* Distance: The Earth's orbit around the Sun is not perfectly circular, it's slightly elliptical. This means the distance between the Earth and Sun varies throughout the year.

* Average Distance: The average distance from Earth to the Sun is approximately 93 million miles (150 million kilometers). This is often referred to as an Astronomical Unit (AU).

* Closest Point (Perihelion): Earth is closest to the Sun in early January, at about 91.4 million miles (147.1 million km).

* Farthest Point (Aphelion): Earth is farthest from the Sun in early July, at about 94.5 million miles (152.1 million km).

* Displacement: Displacement refers to the change in position from the starting point to the ending point. Since Earth completes a full orbit around the Sun in one year, it returns to its original starting position. Therefore, its displacement over one year is zero.

Key Point: While Earth travels a great distance around the Sun, its displacement is zero because it returns to its starting point after one full orbit.
