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.
Not surprisingly, there is a species of marmot that is of endangered status here in North America. It is the Vancouver Island Marmot of British Columbia. A population of about 300 individuals in the mid 1980âs has dwindled to about 100 currently.
