By using a more accurate method for estimating the average distance between two orbiting bodies, we find that this distance is proportional to the relative radius of the inner orbit. In other words, Mercury is closer to Earth, on average, than Venus is because it orbits the Sun more closely.
How is Mercury closest to all planets?
It considers the distance between two planets to be the average distance between all points along their respective orbits. Thus, Mercury’s orbit doesn’t take it very far from the sun, but Venus gets much farther away from Earth during its orbit. … Therefore, Mercury is closer.
What is closest planet to Earth?

Does Mercury rotate?
Mercury rotates slowly. One rotation takes nearly 59 Earth days to complete. However due to an orbital-rotational resonance ratio of 3:2, a fictitious observer on Mercury would see that a solar day from noon to noon would take about 176 Earth days to complete.
