7 interesting facts about Jupiter
Jupiter was named by roman astrologers. It is huge and has a strong magnetic field and more satellites than any planet in the solar system. Astronomers have known it since ancient times, but the invention of the telescope and the advent of modern astronomy have taught us much about this host giant.
In short, there are many interesting facts that many do not know about this host giant. And here at Universe Today, we’ve freely edited a list of 10 of the most interesting things we think will captivate and surprise you.
Jupiter is Massive:
It is a well-known fact that Jupiter is the largest planet in the solar system. However, this explanation is not really correct. For one thing, Jupiter’s mass is 318 times that of Earth. In fact, Jupiter is 2.5 times as large as all the other planets in our solar system combined. But this is really interesting …
Jupiter is the largest planet in our solar system, 2.5 times the combined mass of all other planets.
As Jupiter gets bigger, it actually gets smaller. The extra mass actually makes the planet denser and begins to pull itself. Astronomers estimate that Jupiter can be four times its current mass and still be more or less the same size.
Jupiter cannot be a star:
Astronomers call Jupiter a failed star, but this isn’t really a good explanation. Yes, Jupiter is as rich in hydrogen and helium as stars, but Jupiter does not have enough mass to undergo a fusion reaction. This is a method in which a star fuses hydrogen atoms under extreme pressure and heat to produce helium, and in the process emits light and heat to generate energy.
This is possible thanks to the huge gravity. In order for Jupiter to ignite the fusion process and become a star, it will need more than 70 times its current mass. If we can crash dozens of Jupiter together, we may have a chance to create a new star. But in the meantime, Jupiter will continue to be a giant host giant with no chance of becoming a star. Excuse me, Jupiter!
Jupiter is the fastest rotating planet in our solar system:
Despite its size and mass, Jupiter is definitely moving fast. In fact, at a rotation speed of 12.6 km / s (~ 7.45 m / s) or 45,300 km / h (28,148 mph), it only takes about 10 hours for a planet to make one revolution when it completes. And because it rotates so fast, the planet flattens a little at the poles and bulges at the equator.
In fact, Jupiter’s equator point is more than 4,600 km from the center of the pole. In other words, the polar radius of the planet is 66,854 ± 10 km (or 10,517 on Earth) and the diameter at the equator is 71,492 ± 4 km (or 11,209 on Earth). This rapid rotation also helps generate a strong magnetic field for Jupiter and contributes to the dangerous radiation around it.
Jupiter’s clouds are only 50 km thick.
Yes, all the beautiful spinning clouds and storms found on Jupiter are only about 50km thick. They are made up of ammonia crystals divided into two different cloud layers. Dark matter is thought to be a compound that is drawn from the depths of Jupiter and changes color when it reacts with sunlight. But under those clouds, there is only hydrogen and helium to the end.
The Great Red Spot has been around for a long time:
Jupiter’s Great Red Spot is one of its most famous features. This persistent anticyclone storm, south of the equator, ranges from 24,000 km in diameter to 12 to 14,000 km in height. Thus, it is large enough to contain two or three planets the size of the Earth’s diameter. And this place has existed for at least 350 years since it was discovered in the 17th century.
The Great Red Spot was first identified in 1665 by the Italian astronomer Giovanni Domenico. In the 20th century, astronomers began to theorize that it was a storm caused by Jupiter’s fast-moving eddy. These theories were confirmed by Voyager 1’s mission, which carefully observed the Great Red Spot as it passed through the planet in March 1979.
However, it seems to have decreased since then. Based on Cassini’s observations, the size of the 17th century is estimated to be 40,000 km, almost double what it is today. Astronomers don’t know if it will disappear completely or when it will disappear, but it is relatively certain that another astronomer will appear somewhere on Earth.
Jupiter has 67 satellites & also Jupiter has a ring:
Of course, when people think of the ring system, Saturn comes to mind. But in reality, both Uranus and Jupiter have their own ring system. That of Jupiter was the third group discovered (following the other two) due to the fact that they are particularly weak. Jupiter’s ring consists of three main segments: a torus on the inside of a particle called a halo, a relatively bright main ring, and a chiffon ring on the outside.
It is widely believed that these rings are derived from material released from satellites by meteorite impacts.
The main ring is thought to be composed primarily of the materials of the Adrastea and Metis satellites, while the Thebes and Amalthea satellites are thought to produce two separate components of dusty gauze ring.
Due to the strong gravity of Jupiter, this material has fallen into orbit around Jupiter (rather than returning to its respective moons). As some material drifts to Jupiter, the ring is also exhausted and replenished regularly, but additional impact adds new material.
At the time of this writing, Jupiter has 67 confirmed and named satellites. However, it is estimated that there are more than 200 satellites in orbit on Earth. Most of them are less than 10 kilometers in diameter and were discovered only after 1975, when the first spacecraft (Pioneer 10) reached Jupiter.
However, there are also four major satellites, collectively referred to as the Galileo satellites (after their discovery by Galileo Galilei). This is in the order of distance from Jupiter, Io, Europe, Ganymede, and Calisto. These satellites are one of the largest in the solar system, with Ganymede being the largest and 5,262 km in diameter.
Jupiter’s magnetic field is 14 times stronger than Earth’s magnetic field:
The compass really works on Jupiter. This is because it has the strongest magnetic field in the solar system. Astronomy believes that the magnetic field is generated by eddy currents, the swirling motion of the conductive material within the liquid metallic hydrogen core.
This magnetic field traps sulfur dioxide particles from the Io volcanic eruption, producing sulfur and oxygen ions. Together with the hydrogen ions formed in Jupiter’s atmosphere, they form a sheet of plasma on Jupiter’s equatorial plane.
Further away, the interaction between the magnetosphere and the solar wind causes an arc shock. This is a dangerous radiation belt that can damage the spacecraft. Jupiter’s four largest moons all rotate in the magnetosphere, protecting them from the solar wind, but also making it difficult to set up an outpost on their surface. Jupiter’s magnetosphere is also responsible for intense radio radiation episodes from the planet’s polar regions.
Jupiter is the third brightest object in the solar system, after Venus and the Moon.
Perhaps you saw Jupiter in the sky, and you had no idea what you were looking at. And here at Universe Today, it’s customary to let readers know when it’s best to see Jupiter in the night sky.
If you see a very bright star high in the sky, you may be looking at Jupiter. Get your binoculars. It’s even better if you know someone who has a telescope. Even at moderate magnification, it can even detect small spots of light that orbit them, which are Galilean satellites. please think about it. You can see exactly what Galileo did when he saw the planet in 1610.
