K2-58 (also designated as EPIC 206026904) is a G-type main-sequence star in the constellation of Aquarius, approximately 596 light-years from the Solar System. The star is metal-rich, having 155% of the Solar abundance of elements heavier than helium.[3] The star is located in a region where a hypothetical observer in the K2-58 system can see Venus transiting the sun.[5]
