望远镜观测通常仅仅能提供关于某颗系外行星的基本信息，诸如最小质量、与母恒星的距离、以及是否更可能是气态的或者像地球那样是岩石质的。
Telescopic surveys usually reveal just basic information about an extrasolar planet's minimum mass, its distance from its parent star, and whether it is likely to be gassy or rocky, like Earth.
它是唯一的一颗已知的“超级地球”外行星-质量在地球与海王星之间-被证实了有大气。
It is the only known "Super-Earth" exoplanet-worlds that have masses between Earth and Neptune-with a confirmed atmosphere.
它的母恒星与太阳相似，这又与其他两个候选外行星不同，其他两个候选外行星都环绕较冷的、较昏暗的恒星运行。
Its parent star is similar to the sun, again unlike those of the other two candidates, both of which orbit cooler, dimmer stars.
