Kepler-1513 c
Kepler-1513 c is a cold gas giant orbiting the G V star Kepler-1513 in the constellation Lyra. It lies about 1,139 light-years from Earth and was discovered in 2023 using the transit timing variations method.
Is Kepler-1513 c in the Habitable Zone?
The position of Kepler-1513 c relative to the habitable zone of Kepler-1513 cannot be precisely determined from the available orbital data.
Habitable zone of Kepler-1513: 0.658–1.563 AU (conservative: 0.833–1.482 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on Kepler-1513 c — one full orbit around Kepler-1513 — lasts 841.4 Earth days, longer than an Earth year. Its orbit is mildly elliptical (eccentricity 0.13).
How Was Kepler-1513 c Discovered?
Kepler-1513 c was discovered in 2023 using the transit timing variations method, with observations from Multiple Observatories.
Transit timing variations reveal a planet through its gravitational tug on a sibling planet, which makes that sibling's transits arrive slightly early or late. The pattern of these deviations betrays the hidden planet's mass and orbit.
How Far Away Is Kepler-1513 c?
Kepler-1513 c is 1,139.1 light-years (349.2 parsecs) from Earth. Light arriving here tonight left the planet about 1,139 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 20,048,160 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-1513 c scores 0.28, ranking #2,346 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.
