🎶 You’re hot and you’re cold 🎶
On today’s Goddard Glossary, we’re diving into hot Jupiters: a type of exoplanet that is similar in size to Jupiter but orbits extremely close to its star. These gas giants complete their orbits in just days, and their proximity means they’re heated to scorching temperatures.
There are also hot Neptunes, also orbiting close to their star, as well as cold Neptunes and cold Jupiters, which are farther away and absorb less heat.
