Ilustración de cómo podría ser Exoplanet Toi-421 B. To-421 B es un exoplaneta de tamaño subneptún que orbita una estrella del sol aproximadamente 244 años luz de la Tierra. Se cree que To-421 B tiene una atmósfera clara libre de neblina y nubes.
Esta ilustración se basa en nuestro conocimiento del planeta y su estrella anfitriona, y predicciones sobre las propiedades probables de la atmósfera del planeta. Los datos espectroscópicos de Webb nos ayudarán a comprender mejor la composición de la atmósfera del planeta.
toi-421 b está entre la tierra y la neptuno en términos de tamaño (radio 2.68 veces tierra), masa (7.2 veces tierra) y densidad (2 veces agua). Orbita su estrella a una distancia de solo 0.056 unidad astronómica (5.6% de la distancia entre la Tierra y el Sol), completando una órbita en 5.2 Días de la Tierra. La estrella, Toi-421, tiene un radio de 0.87 veces que el del sol, una masa 0.85 veces el sol y una temperatura de 5325 Kelvins (alrededor de 5050 grados centígrados), ligeramente más fresco que el Sol.

| 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. |
