Phase Rotation | Polyphase AC Circuits | Electronics Textbook
REVIEW: Phase rotation, or phase sequence, is the order in which the voltage waveforms of a polyphase AC source reach their respective peaks . For a three-phase system, there are only two possible phase sequences: 1-2-3 and 3-2-1, corresponding to the two possible directions of alternator rotation. www.allaboutcircuits.com

Stars - Science@NASA
Astronomers call stars that are stably undergoing nuclear fusion of hydrogen into helium main sequence star s. This is the longest phase of a star's life. The star's luminosity, size, and temperature will slowly change over millions or billions of years during this phase. Our Sun is roughly midway through its main sequence stage.
