Exoplanetary Scratchpad

[SysBP Img]

The most ancient known star to have planets, 375 ly away in Cetus. Star formed 13 BYA. Two planets, one in a 7 day period, another in a 290 day period exist. The star consists of little other than Hydrogen and Helium, and it is a puzzle how the planets could have formed without heavier elements.
