Our solar system has a new visitor. This celestial traveller, dubbed 3I/ATLAS, is not from around here. It is only the third object ever confirmed to have come from the vast emptiness of interstellar space. Its path is not a gentle loop around our Sun but a hyperbolic trajectory—a clear cosmic sign that it is just passing through.
As astronomers trace its path backward, the conclusion is clear: 3I/ATLAS began its journey far beyond our Sun's influence, wandering the galaxy before tumbling into our neighbourhood. This discovery offers a rare chance to study material from another star system, a cosmic messenger carrying secrets from the void. But with any new visitor hurtling through space, the first question is always the same: is it coming our way?
