Exoplanet rocoso Trappist-1 B (ilustración)

Esta ilustración muestra cómo podría verse el Hot Rocky Exoplanet Trappist-1 B en base a este trabajo. Trappist-1 B, el más interno de siete planetas conocidos en el sistema Trappist-1, orbita su estrella a una distancia de 0.011 Au, completando un circuito en solo 1.51 días de tierra. Trappist-1 B es ligeramente más grande que la Tierra, pero tiene alrededor de la misma densidad, lo que indica que debe tener una composición rocosa. La medición de Webb de la luz del infrarrojo medio emitido por Trappist-1 B sugiere que el planeta no tiene ninguna atmósfera sustancial. La estrella, Trappist-1, es un enano rojo Ultracool (enano M) con una temperatura de solo 2,566 kelvins y una masa solo 0.09 veces la masa del sol. 

Esta ilustración se basa en nuevos datos recopilados por el instrumento de infrarrojo medio de Webb (MIRI), así como Observaciones anteriores de otras telescopes basadas en el suelo y espaciales. Webb no ha capturado ninguna imagen del planeta.

About The Object
Object Name A name or catalog number that astronomers use to identify an astronomical object.
Object Description The type of astronomical object.
R.A. Position Right ascension – analogous to longitude – is one component of an object's position.
Dec. Position Declination – analogous to latitude – is one component of an object's position.
Constellation One of 88 recognized regions of the celestial sphere in which the object appears.
Distance The physical distance from Earth to the astronomical object. Distances within our solar system are usually measured in Astronomical Units (AU). Distances between stars are usually measured in light-years. Interstellar distances can also be measured in parsecs.
Dimensions The physical size of the object or the apparent angle it subtends on the sky.
