The strongest winds in the Solar System have been recorded on Neptune, at speeds of up to 2,000 kilometres per hour.

Neptune has dark spots similar to the Great Red Spot on Jupiter. These are areas of high atmospheric pressure which force clouds of methane gas high up into the atmosphere, appearing like cirrus (thin, whispy) clouds on Earth. However, these spots disappear and reappear on different parts of the planet, unlike Jupiter's spot.

Neptune sometimes orbits the Sun further away than Pluto making it the most distant planet in the Solar System. It returned to its usual position as the second furthest planet away from the Sun in December 1999.

Triton orbits Neptune in the opposite direction to the planet's rotation. It is the only large moon in the Solar System to do this.

Neptune has four faint rings. Some parts of these rings are brighter in areas than others and appear like arcs orbiting the planet. Maybe they are still forming.
