PURPORT

As stated herein, the sun extends for 10,000 yojanas, and the moon extends for twice that, or 20,000 yojanas. The word dvadasa should be understood to mean twice as much as ten, or twenty. In the opinion of Vijayadhvaja, the extent of Rahu should be twice that of the moon, or 40,000 yojanas. However to reconcile this apparent contradiction to the text of the Bhagavatam, Vijayadhvaja cites the following quotation concerning Rahu; rahu-soma-ravinam tu mandala dvi-gunoktitam. This means that Rahu is twice as large as the moon, which is twice as large as the sun. This is the conclusion of the commentator Vijayadhvaja.
