From my answer to a previous question, it was pointed out that Vishwamitra himself attempted to create a parallel world in addition to Brahma's, in which to transport Trisanku in his mortal body.

"'Let there be eternal heaven to Trishanku with his mortal body. Next, as along as the worlds remain, let all of these stars and galaxies I have created also remain eternally in their places as my creation. It will be apt of you all gods to accede to this.' So said Vishwamitra to gods.

"When all the gods are addressed thus they replied the eminent saint Vishwamitra saying, 'so be it! Safe you be! Let all the created objects prevail in their respective places. Those amazing and numerous stars you have created will remain in firmament, but outside the path of stelliform of Cosmic Person. Trishanku will also remain in the circle of stars you created, but upside-down, for Indra's indict cannot be annulled, and he will be gleaming like a star and similar to any celestial.
Brahma's creation can be more or less mapped to scientific accounts of the material world, through careful and minute Shastra analysis. However, my question is, which physical body/bodies represent Vishwamitra's parallel creation, which were destined to "remain eternally in their places"? Assuming they do exist, is it even known to us, where they currently are, and which ones they are? I don't require parallels with modern science. Are there any names of these bodies, mentioned in Shastras?
