when we think about stars. Supermassive balls of white fusion gas are probably what come to mind, but they aren't also big. In fact, in the Milky Way galaxy red Dwarf E B L M j 0555-57 A. B is barely bigger than Saturn, and it's actually smaller than Jupiter. So you might be asking yourself, Why didn't Jupiter ever turned into a star? Jupiter, after all, is made of the same stuff that stars air made of hydrogen and helium. But the biggest factor is its density. Sure, Jupiter may have the mass of 2.5 times the rest of our solar systems planets combined, but its density is only around 1.33 g per cubic centimeter. And yeah, the sun's mass may only be 1.41 g per cubic centimeter. While Jupiter is big on a planetary scale, it's only 0.1 times the mass of our Sun Stars form when the core of a future star is pressed so hard under the gravity of its own mass. That thermonuclear fusion occurs, and Jupiter, while Big, just doesn't have enough mass. So rather than being a failed star. Like some may say, Jupiter is more likely the leftover gasses from the birth of our own solar systems. Son, right?
FM radio signal found coming from Jupiter moon
