Горячий нептун

Планета Глизе 436 b, горячий нептун в представлении художника.

Горя́чий непту́н — класс экзопланет, к которому относятся планеты с массой около массы Урана или Нептуна, которые расположены близко к своей звезде (всегда на расстоянии меньше 1 а.е.)[1]. Масса горячего нептуна состоит из ядра и окружающей плотной атмосферы, которая занимает большую часть размера планеты.

Недавние исследования показали, что популяция этого класса экзопланет может быть весьма велика[2].

В 2014 году открыто почти 2000 экзопланет, из которых большая часть является «горячими нептунами» и суперземлями[3].

История

Первыми известными горячими нептунами являются Глизе 436 b и мю Жертвенника c, которые были открыты в 2004 году[4][5].
