Kepler-36b orbits its star every 14 days at an average distance of less than 11 million miles. Kepler-36c orbits the star every 16 days at a distance of 12 million miles.

However, since it orbits once every 0.84 days, Kepler-10b is more than 20 times closer to its star than Mercury is to our sun and not in the habitable zone.

Their orbits are also different. While Kepler circled the Sun at a similar distance to Earth, Tess goes around the Earth on an elliptical orbit.

NASA's Kepler planet-hunting probe has spotted a system where two giant planets are locked in constantly changing orbits — with a super-Earth potentially pinned down in the crossfire ...

The retired Kepler space telescope helped NASA and astronomers discover thousands of exoplanets, some, perhaps, with the capacity for life.

This is an important component of the new Kepler catalogue, and it led the researchers to some new conclusions. The main one concerns the nature of planetary orbits in multi-planet systems.

Explore Kepler observatory discoveries revealing a unique solar system of six tightly packed planets orbiting a sun-like star.

Meet exoplanet Kepler-1649c — it’s the same size as Earth, and its distance from its sun is just right for life — and that may NOT be a good thing. Sitting roughly 300 light years from Earth ...

Just as Earth orbits the Sun, Kepler-1649c orbits a red dwarf star — but a year on the planet is equivalent to just 19.5 days on Earth.

With 10 times the mass of our planet, and spending only part of its orbit in the habitable zone, Kepler-725c is very different to Earth.

NASA scientists today announced a new planet called Kepler-16b that orbits two stars, a discovery that seems to bring to life the fictional Luke Skywalker home of Tatooine with its double sunset.
