Hot neptune

The discovery of exoplanets in the hot-Neptune desert, a region close to the host stars with a deficit of Neptune-sized planets, provides insights into the formation and evolution of planetary systems, including the existence of this region itself. Here we show observations of the transiting planet TOI-1853 b, which has a radius of 3.46 +- 0.08 ....

Neptune desert, Nature Astronomy (2020). DOI: 10.1038/s41550-020-1142-z Provided by University of Warwick Citation: The first ultra-hot Neptune, LTT 9779b, is one of nature's improbable planets (2020,The interior of Venus is made of a metallic iron core that's roughly 2,400 miles (6,000 km) wide. Venus' molten rocky mantle is roughly 1,200 miles (3,000 km) thick. Venus' crust is mostly basalt, and is estimated to be 6 to 12 miles (10 to 20 km) thick, on average. Venus is the hottest planet in the solar system.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.Of all Neptune's moons though, Triton is the most intriguing. With a whopping diameter of 1,682 miles (2,700km) not only is Triton Neptune's largest moon, but it's also the 7 th largest moon and the 16 th largest known object within our solar system! Discovered by British astronomer William Lassell on October 10, 1846, Triton is so great ...
