An Earth-sized exoplanet, Kepler-1649c, was identified by NASA's Kepler space telescope as the system's outermost planet, circling a red dwarf star, Kepler-1649, in its habitable zone. It is situated in the constellation Cygnus and is roughly 301 light-years (92 pc) away from the surface of our planet (Andrew, 2020). K2 Science Office director Jeff Coughlin called it the "most Earth-like planet" identified by the Kepler Space Telescope as a "similar planet to Earth."

The plane problem on sliding down of an initially resting heavy flexible inextensible chain from a horizontal table with a rounded edge in the presence of dry friction is considered. An analytical formula for tension of the chain along its total length is found. Several phase portraits of the problem are depicted.
