description Kepler-11e Overview
Kepler-11e is a sub-Neptune exoplanet orbiting the Sun-like star Kepler-11, discovered by NASA's Kepler space telescope. As the fourth of six confirmed planets in this system, it completes an orbit around its host star approximately every 32 days. The planet is distinguished by its exceptionally low bulk density, suggesting it likely possesses a thick hydrogen-helium atmosphere or a significant volatile content. It is frequently studied by astronomers seeking to understand the formation and atmospheric evolution of compact planetary systems.
help Kepler-11e FAQ
How long is a year on Kepler-11e?
Kepler-11e completes an orbit around its host star in approximately 32 Earth days. That short orbital period reflects how closely the planet is packed into the Kepler-11 system.
How was Kepler-11e discovered?
NASA's Kepler space telescope detected Kepler-11e through transits, when the planet passed in front of Kepler-11 and caused a small dip in starlight. The system was confirmed as a six-planet system.
What kind of planet is Kepler-11e?
Kepler-11e is a sub-Neptune, meaning it is larger than Earth but smaller than Neptune. It is the fourth confirmed planet outward from the Sun-like star Kepler-11.
Is Kepler-11e in the same system as Kepler-11b?
Yes. Kepler-11e shares its system with Kepler-11b, c, d, f, and g. The six planets orbit one host star and were studied together because their transit signals revealed a tightly packed planetary system.
