Based on recent 2025-2026 astronomical data, the phrase "3i atlas turned into 10000 objects" refers to an estimation by scientists at the Southwest Research Institute (SwRI) that at least 10,000 interstellar objects (ISOs) are likely passing through our Solar System inside Neptune's orbit at any given time.

3I/ATLAS (officially C/2025 N1) is merely the third of these objects discovered, serving as a catalyst for a new understanding of how common these interstellar visitors are.

Here is the explanation of the science behind 3I/ATLAS and the "10,000 objects" estimation:

They are coming to Earth.
