This is system is nuts - six out of the seven satellites around this planemo are incandescent (> 700°C). How does this even happen? The main light source for the system keeps switching around as the satellites move relative to eachother! Ironically the hottest body is actually pitch black and doesn't glow at all (but does cast light). The location is RS 1773-2742-8-333341-10 in the Arp 148 galaxy.
The primary is 6.4MJ, the system is 5.4 billion years old, the orbital eccentricities aren't that extreme (0.018, 0.024, 0.012, 0.017, 0.016, 0.160 (for the frozen moon), and 0.276 for the outer ice giant). Surely that's not enough to tidally heat all these bodies to incandescence?! The outer two satellites are highly inclined to the inner system but I don't think that should increase the heating on those. The info panel doesn't say what's causing the heating either, it just says the air temperature is ridiculously high while the exosphere temp and greenhouse temp aren't anywhere near enough to heat it that much (I think there needs to be a 'tidal heating temperature' listed too?).
