Jupiter-like exoplanet orbits its star in only 18 hours
Posted by Genevieve Klien in category: space
Astronomers have observed an exoplanet orbiting a star in just over 18 hours – the shortest orbital period ever seen for a planet of its type.
This means that a single year for this hot Jupiter-like planet – a gas giant similar in size and composition to Jupiter in our own Solar System – passes in less than a day of Earth time.
Scientists believe the discovery may help solve the mystery of whether such planets are in the process of spiralling towards their suns to their destruction.
