... until it was downgraded to a dwarf planet like Makemake. Dwarf planets are basically too small to be labelled as planets, but they still are spherical objects – like planets – and bigger than asteroids. We know very little about our closer dwarf planets, and knew practically nothing about Makemake. ...

... stars we live among. From Earth, we’ve begun to look out at the rest of the Milky Way. We can already make out, dimly, the light from planets orbiting distant stars. We’ve even tasted a few of their atmospheres by dissecting those faint traces of light. The goal of finding a planet outside our solar ...

They called these objects "planets," meaning wanderers, and named them after Roman deities— Jupiter, king of the gods; Mars, the god of ...

... Migration appears to solve the hot Jupiter problem: massive planets can move in from beyond the ice line to close to stars. However, migration suffers from two major problems: Firstly, the timescale for rapid (type I) migration is very short (O(105) yrs) – why do planets not fall into their parent s ...
