Ma said, “That’s rough enough for us. Gives us a full afternoon for a walk, and what are we waiting for?”

“For the ceremony, Ma,” I told her. “We got to name the place don’t we? And where did you put that bottle of champagne we were saving for my birthday? I reckon this is a more important occasion than that is.”

She told me where, and I went and got it and some glasses. “Got any suggestions for a name, Johnny? You saw it first.”

“No, sir.”

I said, “Trouble is that Thor and Freda are named wrong now. I mean, Thor is Sirius I and Freda is Sirius II, and since this orbit is inside theirs, they ought to be II and III respectively. Or else this ought to be Sirius O. Which means it’s Nothing Sirius.”

Ellen smiled and I think Johnny would have except that it would have been undignified.

But Ma frowned. “William—” she said, and would have gone on in that vein if something hadn’t happened.

Something looked over the top of the nearest hill. Ma was the only one facing that way and she let out a whoop and grabbed me. Then we all turned and looked.

It was the head of something that looked like an ostrich, only it must have been bigger than an elephant. Also there was a collar and a blue polka-dot bow tie around the thin neck of the critter, and it wore a hat. The hat was bright yellow and had a long purple feather. The thing looked at us a minute, winked quizzically, and then pulled its head back.

None of us said anything for a minute and then I took a deep breath. “That,” I said, “tears it, right down the middle. Planet, I dub thee Nothing Sirius.”
