How long away is Neptune from Earth?
Neptune is 2.7 billion miles (4.3 billion km) away when it is closest to Earth and 2.8 billion miles (4.5 billion km) when it is the furthest from Earth.
What is Neptune’s distance from the Sun and Earth?
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. From this distance, it takes sunlight 4 hours to travel from the Sun to Neptune.

Does Neptune rain diamonds NASA?
Deep within Neptune and Uranus, it rains diamonds—or so astronomers and physicists have suspected for nearly 40 years. The outer planets of our Solar System are hard to study, however. Only a single space mission, Voyager 2, has flown by to reveal some of their secrets, so diamond rain has remained only a hypothesis.

Does Neptune still exist?
It’s the last of the planets in our solar system. It’s more than 30 times as far from the Sun as Earth is. Neptune is very similar to Uranus. It’s made of a thick soup of water, ammonia, and methane over an Earth-sized solid center.
