But do the ice molecules vibrate faster than the ones on Earth? Alien Planet Covered in Hot Ice. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit this simple FaQ for additional information. In the news, Gliese-436b gained great attention because it was said to be made out of "burning ice." ... And the density of GJ 436b suggests it is made of water. Gliese 436b is a Neptune sized world orbiting an orange-red dwarf about 30 light years away. GJ 436b is a Jovian planet orbiting the Gliese 436, it was the first Hot Neptune discovered by Earth, at the end being detected up to its clouds.One of its main characteristics, even at such a high temperature, more than 400 degrees, it still has ice, obviously not being an ordinary ice, but formed by compressed water at a very high pressure. ... with balmy temperatures and orbiting a red dwarf star called Gliese 581. The star-hugging, extremely hot exoplanets discovered so far seem to fall into two opposite groups. I understand that the ice on Gliese 436 b is in solid form because of its high pressure. It was among the smallest knowntransiting planets in mass and radius until the much smaller Kepler discoveries started coming in 2010. TROPHY CASE. It is demonstrated that Gliese 436b should have an extended wind interactions with the radiatively braked exosphere of GJ 436 b⦠Verified Email. 2 Answers. This is In 2004, the existence of an extrasolar planet, Gliese 436b, was verified as orbiting the star. Gliese 436 b is speculated to have an ocean of " hot ice ". The ultraviolet transits repeatedly start ~2 h before, and end >3 h after the ~1 h optical transit, which is substantially different from one previous claim (based on an inaccurate ephemeris). 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. 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. Itâs a Neptune-sized planet that orbits a red-dwarf star (Gliese 436) approximately 33.1 light-years away in the zodiac constellation of Leo. Despite surface temperatures that can reach 800 degrees Fahrenheit, the world is still covered in ice.
