Planet Neptune and its largest Moon Triton

Neptune is the outer most planet in our solar system; it orbits the sun with a radius of 2,798,000,000 miles. Neptune is the 4th largest planet by diameter, 3rd largest planet by mass and densest of all the gas giants. Neptune has a great dark spot similar to that of Jupiter. Both spots are Anticyclonic storms, meaning the winds around the storm flow opposite to the direction dictated by the Coriolis effect. However, unlike Jupiter’s spots, Neptune’s dark spots appear to only last a few years (as opposed to a few hundred) and have relatively calm and cloudless centers. Observations have shown that Neptune spends about the same amount of time with and without its largest dark spot. The storms activity seems to cyclical.

Neptune has 14 moons, Triton is the largest and composes more than 99.5% of all the mass that orbits the planet. Triton is roughly the same size as our moon: (Neptune’s Triton vs Earth’s moon)

Triton has a retrograde orbit around Neptune, meaning that it orbits in the opposite of the planet’s rotation.

These images were taken by the Voyager 2 space probe and the Hubble space telescope, with the exception of the last image being an artists impression of Neptune seen from its moon Triton.
