Comet 3I/ATLAS Today: Interstellar Visitor Nears Closest Approach to Earth — What’s Happening on Dec. 18, 2025 and How to Watch

December 18, 2025 — The interstellar comet 3I/ATLAS (sometimes written as 3I/Atlas) is back in the spotlight today as it heads into a key milestone: its closest approach to Earth early Friday, Dec. 19. It won’t be a dramatic “near miss” in everyday terms—NASA emphasizes the comet will remain about 1.8 astronomical units away (roughly 170 million miles / 270 million kilometers, nearly twice the Earth–Sun distance)—but in astronomy, that’s close enough to trigger an all-hands observation push across telescopes and spacecraft. NASA Science Today’s coverage (Dec. 18) is dominated by two themes: how to watch the flyby in real time, and what scientists are learning from this rare visitor from another star system—only

Rocket Launches Today, Dec. 17, 2025: Ariane 6 Delivers Galileo Satellites as SpaceX Targets Two Starlink Missions

Europe’s newest heavy-lift rocket notched another high-profile success in the early hours of December 17, 2025, sending two Galileo navigation satellites toward medium Earth orbit—while the global launch calendar stays packed with two SpaceX Falcon 9 Starlink flights still on the schedule for later today. In the Asia-Pacific region, Japan’s H3 rocket launch was canceled after an issue was found in ground facilities. And in South America, a highly watched debut attempt from Brazil’s Alcântara spaceport was pushed back, as South Korean startup INNOSPACE rescheduled its first commercial orbital mission. 이노스페이스+4Newsroom Arianespace+4European Space Agency+4 Taken together, the day’s launch news shows a space sector moving in two directions at once: established

Night Sky Tonight December 17, 2025: Moon Phase, Planets, Meteor Showers and Today’s Space News

If you’ve been waiting for a truly dark December evening to step outside and let your eyes drink in the stars, tonight is one of the best opportunities of the month. The Moon is in a very thin waning crescent phase, sliding toward a late-week new moon—meaning the night sky is largely free of moonlight.

Comet 3I/ATLAS Today (Dec. 16, 2025): Interstellar Visitor Nears Closest Approach to Earth on Dec. 19

As of Tuesday, December 16, 2025, the interstellar comet known as 3I/ATLAS—a rare visitor from beyond our solar system—is drawing intense attention ahead of its closest approach to Earth on Friday, Dec. 19. Despite dramatic headlines and online rumors, reputable agencies are consistent on the key point: 3I/ATLAS poses no threat to Earth, and will remain about 1.8 astronomical units (AU) away—roughly 170 million miles (270 million kilometers).

Updated: December 14, 2025 December’s night sky is delivering exactly what skywatchers hope for: long hours of darkness, bright planets, and two headline-grabbing celestial events arriving back-to-back.

Comet 3I/ATLAS: Green-Glowing Interstellar Visitor Nears Its Closest Earth Pass on Dec. 19, 2025

Comet 3I/ATLAS: Green-Glowing Interstellar Visitor Nears Its Closest Earth Pass on Dec. 19, 2025

Updated: December 14, 2025 A rare messenger from another star system is sliding through our solar system right now—and it’s putting on a subtle but scientifically rich show. Comet 3I/ATLAS (also designated C/2025 N1 (ATLAS)) is only the third confirmed interstellar object ever observed inside our solar system. Over the last several days, fresh reporting and new datasets have sharpened the picture: the comet’s coma has taken on a faint green glow, and X-ray observatories are now seeing the interaction between its escaping gases and the solar wind—an unusual multiwavelength campaign that’s turning 3I/ATLAS into one of the most intensively monitored comets of 2025.
