Neptune's festival (Neptunalia) took place in the heat of the summer (July 23), when water was scarcest; thus, its purpose was probably the propitiation of the freshwater deity.Neptune had a temple in the Circus Flaminius at Rome; one of its features was a sculptured group of marine deities headed by Poseidon and Thetis.In art Neptune appears as the Greek Poseidon, whose attributes are the ...1 Introduction. Trans-Neptunian objects (TNOs) are small Solar System bodies that orbit the Sun with a semi-major axis larger than that of Neptune (Jewitt et al. 2008).Due to the low spatial density of material in this orbital region and the significant distance from the Sun, their global physical-chemical composition has been largely unaffected since their formation."This ultra-hot Neptune is a 'medium-sized' exoplanet that orbits very close to its star (it takes just 19 hours to complete an orbit), but its low density indicates that it still has an ...

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. Crossfield and his co-authors used a technique called “phase curve” analysis to parse the exoplanet’s atmospheric makeup.

Here we report that in the ultraviolet the Neptune-mass exoplanet GJ 436b (also known as Gliese 436b) has transit depths of 56.3 ± 3.5% (1 σ ), far beyond the 0.69% optical transit depth. The ...To date, more than 750 planets have been discovered orbiting stars other than the Sun. Two sub-classes of these exoplanets, "hot Jupiters" and their less massive counterparts "hot Neptunes," provide a unique opportunity to study the extended atmospheres of planets outside of our solar system. We describe here the first far-ultraviolet transit study of a hot Neptune, specifically GJ ...The closer a planet is to the Sun, the hotter it is. However, Uranus is colder than Neptune, even though it is further from the Sun. Astronomers believe that this is because Uranus' atmosphere is chaotic and its orientation is anomalous. Why should a planet situated a billion miles closer to the Sun than another planet be colder than it?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 ...

The paper is "An unlikely survivor: a low-density hot Neptune orbiting a red giant star." The lead author is Samuel Grunblatt from the Department of Physics and Astronomy at Johns Hopkins University. This hot Neptune is so close to its star that it completes an orbit in only 4.2 days. The planet, named TIC 365102760 b, is not very dense.

(Our Neptune has a mass and radius of 17.1 and 3.9 times the corresponding quantities for Earth, respectively.) The 'Neptune Desert' appears as a sterile region in the planetary mass-radius plane. Worlds like Neptune orbiting very close to their stars are rare indeed.

These planets suggest that the hot Neptune desert may be divided in two parts for planets with equilibrium temperatures of ≳1800 K: a hot sub-Neptune desert devoid of planets with radii of ≈ 1.8−3 R ⊕ and a sub-Jovian desert for radii of ≈5−12 R ⊕. More planets in this parameter space are needed to further investigate this finding.These planets suggest that the hot Neptune desert may be divided in two parts for planets with equilibrium temperatures of ≳1800 K: a hot sub-Neptune desert devoid of planets with radii of ≈ 1.8−3 R ⊕ and a sub-Jovian desert for radii of ≈5−12 R ⊕.

Neptune has a chilly atmosphere, with an average temperature of minus 200 degrees Celsius (minus 392 degrees Fahrenheit). …Like the other hot Neptune, this one's atmosphere appears negligible. Nevertheless, it might not have a rocky surface — it might be a "water world." "The core of the planet is rocky, but there could be a huge layer of water on top of the core, partially in supercritical form," Naponiello says.Neptune is actually pretty hot in the interior, about 7000 C, as hot as the surface of the sun. The only place actually cold is the cloud tops. As you descend the temperature goes up and at some ...

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.

Sizes to scale. The Earth Similarity Index ( ESI) is a proposed characterization of how similar a planetary-mass object or natural satellite is to Earth. It was designed to be a scale from zero to one, with Earth having a value of one; this is meant to simplify planet comparisons from large databases. The scale has no quantitative meaning for ...
