Kepler-1513 b
Kepler-1513 b 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 2016 using the transit method.
How Big Is Kepler-1513 b?
Kepler-1513 b has a radius of 8.59 times that of Earth, or 0.77 times the radius of Jupiter. Its mass is 48.3 times that of Earth, giving it a density of 1.30 g/cm³ — closer to gas planets like Jupiter (1.33 g/cm³).
Is Kepler-1513 b in the Habitable Zone?
The position of Kepler-1513 b 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 b — one full orbit around Kepler-1513 — lasts 160.9 Earth days, between the years of Mercury (88 days) and Earth (365 days). Its orbit is highly elliptical (eccentricity 0.31), swinging dramatically closer to and farther from its star.
How Was Kepler-1513 b Discovered?
Kepler-1513 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-1513 b?
Kepler-1513 b 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 b scores 0.35, ranking #733 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.
