This suggests that 3I/ATLAS is more massive than the other two interstellar objects, 1I/`Oumuamua and 2I/Borisov by 3–5 orders of magnitude, constituting a major anomaly. Given the limited reservoir of heavy elements, we should have discovered on the order of a hundred thousand interstellar objects on the 0.1-kilometer scale of 1I/`Oumuamua before finding 3I/ATLAS, yet we only detected two interstellar objects previously.

Momentum conservation implies that 3I/ATLAS must be massive in order not to be pushed back by the flow of material from its warmed Sun-facing side. I assumed a high collimation of the evaporated materials because the glow of scattered light in the Hubble Space Telescope image was twice longer towards the Sun than it is wide, at a viewing angle of 10 degrees. Since [1/sin(10 degrees)]=5.8, the elongation in the plume ahead of 3I/ATLAS must have been 10 times longer than it is wide. This jet-like structure suggests a high collimation.
