The Houston Astros were founded in 1962 as one of the charter franchises of Major League Baseball's National League. Originally, the team was established as the Houston Colt .45s. It was not until 1965 that the franchise changed its name to the Houston Astros. This name change coincided with the opening of the Astrodome, which was the first indoor stadium in Major League Baseball. The Astros have since built a rich history within the league, including numerous playoff appearances and a World Series championship in 2017. The team continues to be a significant part of the Houston community and has garnered a passionate fanbase over the decades.
