Latest figures put Neptune at roughly 4.32 billion kilometres from Earth, about 28.91 astronomical units, with light from the planet taking just over four hours to reach us. The data shows Neptune moving slightly farther away, gaining close to 3.7 million kilometres over the past week, while its orbital speed holds steady at about 5.47 km/s. The update was published alongside NASA/JPL imagery of the planet.

Why now: Routine tracking of Neptune's distance attracts space enthusiasts interested in current planetary positions.
