“Absolutely Electrifying” –‘We Will Image Planet Nine Within the Next Decade’

Planet Nine

 

“At five Earth masses, Planet Nine is likely to be very reminiscent of a typical extrasolar super-Earth,” says Konstantin Batygin, an assistant professor of planetary science and Van Nuys Page Scholar at Caltech. Super-Earths are planets with a mass greater than Earth’s, but substantially less than that of a gas giant. “It is the solar system’s missing link of planet formation. Over the last decade, surveys of extrasolar planets have revealed that similar-sized planets are very common around other sun-like stars. Planet Nine is going to be the closest thing we will find to a window into the properties of a typical planet of our galaxy.”
