Planet Neptune

The planet with a great dark spot that eventually disappeared was Neptune. This large dark spot was first observed in 1989 by the Voyager 2 spacecraft but had disappeared by the time Hubble Space Telescope observed Neptune in 1994. The exact cause of its disappearance is still not fully understood.

The dark spot mentioned likely refers to a storm on Neptune known as the Great Dark Spot. This storm was observed by the Hubble Space Telescope in 1989 but had disappeared by 1995 when the Voyager 2 spacecraft revisited Neptune. The reasons for its disappearance are still not fully understood.

Neptune's impact on Earth is minimal since it is a distant planet in our solar system. Its gravitational pull is far weaker compared to more nearby bodies like the Sun and the Moon, which have a greater influence on Earth's orbit and tides. Neptune's presence mainly affects the outer regions of the solar system.

Neptune has the slowest orbital velocity among the planets because it is the farthest from the Sun among the eight planets in our solar system. The gravitational force decreases with distance from the Sun, resulting in slower orbital speeds at farther distances.

It is not possible to physically touch Neptune with special gloves or any other means as it is a gas giant planet located in our solar system, composed mainly of hydrogen and helium. Neptune does not have a solid surface like Earth, so any attempt to touch it would not be feasible.

I do not understand your question, but I can tell you that Neptune has 13 moons and Pluto has 3.

No. The existence of Neptune was predicted in 1821 by Alexis Boulevard and was later discovered by Urbain Le Verrier in 1846. Newton died in 1727.

No, the moons of Neptune are not close to each other. They are spread out in various orbits around the planet, with significant distances between them. Some of the major moons of Neptune include Triton, Proteus, and Nereid.

Urbain Le Verrier was born in France.

No, as of now, there have been no manned or unmanned space flights to Neptune. The distance, challenges of sending a mission to such a distant planet, and technological limitations make it currently not feasible to send a spacecraft to Neptune.

There are no man-made satellites or robots of Neptune. The space probe "Voyager 2" flew past Neptune, in 1989.

No, Voyager 2 is not the only spacecraft to study Neptune. The Hubble Space Telescope and the Keck Observatory have also observed Neptune. Additionally, the European Space Agency's Huygens probe studied Neptune's moon Triton.

Neptune's atmosphere, while similar to Jupiter's and Saturn's in that it is composed primarily of hydrogen and helium, along with traces of hydrocarbons and possibly nitrogen, it contains a higher proportion of "ices" such as water, ammonia and methane. Astronomers sometimes categorize Uranus and Neptune as "ice giants" in order to emphasize these distinctions.

13 of them, considerably fewer than many other large gas planets.

A 70 pound person on Earth would weigh approximately 97 pounds on Neptune. Neptune's gravity is about 1.14 times stronger than Earth's gravity, resulting in the increase in weight.

There is no oxygen on Neptune, so, no.

In theory, you may be able to in a space suit, but still, physically, no, you can't breathe on Neptune.

Neptune is too cold to support life and too cold for electronic equipment to operate properly (such as space suits).

Neptune does not have a significant internal heat source like other planets such as Earth or Jupiter. Its heat mainly comes from the Sun, with temperatures on the surface averaging around -200 degrees Celsius. The planet's deep atmosphere absorbs sunlight and generates strong winds and storms, but it is not considered a hot planet.

About a factor of 21.5. One of Neptune's moons, Triton, is about 20% larger than Pluto.

Neptune's smaller size and farther distance from the Sun may have limited its ability to capture as many moons as Jupiter and Saturn. Additionally, its irregular orbit and gravitational interactions with other celestial bodies may have hindered moon formation around Neptune.

They don't.

Neptune is −218°C (55.1K / -360.4°F).

Uranus is -224 °C (49K / -371.2°F ).

Neptune, the 8th planet, is the furthest planet from the sun, however it has an exposed core composed of extremely hot molten ammonia. Which provides a little heat to the planet, but still not enough to prevent it being freezing.

Because of Neptune's very hot core, Uranus, the 7th planet, is the coldest.

Their cold temperatures are because they are too far from the sun for its heat to warm them.

Neptune, the Roman god of the sea, is often depicted carrying a trident, which symbolizes his control over the waters. He is also sometimes shown holding a dolphin, as dolphins were believed to be sacred to him. Additionally, he was associated with horses and chariots, so sometimes he is depicted with a chariot or horses.
