Distances expressed in fractions of a parsec usually involve objects within a single star system. Messier 82 has a starburst core of about 600 parsec in diameter. Orion B is about 1370 light-years (420 parsec) distant to Earth. This corresponds to the small-angle definition of the parsec found in many contemporary astronomical references. To the nearest meter, the small-angle parsec corresponds to . A number of solutions to the final parsec problem have been proposed. By the year 2006 "Thousand Parsec" had not reached the envisioned goals. A parsec is a unit of distance. Dramis later wrote "Parsec" for the TI-99/4A. Existing benchmarks include SPLASH-2, PARSEC, and COSMIC for heterogeneous systems. The central cubic parsec around Sagittarius A* contains around 10 million stars. Sigler has been a runner up in both the 2006 and 2007 Parsec Awards. His podcast "Writing Excuses" has won a Hugo Award and three Parsec Awards. It is useful to 100 Mpc (parsec). As the parsec is a unit of distance, not time, different explanations have been provided.
