Beautiful rendering of a planet orbiting a 10⁴ solar mass black hole If you look closely you can see the reflection of the black hole off the planet's surfacepic.twitter.com/vdsTWnI7ql

Would the accretion disc be on a fixed plane at the “equator” or would it be relative to the observer?
-
As I understand it the accretion disk should appear to have a tilt, which he did account for it’s just hard to tell cause it’s so close

Shouldn't the color of the planet change as it orbited due (gravitational) redshift?
-
well if it’s a circular orbit it’s motion is along constant curvature, you might see a Doppler blue/red shift depending on the orbital speed though

AFAIK this rendering is not correct. One point: The reflection of the accretion disc is always from the bottom. There should no orbit around the black hole on a parallel plane with respect to the accretion disc. The orbits and the plane should intersect.

It only doesn’t allow light to escape once its past the event horizon. The light you’re seeing is from an accretion disk of material around the black hole but not yet pulled past the event horizon. It’s glowing because it’s being subjected to such extreme stresses.

It's a great gif. Wouldn't the radiation from the accretion disc also tear the planet apart/vapourise it over time? I mean, the disc would not be stable and would have the same effect as a pulsing red giant, as additional dust/gas flowed in on occasion?
