HIP 63835 CD 1 is one of the most strangest planets i have stumble my joyrneys! It is normal class 3 gas giant but what make it special no sun light or any light ever hit the planet it is comletely dark planet! Not even close by (600ls away) giant O class star light never reach the planet why? Possible because it's orbiting two black holes only 8.5ls distance so my theory is those black holes capture all light i don't now is it the reason but could be most logical reason because even light can't escape black holes also how it possible that planet even can be exist!?!? System HIP 63835 is close the habitat space only 275ly from sol so go check it out
