| Today I just found a quite impresive place. It's a warm, orange selena, orbiting a brown dwarf at just 7 times the Earth-Moon distance. But that's not its most interesting feature: this brown dwarf orbits a Sun-like star, at enough distance to maintain this, its only planet, but also close enough for the planet to be illuminated by both stars. This leads to the following:
If that isn't curious enough, let time pass until both stars illuminate the planet from both sides. The star seen on both pictures is the 3rd of this system, but located much farther away:
The views, from the planet's surface, are also amazing. At 'just' 440 K, looks like a place one could have a walk:
At a certain point of the year, you can see both main stars together. The luminosity difference is remarkable:
And, finally, a closer look to that brown star:

| This is actually quite common.
This selena is lighted by three different stars, a yellow dwarf, a red dwarf and a brown dwarf.
I love this shot.
