WebJun 7, 2024 · It takes Neptune nearly 170 Earth years to complete one orbit around the sun at such a vast distance. Since its discovery, Neptune has only completed one full sun rotation. Like all the other planets, Neptune orbits the sun in an ellipse, meaning that the distance between the sun and Neptune changes through the planet's orbit. The average distance between Neptune and the Sun is 4.5 billion km (about 30.1 astronomical units (AU)), and it completes an orbit on average every 164.79 years, subject to a variability of around ±0.1 years. The perihelion distance is 29.81 AU; the aphelion distance is 30.33 AU. On 11 July 2011, Neptune completed its first full barycentric orbit since its disc… can melanin be extracted
