Ten interesting facts about Jupiter

Here is a list of some interesting facts about the planet Jupiter. A planet that catches the attention of all, by its size, storms and its surprising moons.

The mass of Jupiter is 318 times as massive as the Earth. In fact, Jupiter is 2.5 times more massive than all of the other planets in the Solar System combined.

Its gravity is so strong that a rocket would have to go an unthinkable 135,000 mph to leave.

The Great Red Spot on Jupiter is one of its most familiar features. This persistent anticyclonic storm, which is located south of its equator, measures between 24,000 km in diameter and 12–14,000 km in height. As such, it is large enough to contain two or three planets the size of Earth’s diameter. And the spot has been around for at least 350 years, since it was spotted as far back as the 17th century.

Jupiter’s rings were discovered in 1979 by the passing Voyager 1 spacecraft, but their origin was a mystery. Data from the Galileo spacecraft that orbited Jupiter from 1995 to 2003 later confirmed that these rings were created by meteoroid impacts on small nearby moons.

Extending up to seven million kilometers in the Sun’s direction and almost to the orbit of Saturn in the opposite direction, Jupiter’s magnetosphere is the largest and most powerful of any planetary magnetosphere in the Solar System, and by volume the largest known continuous structure in the Solar System after the heliosphere.

Jupiter has a total of 69 natural satellites. The four largest are: Io, Europa, Ganymede and Callisto. However, it is estimated that the planet has over 200 natural satellites orbiting it. Almost all of them are less than 10 kilometers in diameter, and were only discovered after 1975, when the first spacecraft (Pioneer 10) arrived at Jupiter.

Jupiter Has Been Visited 8 Times By Spacecraft. Jupiter was first visited by NASA’s Pioneer 10 spacecraft in December 1973, and then Pioneer 11 in December 1974. Then came the Voyager 1 and 2 flybys, both of which happened in 1979. This was followed by a long break until Ulysses arrived in February 1992, followed by the Galileo space probe in 1995. Then Cassini made a flyby in 2000, on its way to Saturn. And finally, NASA’s New Horizons spacecraft made its flyby in 2007. NASA’s Juno spacecraft is currently orbiting Jupiter.

Jupiter is the third brightest object in the Solar System, after Venus and the Moon.

Jupiter Is The Fastest Spinning Planet In The Solar System. For all its size and mass, Jupiter sure moves quickly. In fact, with an rotational velocity of 12.6 km/s (~7.45 m/s) or 45,300 km/h (28,148 mph), the planet only takes about 10 hours to complete a full rotation on its axis. And because it’s spinning so rapidly, the planet has flattened out at the poles a little and is bulging at its equator.

Jupiter Cannot Become A Star. Astronomers call Jupiter a failed star, but that’s not really an appropriate description. While it is true that, like a star, Jupiter is rich in hydrogen and helium, Jupiter does not have nearly enough mass to trigger a fusion reaction in its core. This is how stars generate energy, by fusing hydrogen atoms together under extreme heat and pressure to create helium, releasing light and heat in the process.

This is made possible by their enormous gravity. For Jupiter to ignite a nuclear fusion process and become a star, it would need more than 70 times its current mass. If you could crash dozens of Jupiters together, you might have a chance to make a new star. But in the meantime, Jupiter shall remain a large gas giant with no hopes of becoming a star. Sorry, Jupiter!

You’ve just crossed over into the Twilight Zone. This image captures the swirling cloud formations in Jupiter’s terminator – the region where day meets night.

This image is one in a series of images taken in an experiment to capture the best results for illuminated parts of Jupiter’s polar region. For JunoCam to collect enough light to reveal features in Jupiter’s dark twilight zone, the much brighter illuminated day-side of the planet becomes overexposed with the higher exposure.

I mean like - what was this even? Yeah sure joanne that’s all because of the blood pact

For whither thou goest, I will go, And where thou lodgest, I will lodge. Thy people shall be my people, and thy God my God. Where thou diest, will I die, and there will I be buried. The Angel do so to me, and more also, If aught but death part thee and me.
