K2-66b

K2-66b is a confirmed[2][3][failed verification] mega-Earth orbiting the subgiant K2-66, about 520 parsecs (1,700 ly) from Earth in the direction of Aquarius.

[1] It is an extremely hot and dense planet heavier than Neptune, but with only about half its radius.

[5] The planet's temperature is highly variable due to the variability of its host star, and is currently estimated at 1,372 K (1,099 °C; 2,010 °F).

[2] The planet orbits every 5.07 days at 0.06 AU.

[5] It has a sun-like temperature of 5887 K,[1][2] which corresponds to its spectral class and is very close to that of the rotationally variable[9] star Kepler-130.
