Summary
| Description |
English: This artist's concept appeared on the Feb. 23, 2017 cover of the journal Nature announcing that the TRAPPIST-1 star, an ultra-cool dwarf, has seven Earth-size planets orbiting it. Any of these planets could have liquid water on them. Planets that are farther from the star are more likely to have significant amounts of ice, especially on the side that faces away from the star.
The system has been revealed through observations from NASA's Spitzer Space Telescope and the ground-based TRAPPIST (TRAnsiting Planets and PlanetesImals Small Telescope) telescope, as well as other ground-based observatories. The system was named for the TRAPPIST telescope. NASA's Jet Propulsion Laboratory, Pasadena, California, manages the Spitzer Space Telescope mission for NASA's Science Mission Directorate, Washington. Science operations are conducted at the Spitzer Science Center at Caltech, also in Pasadena. Spacecraft operations are based at Lockheed Martin Space Systems Company, Littleton, Colorado. Data are archived at the Infrared Science Archive housed at Caltech/IPAC. Caltech manages JPL for NASA.

Cualquiera de estas planetas podría contener agua en estado liquido. Las planetas que son más lejos de la estrella son mas propensos a tener una cantidad considerable de hielo, particularmente en la cara que está orientada lejos de la estrella.
El sistema se ha revelado por observaciones de Telescopio espacial Spitzer de NASA y el telescopio terrestre TRAPPIST (Telescopio Pequeño para Planetas y Planetesimales en Tránsito), así como otros observatorios terrestres. El sistema fue llamado así por el telescopio TRAPPIST. El Laboratorio de Propulsión a Reacción (JPL) de NASA en Pasadena, California, dirige la misión para la Science Mission Directorate de NASA, en Washington. Se realizan las operaciones científicas en el Centro Científico Spitzer en el Instituto de Tecnología de California (Caltech), también en Pasadena. Las operaciones de nave espacial están basadas en Lockheed Martin Space Systems Company, Littleton, Colorado. Los datos son archivados en el Archivo de Ciencia Infrarroja en Caltech y IPAC. Caltech dirige JPL para NASA. Para más información acerca a la misión Spitzer, véase http://www.nasa.gov/spitzer y http://spitzer.caltech.edu (Inglés). |
