Neptune and Uranus are both ice giants, what is the essential difference between the two?

The biggest difference between "Neptune" and "Uranus", both ice giants, is that they have different orbital radii and different inclination angles of their rotation axis.

When we understand "Neptune" and "Uranus", we will remember that they are also a blue star, indeed, "Neptune" and "Uranus" are the same structure, they are made of hydrogen and nitrogen and other ice-like objects, so they will become ice-like existence! In fact, these two unique ice giants are not exactly similar, the most unique difference is that they are not the same! The planets of the solar system all have their own sizes.

1. The difference between "Neptune" and "Uranus", the most essential difference is that the orbital radius is completely different When it comes to celestial planets, many people are very confused about "Neptune" and "Uranus", after all, these two celestial bodies look really similar, they are both blue stars, but the reality is very different.

In the universe, in fact, Uranus has a lot more physique than Neptune, after all, Neptune's star density is relatively high; In addition, the most essential difference between the two is that their orbital radius is completely different, although they are both planets around the solar system, but different planets have their own orbits and orbit sizes!

According to the current information, in fact, the orbit of Uranus is about 19 astronomical units, while Neptune is 30 units, which means that the former only needs 84 years to orbit the sun, while Neptune needs to pay twice as long to complete the act of orbiting the sun! That's the biggest difference between them.

Second, the rotation mode of the two is also different, what is surprising is that Uranus almost rolls and rotates for rotation, there are always people who mistakenly think that celestial bodies rotate like the earth, but in fact it is not, the way and time of rotation of different celestial bodies are also different.

The rotation of "Neptune" and "Uranus", which both belong to the ice giants, is also significantly different due to the different inclination angles of the rotation axis; According to the data, Neptune's axis of rotation is about 28°, which is very similar to that of the Earth, and the appearance of day and night is similar, but Uranus is a completely different existence.

Anyone who knows the science will remember that Uranus is the only star that rolls and rotates, after all, its axis of rotation is inclinated at a whopping 98°! This means that in the mode in which it rotates in constant rolling; There will be night or day in the northern and southern hemispheres for a long time, and because of such extreme existence, many people believe that Uranus is difficult to exist.

Different inclination angles of the axis of rotation and different orbits of rotation all cause the difference between "Neptune" and "Uranus".

The essential difference between the two is that the substances in their atmospheres are not the same, and the composition of the structure is also different.

It is a very large planet, and this planet can be said to be the 8th planet in the sun. And it is also the fourth largest celestial body. It belongs to the smallest Uranus and has a very large mass.

Neptune, the eighth planet orbiting the Sun and the fourth largest body in the solar system, is a blue planet.

This planet is the farthest planet from the Sun, so it must be seen with an astronomical telescope, and it is generally blue to the naked eye and the temperature is particularly low, and the temperature of the core can reach 7000.

In fact, this is also a very mysterious planet, and there are many substances on this planet, which attract human beings to explore.

NeptuneUranus is a gas planet.

According to scientific explorations, Neptune is a gaseous planet, and in addition to it, there are eight planets.

, the four farthest planets from Earth are all gaseous planets, and they are also the four largest in mass. Jupiter.

Saturn, Uranus, and Neptune masses dominate the solar system.

99% except the Sun, of which Uranus, the least massive, is 14 times more massive than Earth, and Jupiter, the most massive, is 318 times the mass of Earth's ascending sphere.

Scientists have been searching and studying the solar system since a long time, and so far they have found many planets outside the solar system. Exoplanets are quite abundant, at least a few thousand have been discovered so far, and this is a relatively good thing for the study of these planets.

In the astronomical world, the formation of gas planets may be similar to terrestrial planets, with a rather slow adsorption process. Although it is said to be a gas planet, it does not mean that it is composed entirely of gas coincidence. This gaseous planet started out as a slow rotation process, eventually acquiring some rocky material.

Then the adsorption of the gas begins to form a gas layer. The result was the formation of a gas planet.

Neptune is one of the eight planets in the solar system and the farthest known planet from the Sun.

Neptune's orbital semi-major axis is astronomical units, its orbital period is years, its mass is Earth's mass (3rd, slightly larger than its nearest neighbor Uranus), and its radius is Earth's radius (4th).

Neptune's apparent magnitude is about equal at the highest level, and it requires the help of an astronomical telescope to observe. Neptune is blue to the naked eye, and Westerners named it after Neptune, the god of the sea in Roman mythology. When Li Shanlan and others translated "Talking Heaven" in 1859, their Chinese translation was Neptune.

Astral motion. The average distance between Neptune and the Sun is 4.5 billion kilometers, about one astronomical unit (AU). Neptune's orbital period (years) is approximately equivalent to Earth-years, and the orbital inclination is about.

Neptune returned to the point where it was discovered on July 12, 2011, when it orbited the Sun. Since the Earth is in a different part of its celestial cycle, Neptune as seen from the Earth will not be in the same position in the sky as it was discovered.

Observed from Earth, Neptune's opposition cycle is 367 days, and these cycles bring it close to the coordinates of April and July 2010 and October and November 2011 when it was discovered in 1846. On August 20, 2010, Neptune went to opposition again on the same day that it was discovered in 1846.
