系外行星特性探測衛星
Sign in to saveAlso known as Characterising Exoplanets Satellite
CHEOPS (CHaracterising ExOPlanets Satellite) is a European space telescope. Its objective is to determine the size of known extrasolar planets, which will allow the estimation of their mass, density, composition and their formation. Launched on 18 December 2019, it is the first Small-class mission in ESA's Cosmic Vision science programme. The small satellite features an optical Ritchey–Chrétien telescope with an aperture of 30 cm, mounted on a standard small satellite platform. It was placed into a Sun-synchronous orbit of about 700 km altitude.

系外行星特性探測衛星（CHaracterising ExOPlanets Satellite）是歐洲太空總署一台太空望遠鏡，目的是研究太陽系外行星形成。 系外行星特性探測衛星在2019年12月18日發射升空，任務目的是讓一座安裝在標準衛星平台上的里奇-克萊琴望遠鏡進入太陽同步軌道（約800公里）。在3.5年執行任務時間，系外行星特性探測衛星將檢測地球附近已知的太陽系外行星。
