Found a hostile planet which qualifies:

Eissentam galaxy, of course.

Also, be careful. It has aggressive sentinels waiting at every corner. So best to land, get out of the ship, feel extremely hot and get back into the cosy ship. Leave and hope no one saw that.

Will do. If anyone finds these ones, post a planetary address, please. Can't promise I'll use it, but I don't want to fail this expedition. So maybe. 😄

Am looking primarily in green systems. There's a toxic planet in almost all of them.
