Nov 6, 2024 · Orbit and Rotation. One day on Neptune takes about 16 hours (the time it takes for Neptune to rotate or spin once). And Neptune makes a complete orbit around the Sun (a year in Neptunian time) in about 165 Earth years (60,190 Earth days). Sometimes Neptune is even farther from the Sun than dwarf planet Pluto.

Because Neptune is not a solid body, its atmosphere undergoes differential rotation. The wide equatorial zone rotates with a period of about 18 hours, which is slower than the 16.1-hour rotation of the planet's magnetic field.

Neptune’s elliptical orbit is inclined at 1.77 degrees when compared to our own planet. Because of its 0.011 eccentricity, the distance between Neptune and the Sun often varies by around 101 million km between the perihelion and aphelion, which are the nearest and the farthest points of the planet from the Sun along its orbital path ...

Find out information about the planet Neptune, the eighth and farthest planet from the sun in the Solar System. Its rotation, its revolution, distance from the Sun, its great dark spot, its composition, its moons or satellites and its rings.

On October 24, 1996, Hubble captured a time-lapse color movie to show a full 16-hour rotation of the planet Neptune, letting astronomers and scientists track weather patterns on the gas giant. The vivid imagery (and beautiful shades of blue) that the HST captured of …

Mar 2, 2025 · Neptune, third most massive planet in the solar system and the eighth and outermost planet from the Sun. Neptune has 14 moons, only two of which were discovered before Voyager 2’s visit in 1989, and a system of rings, which were unconfirmed before Voyager.

Dec 14, 2024 · Neptune’s rotation period was established when Voyager 2 detected radio bursts associated with the planet’s magnetic field and having a period of 16.11 hours. This value was inferred to be the rotation period at the level of the planet’s …

Feb 22, 2025 · Axial tilt (obliquity) is the angle between a planet’s rotational axis and a perpendicular to its orbital plane. Axial tilt determines the severity of seasonal variations on a planet. Planetary axial tilts result from their formation history, collisions, and gravitational interactions. Earth’s axial tilt (23.44°) is responsible for its ...

A rotating Neptune as seen through the eye of NASA's Hubble Space Telescope. The planet is exhibiting an increase in brightness and in the amount of clouds observed in the planet's southern hemisphere. The changes suggest that Neptune is undergoing seasonal change.
