YES. A small circle is simply a circle around the earth that does not fly over the direct opposite place on earth that a plane took off from. A great circle goes full circumference of earth, where a small circle does not. Being a circle they both fly in a constant direction.
27 1/3 days to orbit the earth however the number of days between a full moon and the next full moon is 29 1/2 days.
A full revolution around Earth takes about 27 1/2 days. A full cycle (from full moon to full moon for example) takes a bit longer: 29 1/2 days.
90° is 1/4 of a full circle, so 1/4 of a year. Taking 1 year = approx 365.24 days gives 91.31 days.
It takes 365.24 days for the Earth to go around the Sun one time.
It takes Mercury about 59 Earth days to complete one full rotation on its axis. This means that a day on Mercury (one full rotation) is equivalent to 59 Earth days.
A lunar cycle is the time it takes for the moon to make a full revolution around the Earth. It takes about 29.5 days.
A full moon appears as a dark circle in the night sky on certain days, caused by the shadow of the Earth falling on it during a lunar eclipse.
The moon revolves around earth once in 27.32 days. It displays a full cycle of phases in 29.53 days.

The moon's revolution around the Earth takes approximately 27.3 days, which is also known as its sidereal period. This is the time it takes for the moon to complete one full orbit around the Earth.
It takes Mercury 88 Earth days to make one full orbit around the sun.
