Star system, 2,100 light-years
Kepler-11 and its six planets
Kepler-11 b is an exoplanet 1.8 times Earth's width, 2,100 light-years away, orbiting closer to its star than the habitable zone we compute for it.
Kepler-11 is a star of spectral type the table does not record, 2,100 light-years from us, with six known planets. This page takes them one at a time.
Drawn at the system's own scale, every orbit from the Archive's numbers.
What is measured, what is computed, what is imagined.
measured The period, and where the table says so the width and the mass, by the method named in each section.
computed Anything marked computed: the size of an orbit where Kepler's third law corrects the table, the temperature of a bare ball at that distance, the starlight received, and the habitable zone.
imagined The picture is an artist's impression. Nobody has seen the surface of a planet of another star: its colour, clouds and land are not known, and the share picture says so in its corner.
