Sound waves have been used in the lab to mimic the role that gravity plays in driving convection in huge rotating bodies such as stars and planets. Convection within rotating planets and stars plays an important role in the internal dynamics of these huge objects. Here on Earth, for example, convection in the outer core is believed to create our planet's magnetic field and convection in the atmosphere drives weather patterns.

Our solar system is home to millions of renegade space rocks, and this week three particularly large ones will blaze past Earth. On Monday (Feb. 27), an asteroid named 2012 DK31 will sail past our planet at a distance of about 3 million miles (4.8 million km). Although the space rock poses no imminent threat to Earth, NASA classifies it as a potentially hazardous asteroid (PHA) – meaning the rock is large enough and orbits close enough to Earth that it could cause serious damage if its trajectory changed and a collision occurred.

What if Planet Nine had satellites? Can it help us find Planet Nine more easily? The new paper speculates that any moons orbiting Planet Nine could provide indirect clues to Planet Nine’s location, while revealing fundamental properties of the enigmatic object. Chen Wenhao of the Education University of Hong Kong said that the research shows the possibility that Planet Nine captures a large trans-Neptunian object (TNO) to form a satellite system. We use a benchmark analysis model, and the tidal effect of Planet Nine can significantly heat the satellite.
