It was found using the transit method, in which the dimming effect that a planet causes as it crosses in front of its star is measured. Kepler-62e is most likely a terrestrial planet in the inner part of its host star's habitable zone.[1]

Given the planet's age (7 ± 4 billion years), stellar flux (1.2 ± 0.2 times Earth's) and radius (1.61 ± 0.05 times Earth's), a rocky (silicate-iron) composition with the addition of a possibly substantial amount of water is considered plausible.[1] A modeling study accepted in The Astrophysical Journal indicates the planet is likely to be completely covered by ocean.[2]
