The last two times this event happened, astronomers attempted to measure the length of the Astronomical Unit, which is the mean distance between Earth and the Sun. To do this, they carefully recorded where Venus appeared on the Sun as viewed from two locations on Earth. This relative change in an object's observed position is called parallax. Based on what you already know about parallax, how is the change in position of Venus related to the actual difference in location on Earth?

A. The closer the Earth locations, the farther apart the Venus locations appear to be.

B. There is no relationship between the distance between Earth locations and the distance between Venus locations on the Sun.

C. The farther apart the Earth locations, the closer together the Venus locations appear to be.

D. The farther apart the Earth locations, the farther apart the Venus locations appear to be.

A. The closer the Earth locations, the farther apart the Venus locations appear to be

Explanation:

Venus is the closest planet to the earth and is most similar in size but the nearness to the plant depends on the orbit as the planets travel in an ellipse around the sun and thus the distance among them is constantly shifting and changing. Venus takes about 224 days to travel around the sun. Thus the distance from the venus form the earth is about 223 million km.
