Este concepto de artista representa el Rocky Exoplanet GJ 486 B, que orbita una estrella enana roja que está a solo 26 años de luz en la constelación de Virgo. Al observar el transit GJ 486 B frente a su estrella, los astrónomos buscaron signos de una atmósfera. Detectaron toques de vapor de agua. Sin embargo, advierten que si bien esto podría ser un signo de una atmósfera planetaria, el agua podría estar en la estrella misma, específicamente, en los puntos de estrella fríos, y no del planeta.
GJ 486 B es aproximadamente un 30% más grande que la Tierra y pesa tres veces más. Orbita su estrella de cerca en poco menos de 1.5 días.

| 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. |
