Which planet is the closest to the Sun?

Mercury is the closest planet to the Sun in our solar system. It orbits at an average distance of about 57.91 million kilometers (approximately 36 million miles) from the Sun. This proximity gives Mercury extreme temperature variations, with extremely hot days and bitterly cold nights.

The other planets listed have orbits that are farther from the Sun. Venus, for example, is the second planet from the Sun and takes a longer time to complete its orbit. Earth comes third, being the third planet from the Sun, while Mars is the fourth. Understanding the order of the planets in relation to the Sun not only highlights Mercury's closest position but also reveals the unique characteristics and conditions of each planet based on their distance from the Sun.
