Neptune is so far from the Sun that high noon on the big blue planet would seem like dim twilight to us. The warm light we see here on our home planet is roughly times as bright as sunlight on Neptune. The ice giant Neptune was the first planet located through mathematical calculations.
The planet is named after the Roman god of the sea, as suggested by Le Verrier. Neptune's environment is not conducive to life as we know it. The temperatures, pressures, and materials that characterize this planet are most likely too extreme and volatile for organisms to adapt to.
With a radius of 15, If Earth were the size of a nickel, Neptune would be about as big as a baseball. From an average distance of 2. One astronomical unit abbreviated as AU , is the distance from the Sun to Earth.
From this distance, it takes sunlight 4 hours to travel from the Sun to Neptune. 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 Earth years 60, Earth days.
Sometimes Neptune is even farther from the Sun than dwarf planet Pluto. Pluto's highly eccentric, oval-shaped orbit brings it inside Neptune's orbit for a year period every Earth years.
This switch, in which Pluto is closer to the Sun than Neptune, happened most recently from to Pluto can never crash into Neptune, though, because for every three laps Neptune takes around the Sun, Pluto makes two.
This repeating pattern prevents close approaches of the two bodies. This means that Neptune experiences seasons just like we do on Earth; however, since its year is so long, each of the four seasons lasts for over 40 years. Neptune has 14 known moons. Neptune's largest moon Triton was discovered on October 10, , by William Lassell, just 17 days after Johann Gottfried Galle discovered the planet.
Since Neptune was named for the Roman god of the sea, its moons are named for various lesser sea gods and nymphs in Greek mythology. Triton is the only large moon in the solar system that circles its planet in a direction opposite to the planet's rotation a retrograde orbit , which suggests that it may once have been an independent object that Neptune captured. Triton is extremely cold, with surface temperatures around minus degrees Fahrenheit minus degrees Celsius.
And yet, despite this deep freeze at Triton, Voyager 2 discovered geysers spewing icy material upward more than 5 miles 8 kilometers. Triton's thin atmosphere, also discovered by Voyager, has been detected from Earth several times since, and is growing warmer, but scientists do not yet know why. Neptune has at least five main rings and four prominent ring arcs that we know of so far. Starting near the planet and moving outward, the main rings are named Galle, Leverrier, Lassell, Arago, and Adams.
The value of the distance of Neptune from Earth is also available as a real time updated value in the Live Position and Data Tracker. This site cannot run without your voluntary donations.
