According to this quote from the Brahma-saṁhitā, there are not only infinite numbers of planets, as confirmed by the Russian astronomer, but there are also infinite numbers of universes. All these infinite universes with their infinite planets within are floating on and are produced from the Brahman effulgence emanating from the transcendental body of Mahā-Viṣṇu, who is worshiped by Brahmā, the presiding deity of the universe in which we are residing.
The Russian astronomer also confirms that all the planets—which are estimated to be not less than one hundred million—are inhabited. In the Brahma-saṁhitā there is indication that in each and every one of the infinite number of universes there are infinite numbers of variegated planets.
