SB Canto 5

The sun globe, which is a source of heat, extends for 10,000 yojanas (80,000 miles). The moon extends for 20,000 yojanas (160,000 miles), and Rāhu extends for 30,000 yojanas (240,000 miles). Formerly, when nectar was being distributed, Rāhu tried to create dissension between the sun and moon by interposing himself between them. Rāhu is inimical toward both the sun and the moon, and therefore he always tries to cover the sunshine and moonshine on the dark-moon day and full-moon night.

SB 5.24.2, Translation and Purport:

The sun globe, which is a source of heat, extends for 10,000 yojanas (80,000 miles). The moon extends for 20,000 yojanas (160,000 miles), and Rāhu extends for 30,000 yojanas (240,000 miles). Formerly, when nectar was being distributed, Rāhu tried to create dissension between the sun and moon by interposing himself between them. Rāhu is inimical toward both the sun and the moon, and therefore he always tries to cover the sunshine and moonshine on the dark-moon day and full-moon night.

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