Kiana's an Astronaut?

So, we're continuing to read many of the Magic Tree House books that we started prior to Christmas. They were the inspiration for our tree house and often lead to questions. Tonight, we read a chapter from Midnight On The Moon.

Aspen: Daddy, how big is the moon.
Tim: It's big honey... smaller than the earth, but still huge.
Oakley: Is it bigger than me.
Tim: Yeah.
Aspen: It's bigger than our house.
Tim: It's bigger than Tennessee at least.
Oakley: Is it bigger than Pennsylvania?
Tim: Yes.
Aspen: Is it bigger than China?
Tim: Well, that's a country, not a state, but yes. It's probably about that size.
Oakley: So Kiana's an astronaut?

Seriously, that was the leap of logic. Pretty impressive, I say. I mean, I can sort of see how she got there, but it is a pretty funny leap. And no, Kiana (our niece/cousin who was born in China) is not an astronaut, at least not yet. Although a little bird told me that she has started reading the Magic Tree House books with her mom, so we'll see what happens when she reaches book 8.

For those of you wondering (I just did the "research"), the moon's size, in comparison to the earth is as follows:

7.4% of the Earth's surface area
2.0% of the Earth's volume
1.23% of the Earth's mass
