System 204
System 204
This star system is particularly interesting. It is a binary of a spectral-type K orange dwarf star and a G yellow dwarf. However, both
stars evidently began as solitary systems which later collided and merged. This would have disrupted the orbits of some of the planets
of each parent star. A very hot M-class planet and a hot gas giant are spiralling into the G-class star, the innermost M-class planet is
slowly evaporating. A number of rogue planets have been expelled from both star systems, complete with moons, though some of
expelled planets may have associated with one-another gravitationally as they were expelled. Collisions between planets may account
for some of the very high surface temperatures of some of the planets in this system. The K-star's planets seem to have faired better,
possibly because two outer orbiting supergiants may have absorbed collisions, perhaps capturing some of the perturbed planets as
new satellites.

These supergiants may have protected the two innermost planets of the K-star, which is fortunate as both lie in the habitable zone of
their parent star and both are class M planets. However, the innermost of the two is at the lighter end of the m-class spectrum and has
a negligible atmosphere (planet 16), resulting in wide fluctuations of temperature, even though the mean temperature is tolerable. The
remaining planet (planet 17) has a thin but significant atmosphere and we would weigh less than half our normal weight on the planet's
surface (g = 0.46). It's mean temperature is ideal for life. Furthermore, its spectral signature is strong for atmospheric oxygen,
suggesting that it might harbour photosynthetic life-forms.

Science Officer Recommendation: send a small landing team equipped with oxygen concentrators to explore the surface of planet 17.
