Mercury
Mercury is the smallest planet in the solar system. It has a radius of 1,516 miles and is nearly one-third the size of Earth. In fact, its size is only slightly larger than that of Earth’s Moon.
Mars
Mars comes second in the order of the smallest to largest planets. It is also the fourth planet in the solar system in terms of distance from the Sun while being situated quite close to Earth in relative terms.
Venus
Venus is the third smallest planet in the solar system and is the second planet in terms of its location near the Sun. This planet takes 225 Earth days to orbit the Sun, which means that one year on Venus is equivalent to 225 Earth days.
Earth
Earth is the third closest planet to the Sun. It has a radius of 3,959 miles, making it slightly larger than Venus. Earth usually takes 365 days to complete a single orbit around the Sun, making this time period equivalent to one year on Earth.
Neptune
Neptune is the fourth-largest planet in the solar system and is the eighth and farthest planet from the Sun. It has a radius of 15,299 miles, making it 3.9 times larger than Earth.
Uranus
Uranus is the third-largest planet in the solar system and is the seventh planet in terms of distance from the Sun. It has a radius of 15,759 miles, making it slightly larger than Neptune but nearly four times larger than Earth.
Saturn
Saturn is the second-largest planet among the other planets in the solar system. It is also the sixth planet from the Sun. Saturn has a radius of 36,184 miles, making it nearly nine times larger than Earth.
