If you want to get to neptune, settle in for a long ride because it's really far away The distance between neptune and the sun is about 2.8 billion miles Earth is a measly 93 million miles from the sun, so on the earth's closest approach to neptune, it's about 2.7 billion miles away Traveling to neptune in your average passenger jet would take you around 600 years How far away is neptune from earth The distance of neptune from earth is currently 4,436,071,161 kilometers, equivalent to 29.653304 astronomical units
Light takes 4 hours, 6 minutes and 37.1406 seconds to travel from neptune and arrive to us. Neptune is the farthest planet in the solar system As such, it is one of the hardest planets to study and there is still much that we don't know about it Neptune wasn't discovered until 1846. Neptune’s axis of rotation is tilted 28 degrees with respect to the plane of its orbit around the sun, which is similar to the axial tilts of mars and earth This means that neptune experiences seasons just like we do on earth
Moons neptune has 16 known moons. It gets even more complicated, because both earth and neptune follow the sun on elliptical orbits They both have a closest point to the sun, called perihelion, and a distant point, called aphelion. How long it would take to get to neptune from earth would depend on the path chosen and on where neptune and earth were in their orbits when the mission was launched For example, the voyager 2 spacecraft was launched on aug 20, 1977 and it reached neptune on aug 24, 1989 So, voyager 2 took about twelve years to reach neptune.
