Mercury, which is the closest planet to the Sun, is 36 million miles from the sun, and Neptune, the eighth planet from the Sun, is approximately 2,790,000,000 miles away. The rest of the planets fall in between that range.
The Earth is about 93 million miles away from the star, or 1 astronomical unit. This makes it the third planet from the Sun. Venus, the second closest planet to the Sun, is about 68 million miles from the Sun, or 0.73 AU. Mars, the fourth closest planet to the Sun, is about 128 million miles from the star, or 1.38 AU. Jupiter, a gas giant and the largest planet, is the fifth planet from the Sun. It is about 484 million miles from the Sun, or 5.20 AU. Saturn, the sixth closest planet to the Sun, is about 887 million miles from the Sun, or 9.54 AU. Uranus, the seventh planet, is about 20 AU from the star, or approximately 1,860,000,000 miles.
Astronomers have demoted Pluto to a dwarf planet, but it was once classified as the ninth planet from the sun. Pluto is about 4.6 billion miles from the Sun, or 49 AU at aphelion. Pluto's orbit is so eccentric that there are times when it is closer to the star than Neptune.
