Neptune-sized planets exhibit a wide range of compositions and densities, depending on factors related to their formation and evolution history, such as the distance from their host stars and atmospheric escape processes. They can vary from relatively low-density planets with thick hydrogen–helium atmospheres1,2 to higher-density planets with a substantial amount of water or a rocky interior with a thinner atmosphere, such as HD 95338 b (ref. 3), TOI-849 b (ref. 4) and TOI-2196 b (ref. 5). The discovery of exoplanets in the hot-Neptune desert6, 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 Earth radii and orbits a dwarf star every 1.24 days. This planet has a mass of 73
Scientists have found hundreds of new exoplanets in data from the Kepler mission. These include 301 new confirmed exoplanets and 366 new planetary candidates.
Scientists have added a whopping 301 newly confirmed exoplanets to the total exoplanet tally. None of the newly confirmed planets are believed to be Earth-like or in the habitable zone of their parent stars.
A jaw-dropping 301 newly confirmed exoplanets have recently been added to the total of worlds outside of our Solar System. These planets are just the latest to be added to the staggering number of 4,569 that have already been confirmed. As for why such a large number of planets were found in a relatively short.
