**Planetary Motion As Observed from Earth**When observing planets from Earth, relative to the fixed background of stars, their movements can be characterized as follows:- **Option A**: Move around Earth from west to east at constant speed.- **Option B**: Usually move from east to west, but occasionally reverse direction for short periods of time.- **Option C**: Usually move from west to east, but occasionally reverse direction for short periods of time.- **Option D**: Move around Earth from east to west at constant speed.- **Option E**: Can only be distinguished from stars by their lack of twinkling.This description helps in understanding how planets shift direction in the night sky, a phenomenon known as retrograde motion, and how they differ in appearance from stars.

Step 1: Define the motion of the earth

The Earth moves in multiple different ways:

The imaginary line that passes through the North and South Poles is known as the Earth's axis. This cycle is in charge of both day and night. One full revolution of the Earth takes about twenty-four hours.
Earth travels in an orbit around the Sun. Seasons change because of this orbital motion. Earth completes one orbit in approximately 365.25 days, which gave rise to the idea of a year.
The tilt of the Earth's axis with respect to its orbital plane is approximately 23.5 degrees. The seasons are caused by the various angles and intensities of sunlight at different times of the year, which are caused by this tilt.
