Шаблон:Short description Шаблон:Infobox planet HIP 116454 b, or K2-2 b,[1] is an exoplanet orbiting the star HIP 116454, Шаблон:Convert from Earth toward the constellation Pisces. It is Шаблон:Convert in diameter and 12 times as massive as Earth.[2][3] It was discovered by the NASA Kepler spacecraft, and is the first exoplanet discovered during KeplerШаблон:'s K2 mission.[4] The discovery was announced on December 18, 2014. Шаблон:Nowrap does not have a normal Kepler designation due to not being located in the original Kepler field.[4]

Шаблон:Nowrap was discovered in a Kepler engineering data set which was collected in preparation of the first full K2 campaign. Unlike most other Kepler planets, only a single transit event of Шаблон:Nowrap was detected, requiring follow-up radial velocity measurements by the HARPS-N spectrograph and photometric measurements by the Canadian MOST satellite.[5][6]

Physical characteristics of Шаблон:Nowrap are expected to be similar to Kepler-68b, being somewhere between super-Earth and mini-Neptune.[5]
