Pisces-Eridanus stellar stream
Pisces-Eridanus stellar stream is a close stellar stream, between 80 and 226 parsecs away, and stretching 120° across the sky, an open cluster that was stretched apart by past gravitational interactions. By analysis of the highest mass member stars, it is estimated to be only 120 million years old, a similar age to the Pleiades.[1]
Stars
The stream includes at least 5 naked eye stars: Lambda Tauri at 3.5 magnitude star, 148 parsecs, Omicron Aquarii at 4.7 magnitude, 134 parsec distance, 106 Aquarii at 5.2 magnitude, 114 parsec distance, 108 Aquarii at 5.2 magnitude 98 parsec distance, Tau1 Aquarii at 5.7 magnitude, 97 parsec distance and Nu Fornacis at 4.7 magnitude and 114 parsec distance.
gollark: Or would, if I made mistakes, which I do not.
gollark: Me too! I like to focus on messing up the higher level bits.
gollark: This is due to the recently discovered isomorphism between you, Tux1, and the BL602 microcontroller from Bouffalo Labs.
gollark: Well, you would.
gollark: Or raw processor microcode some days, for that performant performance.
