Srimad Bhagavatam Canto 05, Chapter 22, Text 17

SB 5.22.17

tata uttarasmad rsaya ekadasa-laksa-yojanantara upalabhyante ya eva lokanam sam anubhavayanto
bhagavato visnor yat paramam padam pradaksinam prakramanti.
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
Situated 8,800,000 miles above Saturn, or 20,800,000 miles above earth, are the seven saintly sages, who are always thinking of the well-being of the inhabitants of the universe. They circumambulate the supreme abode of Lord Visnu, known as Dhruvaloka, the polestar.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
Srila Madhvacarya quotes the following verse from the Brahmanda Purana:
jñananandatmano visnuh
 sisumara-vapusy atha
urdhva-lokesu sa vyapta
 adityadyas tad-asrita
“Lord Visnu, who is the source of knowledge and transcendental bliss, has assumed the form of Sisumara in the seventh heaven, which is situated in the topmost level of the universe. All the other planets, beginning with the sun, exist under the shelter of this Sisumara planetary system.”
Thus end the Bhaktivedanta purports of the Fifth Canto, Twenty-second Chapter, of Srimad-Bhagavatam, entitled “The Orbits of the Planets.”
