How old is Jupiter and how old is Jupiter?

4.6 billion years old. Sometime 4.6 billion years ago, a young star was born inside a collapsed cloud of hydrogen molecules. This is the sun. The birth of the sun means the formation of the solar system.

When the first rays of the sun crossed the primordial solar system, a huge gaseous planet appeared in front of the sun. This massive gas planet is Jupiter. Jupiter is the first planet to appear in the solar system.

It appeared in the solar system at the same time as the sun. Therefore, Jupiter is still 4.6 billion years old. It took millions of years for the Sun and Jupiter to form Earth and several other planets.

Hello, I'm glad to answer your questions.

Jupiter. 4.6 billion years old.

Jupiter is the first planet to appear in the solar system. It appeared in the solar system at the same time as the sun. Therefore, Jupiter is still 4.6 billion years old.

I hope I am helpful to you and I wish you a happy life!

Jupiter is a huge planet. Of all the planets in the solar system, Jupiter is the largest. Its diameter is 143,000 kilometers, more than 11 times the diameter of the Earth, and its volume is more than 1,300 times that of the Earth.

This means that if Jupiter were a hollow sphere, it would be able to hold 1,300 Earths in it. Jupiter is the number one giant among the planets of the solar system.

The mass of Jupiter is majestic. Although Jupiter has a mass of only 1,1000 times that of the Sun, it has a mass of 318 times that of the Earth, and Jupiter's mass is even greater than the mass of all the other planets, moons, asteroids, meteorites and comets in the solar system combined, which is only 40 per cent of the mass of Jupiter. In front of the planets, Jupiter looks majestic.

Jupiter appears bright among the stars. Although it travels 5 times as far from the Sun as from the Earth to the Sun, the resulting sunlight is also much weaker, only 1 7 times the brightness of the Sun as seen from the Earth. But Jupiter is huge, has a dense atmosphere, and has a strong ability to reflect the sun's light.

Jupiter is the brightest planet in the sky besides Venus. Jupiter is brighter than Sirius, the brightest star in the starry sky, and brighter than Mars. Westerners placed the throne of Jupiter, the majestic Roman god, on Jupiter.

Jupiter is another "fragile giant". Comparing Jupiter's mass to its sheer size shows no advantage. We know that the ratio of mass to volume is density, and the average density of Jupiter is less than 1 4 of the average density of the Earth.

The average "weight" of Earth's material per square centimeter is 5,52 grams, while a few cubic centimeters of Jupiter's material "weighs" only 1,33 grams, which is only a little heavier than water. Its astonishingly low density and enormous size tell us that Jupiter is made of very light matter, and that Jupiter may contain a considerable amount of water and material lighter than water. It turns out that Jupiter's basic composition is liquid hydrogen, which does not have a solid surface like Earth's land, except that it may have a small molten core.

Jupiter rotates very quickly. It is a huge planet, but it is flexible. Jupiter is more than any other planet in the solar system, the "day" on Jupiter is only 9 hours and 55 minutes, the weak sunlight, the average daily irradiation time is only about 5 hours, human beings have measured the surface temperature of Jupiter to be about minus 150, which is an extremely cold world.

Jupiter orbits at 13 km/s, which is much slower than Earth's orbit of 30 km/s, and one revolution is almost equal to 12 years.

Jupiter is a very obvious ellipsoid, not counting the rings, with an average diameter of about 11 times that of the Earth, a volume of about 1,300 times that of the Earth, and a mass of more than 300 times that of the Earth, and the sum of the mass of the other seven planets plus Pluto is less than 40% of the mass of Jupiter.

Jupiter is the largest and fastest rotating planet among the eight planets in the solar system, the fifth planet from the inside out. It has a mass of one-thousandth the mass of the Sun and a mass of the other seven planets in the Solar System combined. Jupiter, Saturn, Uranus, and Neptune are all gas planets, so they are also called Jupiter-like planets (Jupiter and Saturn are collectively called gas giants).

Jupiter is a gas giant composed mainly of hydrogen, followed by helium, which accounts for 25% of the total mass and 70% of all planets in the solar system, and the core contains other heavier elements. What humans see is usually the tip of the clouds in the atmosphere, with a slightly higher pressure than 1 atmosphere. Jupiter appears as an oblate sphere (a slight but noticeable bulge near the equator) due to its rapid rotation.

The outer atmosphere is clearly divided into multiple zones according to latitude, and the margins where each zone is connected are prone to turbulence and storms. The most notable example is the Great Red Spot, which was first discovered with telescopes in the 17th century. Orbiting the planet is a weak system of planetary rings and a powerful magnetosphere.

Jupiter has at least 79 moons.

Jupiter has a diameter of 142984 kilometers, a volume equivalent to 1,316 Earths, and a mass equivalent to 318 Earths.

Scientists have discovered that Jupiter has 79 moons, making it the second most numerous planets in the solar system.

Pictured here is Jupiter and its two moons, Europa and Europa. The bright yellow moon to the lower left of Jupiter is Europa.

With a diameter of 3,642 kilometers, Europa is the fourth largest planet in the solar system. Io is 166 kilometers larger than the Moon. If you put Europa and the moon together, it's a little bigger. But in front of Jupiter, it is just too small.

Jupiter: 122 times Earth).

Jupiter is a giant planet with a mass of one-thousandth the mass of the Sun, but twice the mass of the other planets in the solar system combined. Jupiter's main component is hydrogen, but helium, which accounts for only one-tenth of the molecular quantity, makes up a quarter of the total mass; It may have a rocky core and heavy elements, but no solid surface that can be clearly defined.

Due to its rapid rotation, Jupiter's appearance appears as an oblate sphere. The atmosphere is divided into different zones of latitude, with turbulence and storms at the junction of each other. The most striking example of this is the Great Red Spot, a huge storm that has not stopped since it was first seen by a telescope in the 17th century.

Macro acre code. Jupiter is also surrounded by faint planetary rings and a powerful magnetosphere, including four Galileo moons, discovered in 1610, and as of September 2022, Jupiter is known to have 80 moons. Ganymede is the largest of these, and its diameter is larger than that of the planet Mercury.

3. Ganymede was discovered by Galileo with a telescope in 1610 and is called the Galilean Moon. Barnard discovered Europto in 1892, and other moons were discovered by photographic methods after 1904. The Voyager spacecraft discovered Europa XIV in 1979, followed by Europa XV and Callisto XVI in 1980.

With the exception of the four Galilean moons, the rest of the moons have a radius of several thousand meters to 20 kilometers of large rocks. With a radius of 2,631 kilometers, Ganymede is the largest of the moons and larger in diameter than Mercury. Europa may have a liquid ocean.

Jupiter's four Galilean moons and the orbits of Europa are almost on Jupiter's equatorial plane.

Jupiter's motion is gradually slowing down. Similarly, the same gravitational force also changes the orbits of the moons, causing them to slowly and gradually move away from Jupiter. Ilymede.

Jupiter (Mu Xing), formerly known as the Star of the Year, is the fifth planet near the Sun and the largest of the eight planets, twice as massive as all other planets (318 times that of Earth). Jupiter's orbit around the Sun is in days, about years. Jupiter (jove) called by the Greeks Zeus (king of the gods, ruler of Mount Olympus and protector of the Roman state), it is cronus (son of Saturn.

Orbit: 778,330,000 km from the Sun ( AU) Planet diameter: 142,984 km (equatorial ) Mass: kg.

Jupiter is the fourth brightest object in the sky (after the Sun, Moon, and Venus; Sometimes Mars is brighter), Jupiter has been known to mankind since prehistoric times. According to Galileo's 1610 observation of Jupiter's four moons: Io, Europa, Ganymede, and Ganymede (now often referred to as Galileo's moons), they were the first discoveries that did not orbit around the Earth, and they were the main basis for agreeing with Copernicus's heliocentric theory of planetary motion.

For many years, it was thought that Europa was discovered by Galileo Galilei in 1609 through his homemade telescope, along with Callis.

1. Ganymede. 2. Ganymede is known as the Galileo moon. In fact, Ganymede was discovered by Gander, an astronomer in the Warring States period of China, who wrote two books, "The Book of Stars and Astronomical Astronomical Horoscopes", but unfortunately both of them were lost.

There is such a record in the twenty-third volume of the "Kaiyuan Zhanjing" compiled by the Tang Dynasty astronomer Qu Tan Siddha: "Gan said: The age of the single cast, the setig is in the mao, the year star is in the son, and the bearded girl, the void, the danger of the morning and the evening in, its shape is very large and bright, if there is a small red star attached to its side, it is called an alliance."

Gander discovered Ganymede as early as 346 BC, almost 2,000 years before Galileo.

Jupiter is the largest planet in the solar system, with an equatorial radius of 71,400 kilometers, which is twice the radius of the Earth's equator, 1,316 times the volume of the Earth, and a mass twice that of the Earth.

He's just smaller than the sun.
