Neptune’s distance from the Sun is 4.5 billion km; more specifically, it’s 4,503,443,661 km. If you’re still using the Imperial system, that’s the same as 2.8 billion miles.
From an average distance of 2.8 billion miles (4.5 billion kilometers), Neptune is 30 astronomical units away from the Sun. One astronomical unit (abbreviated as AU), is the distance from the Sun to Earth.
When the icy planet is closest to the sun, it lies "only" 2.77 billion miles (4.46 billion km). At its farthest, it passes 2.82 billion miles (4.54 billion km) from the star.
Its vast distance from the Sun means that from its discovery in 1846 until 2011 it had made just one full rotation of its orbit around our solar system’s only star. It takes roughly 165 years for Neptune to complete its orbit of the Sun. Neptune at its closest is 2.7 billion miles from Earth.
It orbits at an average distance of 2.8 billion miles (4.5 billion km), thirty times farther than Earth. Orbit around the Sun: It takes 165 Earth years for Neptune to go around the Sun...
From an average distance of 2.8 billion miles (4.5 billion kilometers), Neptune is 30 astronomical units away from the Sun. One astronomical unit (abbreviated as AU), is the distance from the Sun to Earth.
Neptune's distance from the sun is 2.8 billion miles, or 30 times as far as Earth, and therefore about 2.7 billion miles from Earth. It is famed for its blue color. Neptune is the eighth planet from the sun and the most distant after the demotion of Pluto to dwarf planet status in 2005.
The average distance of Neptune from the Sun is 2,795,084,800 miles or 4,498,252,900 kilometers. Because its orbit is elliptical, its distance from the Sun changes depending on where it is in its orbit. The closest Neptune gets to the Sun is 2,771,087,000 miles or 4,459,630,000 kilometers.
At its average distance of 2.76 billion miles (4.4 billion km), light takes 4.1 hours to reach Neptune from Earth. As the planets orbit the Sun, this time varies between 4.03 hours and 4.17 hours (242 minutes and 250 minutes).
Dark, cold and whipped by supersonic winds, giant Neptune is the eighth and most distant major planet orbiting our Sun. More than 30 times as far from the Sun as Earth, Neptune is not visible to the naked eye.
