Step 1
Step 2
Explain why the distance between Earth and Pluto is always changing.
Answer
The distance between Earth and Pluto is always changing due to the following factors:
-
Orbiting the Sun: Both Earth and Pluto are in orbit around the Sun, which leads to varying distances as they travel along their elliptical paths.
-
Different orbital speeds: Earth and Pluto have different orbital speeds and radii, resulting in them being at varying distances from each other at different times.
-
Positions relative to the Sun: Their relative positions with respect to the Sun change continually, further contributing to the changes in distance between the two planets.
A diagram could illustrate the varying positions of Earth and Pluto in their respective orbits.
