The presently observed expansion rate is consistent with a Sedov similarity solution. This result suggests that the expanding shell of Tycho's supernova has swept up a mass of interstellar gas that is several times greater than its own mass. Individual filaments exhibit significant changes on a time scale of 10 years.
