Kepler-1494 b
Kepler-1494 b is a sub-Neptune orbiting Kepler-1494 in the constellation Lyra. It lies about 4,193 light-years from Earth and was discovered in 2016 using the transit method.
How Big Is Kepler-1494 b?
Kepler-1494 b has a radius of 3.07 times that of Earth.
Is Kepler-1494 b in the Habitable Zone?
The position of Kepler-1494 b relative to the habitable zone of Kepler-1494 cannot be precisely determined from the available orbital data.
Habitable zone of Kepler-1494: 0.681–1.611 AU (conservative: 0.863–1.527 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on Kepler-1494 b — one full orbit around Kepler-1494 — lasts 91.1 Earth days, between the years of Mercury (88 days) and Earth (365 days).
How Was Kepler-1494 b Discovered?
Kepler-1494 b was discovered in 2016 using the transit method, with observations from Kepler.
The transit method watches a star for the tiny, regular dip in brightness that occurs when a planet crosses in front of it. The depth and timing of these dips reveal the planet's size and orbital period.
How Far Away Is Kepler-1494 b?
Kepler-1494 b is 4,192.7 light-years (1,285.5 parsecs) from Earth. Light arriving here tonight left the planet about 4,193 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 73,791,520 years to make the journey.
Earth Similarity Index
The Earth Similarity Index (ESI) scores how physically similar a planet is to Earth, from 0 to 1, based on radius, density, escape velocity and surface temperature. Kepler-1494 b scores 0.35, ranking #768 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.
