Planet Nine could be surrounded by up to 20 hot moons

It has been six years since astronomers found strong evidence that a mysterious ninth planet might exist at the far reaches of our solar system. Experts say Planet Nine could be surrounded by up to 20 hot moons measuring around 62 miles -wide, which could be the key to confirming the mysterious world's existence. Peculiar: The theoretical Planet Nine that astronomers think may be lurking at the far reaches of our solar system could be surrounded by up to 20 hot moons, a new study suggests There are many things fascinating about this possible Planet X, but chief among them is that its hypothetical orbit would see it take between 10,000 and 20,000 years to make a single pass around the sun. The reason he thinks these could quite literally shed light on Planet Nine is because of a gravitational phenomenon known as tidal heating. Breakthrough: In 2015, Caltech astronomers Mike Brown and Konstantin Batygin announced new research which provided impelling evidence of a giant planet tracing an unusual, elongated orbit in the outer solar system Tidal heating could theoretically raise the temperature of any Planet Nine moon to around minus 280 degrees Fahrenheit.
