The smallest Black Hole I've run across 18.68km, about 1.88840612 × 1025 kilograms and of course has an extremely high density. Super massive Black Holes have very low densities, almost that of water.

A miniature Titan, only 3911km diameter. Not sure what makes a Titan a Titan.

A planetary characteristics and atmosphere similar to the actual Titan, I guess.

Planets with liquid on their surfaces are an interesting breed, and in the case of Titans they have seas of hydrocarbons rather than water.  So they tend to be cold and with atmosphere.

What star? :)

That is a very very small titan :D

Liquid hydrocarbons ;)

Also, the titan in Gnargenox's post is "Frozen", which means -175 Celcius or colder, and the titan has a simi-major axis of 0.09 AU.
What does it orbit around? A brown dwarf?

I'm currently hunting for the fastest-rotating rocky planet I can find. So far, the fastest I've found is RS 8591-173-1-5-111 1,
which rotates in 8 hours and 46 minutes:

I love that the planet has approximately 1300 times the atmospheric pressure of Earth, 14 times the atmospheric pressure of Venus, and you can still se the surface.

I also love that it is "Scorched", and would still be that without greenhouse effect, with a semi-major axis of 31.18 AU. And it is a planet, so probably no extreme tidal heating. What does this orbit around? A O star?

It orbits an O6.5V main-sequence star of 33.17 solar masses and 6855.6 solar luminosities. Its semimajor axis is 31.18 AU, with a period of 30.23 years. Its orbit is actually a fair bit mor eccentric than Earth's, at 0.067, but orbiting that far out, I agree: I don't think tidal heating comes into play. Some quick calculations suggest its temperature is plausible, especially if you factor in the 75% CO2 atmosphere (with a partial pressure of 977 atmospheres).

On and off, for the last year or two, I've been searching for the hottest procedural planet in SpaceEngine.

This is RS 0-7-936228-949-7-0-0-15 B2. It's a scorched desert at 1,440 C and a somewhat Venus-like atmosphere of water vapor and carbon dioxide. It orbits fairly close to a 10-solar-mass blue supergiant.

The dimmest, most difficult to see rings around a planet I've ever barely been able to see. I mean I could NOT find any angle with any background that showed them better than this!

RS 7349-409-8-3511004-49 is a triple star system including 6 planets with life, out of 27 planets total. :D
The system is located in the galaxy NGC 6045A.
