Uru allegedly is the second planet orbiting Aldebaran, or at least that's what Martin Wiesengrün was told when he met beings that claimed to be from there.
Uru would be the second planet circling Aldebaran. Current estimates locate Aldebaran at 65.1 LY away. Older estimates situate it approx. 60 LY away, which is in line with the 59 LY Martin Wiesengrün mentions.
Note that there are - thus far unconfirmed reports - of a possible brown dwarf companion, in which case Aldebaran would be a binary system.
Allegedly the natives call their sun Raula.
Its inhabitants look like regular humans.
This is a contactee case that involved Martin Wiesengrün (a pseudonym), and that was investigated by Wendelle Stevens.
The contact happened in the summer of 1957 in Glowe, on Rügen island, off the Baltic coast, in the former DDR. He was 15 at the time. He was invited aboard their ship where he stayed for 3 days to get an education which they had planned for him.
On board he met several species, most of which were from Arian.
One of the things they told him was that they had lived on Earth - in what is now Greenland - and were present 65 million years ago, when an asteroid hit. They also mention Atlantis.
