Neptune

It is the fourth-largest planet in the Solar System by diameter, the third-most-massive planet, and the densest giant planet. It is 17 times the mass of Earth, and slightly more massive than its near-twin Uranus. Neptune is denser and physically smaller than Uranus because its greater mass causes more gravitational compression of its atmosphere. With a radius of 15,299.4 miles (24,622 kilometers), Neptune is about four times wider than Earth. If Earth were the size of a nickel, Neptune would be about as big as a baseball. From an average distance of 2.8 billion miles (4.5 billion kilometers), Neptune is 30 astronomical units away from the Sun.

The Great Dark Spot (centre left) is 13,000 km (8,100 miles)—about the diameter of Earth—in its longer dimension. Accompanying it are bright, wispy clouds thought to comprise methane ice crystals. At higher southern latitudes lies a smaller, eye-shaped dark spot with a light core (bottom left). Just above that spot is a bright cloud dubbed Scooter. Planet Neptune Overview Dark, cold and whipped by supersonic winds, giant Neptune is the eighth and most distant major planet orbiting our Sun. More than 30 times as far from the Sun as Earth, Neptune is not visible to the naked eye.

A trip around Neptune's equator would cover 96,129 miles (154,705 km). Such a trip.

Size: Neptune is slightly smaller than Uranus and has a diameter of 31,000 miles (50,000 kilometers), so about 4 Earths would fit across its face. Distance from the Sun: Neptune is the eighth. Neptune's equatorial diameter measured at the one-bar pressure level (the pressure of Earth's atmosphere at sea level) is 49,528 km (30,775 miles), which is only about 3 percent shy of the diameter of Uranus. Diameter: 49,528 kilometers (30,775 miles), Neptune is 3.9 times wider than Earth Volume: 63 trillion km3 (15 trillion mi3), Earth could fit inside Neptune 63 times Gravity: 11 m/s², or 1.1 times that of Earth's Solar day: 16 Earth hours Solar year: 60,190 Earth days Atmosphere: 80% hydrogen, 19% helium, 1% other gases How we study Neptune Neptune is the fourth largest planet in our Solar System and it is the smallest of the giant gas planets. Neptune has a diameter of 34,503 miles (55,528) kilometers. Its volume is 57.7 times the volume of Earth which means that 57 Earths could fit inside of Neptune with a little room left over.

It has an equatorial diameter of 30,775 mi (49,528 km). Neptune consists largely of hydrogen and helium. It has no solid surface; its interior is believed to consist of a fluid mixture of rock, ices, and gas. Its atmosphere contains substantial amounts of methane gas, whose absorption of red light causes Neptune's deep blue-green colour. All About Neptune. Neptune is dark, cold, and very windy. It's the last of the planets in our solar system. It's more than 30 times as far from the sun as Earth is. Neptune is very similar to Uranus. It's made of a thick fog of water, ammonia, and methane over an Earth-sized solid center. Its atmosphere is made of hydrogen, helium, and methane. Orbiting the sun at a distance of 2.8 billion miles (4.5 billion kilometers), Neptune is the fourth-largest planet by diameter and third-largest by mass, having a diameter of 30,598 miles (49,244 kilometers). Orbiting at a distance of roughly 2.8 billion miles from the sun, Neptune is the furthest planet yet discovered in our solar system (that is, after Pluto's reclassification as a dwarf planet in.

Bibliography Neptune is the eighth and farthest planet from the sun but it is not the coldest. Our solar system 's blue gas giant is far larger than Earth, at more than 17 times Earth's mass and. The diameter of Neptune is approximately 49,500 km. This makes Neptune the 4th largest planet in the Solar System, after Jupiter, Saturn and Uranus. I say approximately because the diameter of.
