Our Neptune is about four times as wide as the Earth. NASA calls it an ice giant that is dark, cold, and whipped by supersonic winds sitting about 2.8 billion miles away from the Sun. The planet is a Neptune-sized body that whips around its star once every 19 hours. Never before has a Neptune-sized exoplanet been found with an orbital period of less than a day. Usually, exoplanets this close to their star are either gas giants, known as ultra-hot Jupiters , or smaller, rocky planets like Earth, Mercury , Mars and Venus ...In essence, a hot Neptune is a planet that has a mass and radius of the order of that of our own Neptune, but orbits the host star at distance that is less (often much less) than the Earth-Sun distance. (Our Neptune has a mass and radius of 17.1 and 3.9 times the corresponding quantities for Earth, respectively.)

The relative "hot spot" is due to Neptune's axial tilt, which has exposed the south pole to the Sun for the last quarter of Neptune's year, or roughly 40 Earth years. As Neptune slowly moves towards the opposite side of the Sun, the south pole will be darkened and the north pole illuminated, causing the methane release to shift to the north pole.14 Dec 2018 ... This artist's illustration shows a giant cloud of hydrogen streaming off a warm, Neptune-size planet just 97 light-years from Earth. NASA, ESA ...Such lack of planets of intermediate size (the "hot Neptune desert") has been interpreted as the inability of low-mass planets to retain any hydrogen/helium (H/He) envelope in the face of strong stellar irradiation. Here, we report the discovery of an ultra-short-period planet with a radius of 4.6 Re and a mass of 29 Me, firmly in the hot ...Hot Neptune LTT 9779b was discovered just last year, becoming one of the first Neptune-sized planets discovered by NASA's all-sky TESS planet-hunting mission.
