A Massive open online course (MOOC) is a course where the participants are distributed and course materials also are dispersed across the web. This is possible only if the course is open, and works significantly better if the course is large. The course is not a gathering, but rather a way of connecting distributed instructors and learners across a common topic or field of discourse.
