'''The Hyades''' (also known as Melotte 25 or Collinder 50) is the nearest open cluster to the Solar System and one of the best-studied star clusters. The age of the cluster is estimated to be about 625 million years old. From the perspective of observers on Earth, the '''Hyades''' Cluster appears in the constellation Taurus, where its brightest stars form a "V" shape along with the still brighter red giant '''Aldebaran'''. However, '''Aldebaran''' is unrelated to the '''Hyades''', as it is located much closer to Earth (hence its apparent brightness) and merely happens to lie along the same line of sight. | '''The Hyades''' (also known as Melotte 25 or Collinder 50) is the nearest open cluster to the Solar System and one of the best-studied star clusters.

This is an extensive stellar association visible in the constellation of Canis Major. The concentration of stars here are scattered over a wide area, and thus difficult to pinpoint on the map. | This is an extensive stellar association visible in the constellation of Canis Major.

'''Collinder 140''' is an open cluster that contains approximately 40 stars and is estimated to be some 20 million years old. Its central star, H'''IP 38064,''' features unusually large stellar objects with rings, including an M-class star, a class L-dwarf and two Y-class dwarfs. The O-class primary star lights up the rings with vivid blue and purple colors. | |||
The nearest two planets are in inside the star's corona, and in close proximity to each other, causing spectacular views. Planet 2 contains a tourist beacon with information on the original discovery of this area. Commanders should take great care when landing on planet 2; high gravity is present, and proximity to the star may cause overheating. | |||
