Scientists have discovered a six-planet system -- a "super-Earth" and five "mini-Neptunes" which display an exceptionally regular spacing, hinting at how the system may have formed. The planets revolving the star HD 158259 in the Draco constellation were found using the SOPHIE spectrograph.
Researchers found that the K2-18b is probably mostly rocky with a gaseous atmosphere – like Earth, only bigger.
