Hubble has now spotted a hot Neptune named GJ 3470b that's vanishing at a record rate. However, it can be viewed with even a modest telescope of 2.4 in (6 cm) aperture. 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 sigma), far beyond the 0.69% optical transit depth.

Gliese 436 b is a Neptune-sized extrasolar planet orbiting the red dwarf star Gliese 436. Gliese 436b is a Neptune sized world orbiting an orange-red dwarf about 30 light years away. Nel 2007 è stato osservato un transito del pianeta sulla propria stella. ... And the density of GJ 436b suggests it is made of water. [8] It was the first hot Neptune discovered with certainty (in 2007) and was among the smallest known transiting planets in mass and radius, until the much smaller Kepler exoplanet discoveries started coming in by 2010. ... An artist's conception shows the Neptune-size planet GJ 436b, or Gliese 436b, orbiting a cool, red star just 30 light-years from Earth. Gliese_436b 0 points 1 point 2 points 26 days ago Discovary : Gliese 436 b was discovered in August 2004 by R. Paul Butler and Geoffrey Marcy of the Carnegie Institute of Washington and University of California, … Discovery. The temperature of this planet is 712 K (439 degrees C) which indicates that this planet is very close to its star. In the case of GJ 436b, the distance is such that its orbital period is just over 2.5 Earth’s days. Gliese 436 b was discovered in August 2004 by R. Paul Butler and Geoffrey Marcy of the Carnegie Institute of Washington and University of California, Berkeley, respectively, using the radial velocity method.Together with 55 Cancri e, it was then the first of a new class of planets with a minimum mass (M sini) similar to Neptune. Strange alien world made of hot ice New Scientist. I have just modified one external link on Gliese 436 b. HAT-P-11b is quite similar in mass and radius to Gliese 436b, and it’s actually somewhat larger than Neptune on both counts. It is demonstrated that Gliese 436b should have an extended wind interactions with the radiatively braked exosphere of GJ 436 b… Please take a moment to review my edit. Gliese 436b has flabbergasted scientists since it was first discovered in 2004. Astronomy: Does the ice on Gliese 436 b have higher kinetic energy than the ice on Earth because it has a higher temperature? This is a reference to the possible ice beneath it's atmosphere, compressed into solid form by gravity and pressure. Gliese 436 is a red dwarf approximately 31.8 light-years (9.7 parsecs) away in the zodiac constellation of Leo.It has an apparent visual magnitude of 10.67, which is much too faint to be seen with the naked eye. It's extremely close to its sun and very hot. what's this? The star-hugging, extremely hot exoplanets discovered so far seem to fall into two opposite groups. The planet is about 4000 km larger in diameter than Uranus and 5000 km larger than Neptune and a bit more massive.

Gliese 436 b /ˈɡliːzə/ (sometimes called GJ 436 b[7]) is a Neptune-sized exoplanet orbiting the red dwarf Gliese 436. The high temperatures and pressures would form exotic materials like'hot ice'or'superfluid water '. This high temperature indicates that water in any […] Relevance. Gliese-436b also gained interest after astronomers found the planet losing its atmosphere in a trail. GJ 436b, "Hot Ice" Planet Discovered, Covered in "Solid Water," Experts Say John Roach for National Geographic News May 17, 2007. But do the ice molecules vibrate faster than the ones on Earth? Gliese 436 b è stato scoperto nel 2004, ed è uno dei primi pianeti delle dimensioni di Nettuno individuati al di fuori del nostro sistema solare. One-Year Club. Together with 55 Cancri e, it was then the first of a new class of planets with a minimum mass (M sini) similar to Neptune. It has been determined that the world is made mostly of water so the high temperatures would make the atmosphere mostly steam but the higher pressures further down would compress the water into a super heated but solid state called "hot ice".
