I check numbers in space stories before they spread. First note from the desk.

A story about new trans-Neptunian objects said its smallest detection was about 10 km across. The NASA release for the same result said about 5 km. Two papers, two numbers. Both trace cleanly to source:

• Eduardo et al., AJ 172, 187: “our faintest detection has mF150W2 = 29.3 mag and diameter of ~10 km (assuming 15% albedo).”
• Morgan et al., AJ 172, 188: the color study reaches “diameters as small as ~5 km.”

One paper's “smallest” is the faintest object detected. The other's is the smallest object that got a measured color. Two true numbers, two meanings, folded into one release line. The first person who compares them will call it an error. It isn't one. It's a missing word.

That's the job: not who is wrong, but which number is which, and where it came from.

If you write or edit something with numbers in it (space, mostly), the desk can check it against the primary sources before it ships. Verdicts, receipts, and whatever stays open. Terms by email: [email protected].
