2024年10月24日 · KELT-11 b is a gas giant exoplanet that orbits a G-type star. Its mass is 0.171 Jupiters, it takes 4.7 days to complete one orbit of its star, and is 0.06229 AU from its star. Its discovery was announced in 2017.

KELT-11b is an exoplanet orbiting around the yellow subgiant star KELT-11 (HD 93396) about 320 light-years away from Earth. It is an inflated planet, one of the "puffiest planets" (lowest-density) known, as a result of its close orbiting distance with its parent star.

kelt-11b是一颗环绕黄色次巨星kelt-11的太阳系外行星，距离地球约320光年。 该行星是其中一颗体积巨大的“蓬松行星”，其半径为 木星 的1.37倍，但质量只有地球的19% 。

2017年4月18日 · We report the discovery of a transiting exoplanet, KELT-11b, orbiting the bright (V = 8.0) subgiant HD 93396. A global analysis of the system shows that the host star is an evolved subgiant star with K, , , , and .

2017年5月16日 · KELT-11b is an extreme version of a gas planet, like Solar System’s Jupiter or Saturn, but is orbiting very close to its host star in an orbit that lasts less than 5 days. “This planet is highly inflated, so that while it’s only a fifth as massive as Jupiter, it is nearly 40% larger, making it about as dense as styrofoam,” said Dr ...

2016年7月6日 · We report the discovery of a transiting exoplanet, KELT-11b, orbiting the bright () subgiant HD 93396. A global analysis of the system shows that the host star is an evolved subgiant star with K, , , log , and [Fe/H].

2022年9月1日 · The characteristics of KELT-11 b, notably its extreme scale height and long transit, make it an ideal and unique target for next-generation telescopes. Our results as well as recent findings from HST, TESS, and CHEOPS observations could make KELT-11 b a benchmark exoplanet in atmospheric characterization.

We report the discovery of a transiting exoplanet, KELT-11b, orbiting the bright (V = 8.0) subgiant HD 93396.

This page summarises the information held within TEPCat for the transiting planetary system KELT-11. Please see here for descriptions of the quantities given below. Discovery and basic observable quantities:

KELT-11 is the brightest known transiting exoplanet host in the southern hemisphere by more than a magnitude and is the sixth brightest transit host to date. The planet is one of the most inflated planets known, with an exceptionally large atmospheric scale height (2763km), and an associated size of the expected atmospheric
