Polar View of GJ 436b System

About this image

This artist's diagram shows a polar view of the GJ 436 system. The warm, Neptune-sized exoplanet GJ 436b resides very close to its star – less than 3 million miles – and whips around it in just 2.6 Earth days. A huge, comet-like cloud of hydrogen nicknamed "The Behemoth" is shown bleeding off of the planet and trailing it like the tail of a comet. The planet is just 30 light-years from Earth.
