It’s hard for our body to tolerate extreme temperature whether it is too hot or too cold, anyone who tried to have an adventure crossing Sahara or climbing Mount Everest would know that well. But, imagine living on a planet that has erratic seasonal variation, you would hardly know whether it is summer or winter and you won’t even survive. This is the situation of the planet that NASA’s planet-hunting Kepler space telescope discovered.
This illustration shows the unusual orbit of planet Kepler-413b around a close pair of orange and red dwarf stars.
The new planet, which is labelled as Kepler-413b is located in the constellation Cygnus which is 2,300 light-years (2.17592153 × 1016 kilometers) away.
The planet has a rotational precession of 30 degrees over 11 years along its axis as compared to Earth, which is 23.5 degrees over 26,000 years. The short precessional period of the planet Kepler-413b is responsible for rapid and unstable seasonal variation. Also, the plane of its orbit is tilted 2.5 degrees with respect to the plane of the star pair’s orbit, this is why its orbit appears to wobble.
Kepler-413b orbits too close to the stars, its temperatures are too high for liquid water to exist even during the seasonal variation. The planet is uninhabitable.
