![]() Why is Jupiter sometimes called a "failed star"? When we look out at the incredible range of exoplanets being discovered around other stars, more than 5000 at the last count, we do see evidence for larger planets, some of which are "puffed up" because they're really close to their parent stars and getting a lot of energy from them to heat their atmospheres to thousands of degrees. Jupiter and Saturn are the big Gas Giants, Uranus and Neptune are more "intermediate-sized" Ice Giants, whereas the rocky terrestrial planets are much smaller. Is there a planet bigger than Jupiter?Īlmost certainly, but not here in our solar system. The Great Red Spot has been around since at least the Victorian era, almost two centuries ago, but has been steadily shrinking in east-west extend for much of that time. ![]() The calm air in the interior gets cooked by the ultraviolet light from the sun, creating chemicals and hazes that are very good absorbers of blue light, leaving only red light to be reflected back towards an observer. This vortex is big enough to swallow the Earth twice over, and the winds that whip around its edges do a good job of keeping the calm air inside the vortex separated from turbulent, stormy air outside. Jupiter's famous Great Red Spot is a swirling vortex - technically an anticyclone because it rotates anticlockwise in Jupiter's southern hemisphere. So think of Jupiter as a bottomless ocean of strange, exotic materials. In fact, the hydrogen that is Jupiter's dominant gas gets compressed to such extremes that it changes to an exotic metallic hydrogen form. Pressures at the colorful cloud tops are not dissimilar to those in Earth's atmosphere, but they build up as you go deeper, rather like a submarine experiencing crushing densities as it sinks deeper and deeper into our oceans. Yes, but don't be fooled into thinking that Jupiter is like a big cloud of gas that you could fly through, it's more like a fluid planet that gets denser and hotter the deeper you go. Leigh Fletcher is a professor of planetary science at the University of Leicester in the U.K. We asked Leigh Fletcher, a professor of planetary science a few commonly asked questions about Jupiter. That's 5.203 times farther than Earth's average distance from the sun.Īt perihelion, when Jupiter is closest to the sun, the planet is 460,276,100 miles (740,742,600 km) away.Īt aphelion or the farthest distance that Jupiter reaches from the sun, it is 507,089,500 miles (816,081,400 km) away. On average, Jupiter orbits at about 483,682,810 miles (778,412,020 kilometers) from the sun. Related: How big is Jupiter? How far is Jupiter from the sun? If the planet had been about 80 times more massive during its development, it would have actually become a star in its own right, according to NASA. Jupiter was probably the first planet to form in the solar system, made up of gasses left over from the formation of the sun. If Jupiter were the size of a basketball, Earth would be the size of a grape. Jupiter's immense volume could hold more than 1,300 Earths. Some vintage stereo receiver looks can be reinvented with new colored led lamps! Look at this Realistic Receiver above, the cool LED lamps add an entire new element to this receiver.Jupiter is more than twice as massive as all the other planets combined, according to NASA. Some kits will be for the casual or novice person, other kits will be more in depth and will require more skill to install. Many colors of led lamps, along with many kit varieties are available. There are many options available for you. This is just an example of the difference new LED lamps can make in your vintage stereo receiver. As seen below a Sansui 9090db without LED on the left and a Sansui 9090db with cool white led lamps on the right. Many people are converting these over the a cool white or cool blue to enhance the look of your receiver. These bulbs are available in many colors including a warm white that mimics the original incandescent bulb. Whether your original lamps are starting to burn out or you just want to upgrade your stereo to a brighter look.
