Kepler-11, also designated as 2MASS J19482762+4154328,[5] is a Sun-like star slightly larger than the Sun in the constellation Cygnus, located some 2,110 light years from Earth.

These dips in brightness can be interpreted as planets whose orbits move in front of their stars from the perspective of Earth.

[3] In comparison, the Sun is about 4.6 billion years old[7] and has a surface temperature of 5778 K.[8] With an apparent magnitude of 14.2, it is too faint to be seen with the naked eye.

[10][11] The low densities likely result from high-volume extended atmospheres that surround cores of iron, rock, and possibly H2O.

[11][12] The inner constituents of the Kepler-11 system were, at the time of their discoveries, the most comprehensively understood extrasolar planets smaller than Neptune.

In 2014, the dynamical simulation shown what the Kepler-11 planetary system have likely to undergone a substantial inward migration in the past, producing an observed pattern of lower-mass planets on tightest orbits.

Despite this close packing of the orbits, dynamical integrations indicate the Kepler-11 system has the potential to be stable on a time scale of billions of years.
