The fact that "one represents only known facts" hardly matters, nobody will be perfectionist at this point. Also in PC both images appear at the same time, so disputing for which image should be in infobox is pointless.Tags: Mobile edit Mobile web edit Advanced mobile edit← Previous edit |

It has been called "one of the most important planets ever discovered beyond the Solar System": Due to its relative proximity to Earth, telescopes should be able to determine the composition of its atmosphere, the speed of its winds and the color of its sunsets. This is due in part to the small diameter of its parent star (20% that of the Sun), which increases the effect on the star's light of its transits. The planet's diameter is approximately 20% larger than that of the Earth and its mass is estimated at 1.6 times that of Earth, implying that it has an Earth-like rocky composition. GJ 1132 b orbits its star every 1.6 days at a distance of 1.4 million miles (2.24 million kilometres).
In April 2017, a hydrogen-dominated atmosphere was claimed to have been detected around GJ 1132 b. However, subsequent, more precise work ruled out the claim. Instead, in 2021 detection of a hazy hydrogen atmosphere without helium but with the admixture methane and hydrogen cyanide (implying substantial underlying free nitrogen in the mix, at around 8.9% of the atmosphere) was claimed. However, two subsequent studies found no evidence for molecular absorption in the HST WFC3 Spectrum of GJ 1132 b. Instead, the spectrum was found to be flat, which is more consistent with our current understanding of photoevaporation.
