K2-3, also known as EPIC 201367065, is a red dwarf with three known planets. All are Super-Earths, and the outermost is in the habitable zone. It is on the borderline of being a late orange dwarf/K-type star, but because of its temperature, it is classified as a red dwarf (4,000 K is typically the division line between spectral class M and K). At a distance of about 144 light-years, the star's proximity means it is bright enough to make it feasible for astronomers to study the planets' atmospheres to determine whether they are like Earth's atmosphere and possibly conducive to life.

  • K2-3 è una stella nana rossa nella costellazione del Leone, distante circa 144 anni luce dal sistema solare. Nel 2015, nell'ambito della missione estesa del telescopio spaziale Kepler, è stato scoperto attorno a essa un sistema planetario composto da almeno tre esopianeti, uno dei quali orbitante nella zona abitabile della stella, dove potrebbero esserci condizioni propizie per l'esistenza di acqua liquida sulla sua superficie.

  • K2-3, também conhecida como EPIC 201367065, é uma estrela anã vermelha localizada a cerca de 137 anos-luz (45 pc de distância a partir da Terra, na constelação Leo. Esta estrela possui três planetas conhecidos. Todos são superterras, e a mais externa está na zona habitável de K2-3. A estrela de baixa massa é brilhante nas proximidades, o que torna este sistema um excelente laboratório para determinar as massas dos exoplanetas através de espectroscopia Doppler e para determinar suas composições atmosféricas através de espectroscopia de trânsito.

  • K2-3 – gwiazda położona w gwiazdozbiorze Lwa w odległości około 150 lat świetlnych. Jest czerwonym karłem z trzema znanymi planetami, klasyfikowanymi jako superziemie, z których najbardziej zewnętrzna znajduje się w ekosferze. Wielkość gwiazdowa K2-3 wynosi 12m. (pl)
  • K2-3 — красный карлик в созвездии Льва на расстоянии 44 пк с тремя известными экзопланетами. Планетная система звезды была открыта фотометрическими наблюдениями КТ «Кеплер» в 2015 году. На 2019 год K2-3 входит в десятку ближайших звёзд, о которых известно, что они имеют транзитные планеты. Благодаря её близкому расположению, она достаточно яркая для изучения газового состава их атмосфер. (ru)
  • K2-3( 也稱為EPIC 201367065)是一顆位於獅子座的紅矮星,目前已知有三顆行星繞行。這三顆行星都是超級地球,位於可居住區最外層。K2-3的性質類似橙矮星/K型星,科學家根據其表面溫度(4,000K是M和K型星典型光譜分界線)分類為紅矮星。 K2-3距離地球137光年,是最近10顆擁有凌日行星的恆星之一。天文學家可以研究其行星大氣層,確定它們是否類似地球大氣層,有利於生命存在。 (zh)
