K2-187, also known as EPIC 212157262, is a Sun-like star in K2 Campaign 5. It is very close in size and temperature to the Sun, and has a system of four confirmed exoplanets ranging between 1.4 R🜨 and 3.2 R🜨. The innermost planet takes just 18 hours to orbit its star, while the outermost planet orbits every 2 weeks.[2]
