Newfound ‘hot Jupiter’ celebrates New Year’s every 5 days

Still suffering from a New Year hangover? How would you feel doing it all again in less than a week? If you lived on a newly-discovered exoplanet, you’d have to do just that: Astronomers have spotted a planet three times the size of Jupiter orbiting a rapidly-spinning dwarf star around 530 light-years from Earth that celebrates a trip around its sun every five days!

This newfound exoplanet, designated TOI-778 b, is an example of a so-called “hot Jupiter,” a world similar to our solar system’s largest planet, the gas giant Jupiter, but located in extreme proximity to its star. This proximity gives rise to extreme conditions such as surface temperatures hot enough to vaporize iron and orbits of under ten Earth days.
