Multiple Systems
Just like the name GJ180 d indicates, it is not a single world in its system. The astronomers had discovered two planets orbiting the red dwarf, GJ180 c, and GJ180 b previously. Although astronomers do not know much about these two newfound super-earths, they may learn a lot soon. Because these two planets are not too far from our solar system, they make high targets for research through substantial future investments like James Webb Space Telescope by NASA, which will launch next year.

Feng said that their discovery adds to the list of planets that could be imaged by the telescopes next generation. He said that ultimately they are working towards finding whether the planets orbiting close to stars host life. According to Jeff Crane of the Carnegie Institution, they eventually want to make a map of every world orbiting the nearest star to our solar system, specifically the ones that are possibly habitable.
