The name comes from Kurt Vonnegut's novel Cat's Cradle
"... wherein Borasisi
, the sun, held Pabu
, the moon, in his arms, and hoped that Pabu
would bear him a fiery child.
"But poor Pabu
gave birth to children that were cold, that did not burn; and Borasisi
threw them away in disgust. These were the planets, who circled their terrible father at a safe distance.
"Then poor Pabu
herself was cast away, and she went to live with her favorite child, which was Earth. Earth was Pabu
's favorite because it had people on it; and the people looked up at her and loved her and sympathized."
