The relative "hot spot" is due to Neptune's axial tilt, which has exposed the south pole to the Sun for the last quarter of Neptune's year, or roughly 40 Earth years. As Neptune slowly moves towards the opposite side of the Sun, the south pole will be darkened and the north pole illuminated, causing the methane release to shift to the north pole.
In the 1990s, it was determined that Uranus and Neptune were a distinct class of giant planet, separate from the other giant planets, Jupiter and Saturn, which are gas giants predominantly composed of hydrogen and helium. [1] Neptune and Uranus are now referred to as ice giants. Lacking well-defined solid surfaces, they are primarily composed ...
Neptune has 16 known moons; the largest, Triton, accounts for more than 99.5 percent of all the mass orbiting the planet. Triton is large enough to have achieved hydrostatic equilibrium, but, uniquely for a large moon, has a retrograde orbit, suggesting it was a dwarf planet that was captured.
Neptune has long been known to have white clouds circling it, but images of the furthest planet in the solar system have shown this changing over time - the most recent image, taken by the Hubble ...
Neptune has extremely dynamic weather systems, including the highest wind speeds in the Solar System, thought to be powered by the flow of internal heat. Typical winds in the banded equatorial region can possess speeds of around 350 m/s (comparable to the speed of sound at room temperature on Earth [ 31 ] viz. 343.6 m/s) while storm systems can ...

Four years ago, astronomers noticed the abundant clouds on Neptune had largely disappeared. Telescope data may have helped researchers figure out why. Neptune’s clouds have disappeared, and ...
Triton orbits Neptune in a retrograde orbit—revolving in the opposite direction to the parent planet's rotation—the only large moon in the Solar System to do so. [3] [13] Triton is thought to have once been a dwarf planet from the Kuiper belt, captured into Neptune's orbit by the latter's gravity. [14]
