Kepler-753 b
Kepler-753 b is a super-Earth orbiting Kepler-753 in the constellation Lyra. It lies about 896 light-years from Earth and was discovered in 2016 using the transit method.
How Big Is Kepler-753 b?
Kepler-753 b has a radius of 1.91 times that of Earth.
Is Kepler-753 b in the Habitable Zone?
The position of Kepler-753 b relative to the habitable zone of Kepler-753 cannot be precisely determined from the available orbital data.
Habitable zone of Kepler-753: 0.296–0.736 AU (conservative: 0.374–0.697 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on Kepler-753 b — one full orbit around Kepler-753 — lasts 5.75 Earth days, shorter than Mercury's 88-day year.
How Was Kepler-753 b Discovered?
Kepler-753 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-753 b?
Kepler-753 b is 896.2 light-years (274.8 parsecs) from Earth. Light arriving here tonight left the planet around the year 1130. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 15,773,120 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-753 b scores 0.29, ranking #1,976 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.

Frequently Asked Questions About Kepler-753 b
Is Kepler-753 b habitable?
Kepler-753 b is not known to orbit within the habitable zone of Kepler-753, and as a super-Earth it is an unlikely candidate for life as we know it.
How far away is Kepler-753 b?
Kepler-753 b is about 896 light-years from Earth in the constellation Lyra. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 15,773,120 years to get there.
How big is Kepler-753 b compared to Earth?
Kepler-753 b has 1.91 times the radius of Earth.
How long is a year on Kepler-753 b?
One orbit around Kepler-753 takes 5.7 Earth days — short enough that 64 of its years would fit into one Earth year.
