A trinary system consisting of a white dwarf and a short period eclipsing binary formed by two faint red dwarfs: CM Draconis (Aa, Ab and B). Despite that the white dwarf is named „B”, it is the „primary” regarding the mass. CM Dra B in fact has more than double the mass of the two red dwarfs together. Newer researches suggest that the whole triple system is probably around twice as old as the solar system and the white dwarf was a star bigger, brighter  and more massive than the sun today.

Based on these facts, I created a purely hypothetical small and cold planet, at the outer edge of the complex habitable zone, circling around the barycenter of the binary red dwarf system.

The planet is a barren desert, the once existing water has turned into ice billions of years ago, forming a landscape similar the antarctic dry valleys on earth. Over the eons the atmosphere thinned out by evaporation and dissipation trough radiation.

The combined stellar flux of the two host stars is about a fifth the earth receives from the sun and it’s approximately as bright as an overcast winter day on earth. Under these conditions the white dwarf is visible at daylight, about as bright as Venus in crescent in the earth sky.

Related to descriptions of planets around red dwarfs I found this:

„…At this point I must emphasize that the term „red dwarf” is misleading, as are color names for most kind of stars. We would not see a dull crimson ember..

Our star is certainly less brilliant than Sol. You could look straight at it for a little bit longer without suffering permanent eye damage, but only a little bit, and you wouldn’t want to. Its light has a yellowish tinge and at the distance of our imaginary planets there is significantly less than Earth gets, but human vision is so adaptable that ordinarily this won’t make any important difference. …”

Very nice! I must say you're getting very good at manipulating Terragen!

The research that you compiled for your piece really fires the imagination as well! Congradulations and well done! =)

Thank you for your appreciation.
Well, "skill comes with practice" we say, but I'm still at the beginning and mostly learning by doing and sometimes needing much time until the render fits (more or less) my ideas.

Nice work on the image and backstory writeup!

The search for exoplanets is going to heat up even more once the James Webb space telescope goes up...
