Kepler-37d is an extrasolar planet (exoplanet) discovered by the Kepler space telescope in February 2013.[5] It is located 209 light years away,[6] in the constellation Lyra.[5] With an orbital period of 29 days,[1] it is the largest of the three known planets orbiting its parent star Kepler-37.[7]
In 2015, a grant was approved to further expand the Sagan Planet Walk by installing a Kepler-37d station on the Moon 384,500 kilometers (238,900 mi) away.[8]
