The exoplanet is known to astronomers GJb, or Gliese b. Paul; et al. Finally, the astronomers say, observations like this one might help us to picture the distant future of our planet, when, in 3 or 4 billion years, our sun swells to become a red giant. The inward migration caused by this interaction could have triggered the atmospheric escape that sustains its giant exosphere. Whatever energy tidal effects deliver to the planet, it does not affect its temperature significantly.
Gliese b /ˈɡliːzə is a Neptune-sized exoplanet orbiting the red dwarf Gliese It was Gliese b orbits at a distance of four million kilometers or one-fifteenth the average distance of Mercury from the Sun. The planet's surface temperature is estimated from measurements taken as it passes behind the star to be.
This is Gliese b, a planet just 30 light-years away. which is composed mostly of hydrogen gas and has such high surface temperatures. Concept Art of Gliese b and its parent star, Gliese – NASA However, the ice on the surface of Gliese b is not normal ice.
Gliese b was discovered in August by R.
A study published in Nature found that the orbit of Gliese b is nearly perpendicular to the stellar equator of Gliese and suggests that the eccentricity and misalignment of the orbit could have resulted from interactions with a yet undetected companion.

However, when the radius became better known, ice alone was not enough to account for it. Tweets by earthskyscience.
As it arrived in range, the star would have blown off the planet's hydrogen layer via coronal mass ejection. What is the Ring of Fire? Astrophysicists now hypothesize that our planet would be transformed into a giant comet, thus resembling a comet, much like GJb. InUSA Today reported that the exoplanet's burning ice continued to have scientists "flabbergasted.
