Exoplanet Orbits its Star Every 18 Hours. The Quickest Hot-Jupiter Ever Found

In the past decade, thousands of planets have been discovered beyond our Solar System. These planets have provided astronomers with the opportunity to study planetary systems that have defied our preconcieved notions. This includes particularly massive gas giants that are many times the size of Jupiter (aka. “super-Jupiters”). And then there are those that orbit particularly close to their suns, otherwise known as “hot-Jupiters”.

Conventional wisdom indicates that gas giants should exist far from their suns and have long orbital periods that can last for a decade or longer. However, in a recent study, an international team of astronomers announced the detection of a “hot-Jupiter” with the shortest orbital period to date. Located 1,060 light-years away from Earth, this planet (NGTS-10b) takes just 18 hours to complete a full orbit of its sun.

A Very Rare Planet Discovered. Less Massive than Neptune, Hotter than Mercury. Very Few Should Exist

Astronomers have discovered a very rare, very unusual planet in a distant solar system. The planet, called NGTS-4b, is three times the size of Earth, and about 20% smaller than Neptune. It’s hotter than our very own Mercury. At about 1,000 degrees Celsius, it would be the hottest planet if it were in our Solar System.

But what really separates this planet is its location. It’s located in what’s called the Neptunian Desert.
