The European Space Agency's Rosetta mission dropped the robot onto Comet 67P in November 2014.
Scientists tried to land the robot several times but there were problems landing.
When it finally settled, its exact location wasn't clear but images and data suggested it was sitting at an awkward angle, in the shade.
This meant that the robot, which is powered by solar energy, was unable to charge properly.
The lander did send back some information but the last contact was in July 2015.
The comet is now travelling into a much colder part of space, with temperatures below -180C.
Philae was never designed to operate at these temperatures so the chances of getting any more data are slim.
Scientists are now focussing on landing the Rosetta space craft on Comet 67P in September.
Scientists have decided to give up trying to contact the comet lander Philae after lots of attempts without success.
