Curios-1

Curios-1
Curios-1 is an otherwise unremarkable solar system. Except for the fact that its three planets all have stable orbits that bring them incredibly close to each other.

Star-
The star is a G-5 yellow star.

Planets-

 * Curios b- Heated by tides, this gas planet makes is the only planet with a circular orbit. Due to the encounters it has, it does not have any major moons.Curios b&c2.jpg
 * Curios b&c.jpgs c- This small, Mars-sized planet, has an almost circular orbit. Except for a small twist due to an encounter with Curios b. And they get really close, close enough that the planet actually gets pulled into one orbit around Curios b. However, the acceleration always sends it back on it's original orbit. Curios b at it closest to Curios c looks about 20x the size of the moon.
 * Curios d- Small and Mercury-sized, it lies for most of it's orbit at Curios b's L4 point. But when Curious c and b converge, their combined gravity brings Curios d into an elliptical orbit that eventually sends it back to the L4 point.
