The Houston Astros are an American professional baseball team based in Houston, Texas. The Astros compete in Major League Baseball (MLB) as a member club of the American League (AL) West division, having moved to the division in 2013 after spending their first 51 seasons in the National League (NL). The Astros have played their home games at Minute Maid Park since 2000.
The Astros were established as the Houston Colt .45s and entered the National League as an expansion team in 1962 along with the New York Mets. The current name—reflecting Houston's role as the control center of the U.S. space program—was adopted three years later, when they moved into the Astrodome, the first domed sports stadium.
