Mysterious Manhattan-Sized Interstellar Object 3I/ATLAS Sparks Alien Theories Ahead of Halloween
Astronomers identified interstellar object 3I/ATLAS on July 1, 2025, with a nucleus up to five miles wide and a mass of about 33 billion tons. The comet will pass closest to the Sun on October 30, 2025, just inside Mars’s orbit, never coming closer than 170 million miles to Earth. NASA and international teams are tracking its path and composition. Most scientists say it is a natural comet, despite some speculation about artificial origins.
