Lunar Sidereal and Synodic Periods. The Moon's sidereal orbital period (the sidereal month) is ~27.3 days; this is the time interval that the Moon takes to orbit 360Â° around the Earth relative to the fixed stars. The period of the lunar phases (the synodic month), e.g. the full moon to full moon period, is longer at ~29.5 days.
While there are several species of marmots in North America, our woodchuck is found mostly in the eastern United States and across much of southern Canada. In New England, woodchucks inhabit both urban and suburban yards, fields, meadows, woodland clearings, and we see them frequently in grassy areas along highways.
Rodents. Weighing up to a thick 14 pounds, and sometimes measuring more than 2 feet long, the marmot is a signature rodent in the Alps. It hibernates from October through March and emerges in spring from a network of burrows to begin foraging in mountain meadows.
