
Scientist found comet 3I/ATLAS in July, when they identified an unidentified item racing along at around 137,000 miles per hour (221,000 km/h) within the orbit of Jupiter. Having actually swung past the sun, reaching the closest indicate our star (perihelion) at the end of October, the comet is now making its escape of our planetary system.
After getting day-to-day ask for actually months-I’m delighted to show you 3i/Atlas. The “Alien” comet, caught totally with my own devices. What do I think of it? I’ll share my observations in the replies. pic.twitter.com/XfPDhosoJNDecember 17, 2025
What’s next for comet 3I/ATLAS?Comet 3I/ATLAS will pass Jupiter next, where it is anticipated to make its closest technique on March 15, 2026, according to NASAThe comet will get much closer to Jupiter than it did to Earth, coming within about 33 million miles (54 million km) of the gas giant. Spacecraft stationed at Jupiter, like Junomay be able to observe the comet as it approaches.
The interstellar trespasser will then cross Saturn’s orbit in July 2026; Uranus’ orbit in April 2027; and Neptune’s orbit in March 2028. It will not get close to any of these worlds. You can track comet 3I/ATLAS on your own utilizing NASA’s Eyes on the Solar System simulation of the comet’s trajectory.
Scientists will watch on comet 3I/ATLAS while it stays in our cosmic community. There’s a lot they still do not understand about its residential or commercial properties. The size of the comet is unpredictable. Hubble Space Telescope observations recommend that it’s someplace in between 1,440 feet (440 meters) and 3.5 miles (5.6 km) broad.
Scientists likewise do not understand which galaxy created comet 3I/ATLAS, and they might never ever discover. The comet took a trip a long method and might have been speeding through area for billions of years before visiting our planetary system.
