This type of orbit is a special case of the Polar orbit.  Like the polar orbit, the satellite travels from north to the south poles as the Earth turns underneath. In a sun- synchronous orbit the satellites passes over the same part of the Earth at roughly the same local time every day. This can make communication and different types of data collection very convenient and accurate. Sun-synchronous orbit’s orientation links and relates with the Sun, allowing us to collect very accurate weather predictions and other important information and data. For example, a satellite in a sun-synchronous orbit could measure the air quality of Ottawa at the afternoon.  Most of these satellites orbit our planet 15 to 16 times per day.​
