This diagram shows the trajectory of interstellar comet 3I/ATLAS as it passes through the solar system. It will make its closest approach to the Sun in October.  It is currently about 4.5 au (about 416 million miles or 670 million km) from the Sun. 3I/ATLAS will reach its closest approach to the Sun around Oct. 30, at a distance of 1.4 au (about 130 million miles or 210 million km) — just inside the orbit of Mars. 3I-Atlas Closest to Earth on 19 December 2025 danger of hitting Earth Although the trajectory of 3I/ATLAS brought it just inside the orbit of Mars, it is...
