En esta versión de la imagen de la cámara de infrarrojo cercano (NIRCAM) de Webb de Neptuno, las lunas visibles del planeta están etiquetadas. Neptuno tiene 14 satélites conocidos, y siete de ellos son visibles en esta imagen.
Triton, el punto brillante de la luz en la parte superior izquierda de esta imagen, eclipsa con creces a Neptuno porque la atmósfera del planeta se oscurece por la absorción de metano a longitudes de onda capturadas por webb. Triton refleja un promedio del 70 por ciento de la luz solar que la golpea. Se sospecha que Triton, que orbita a Neptuno en una órbita hacia atrás.

| About The Object | |
|---|---|
| Object Name | Neptune |

| Distance | Neptune's average distance from Earth is 2.7 billion miles |
| About The Data | |
| Data Description | This image was created from JWST data from proposal: (K. Pontoppidan). |
| Instrument | NIRCam |
| Exposure Dates | 12 July 2022 |
| Filters | F140M, F210M, F300M, F460M |
| About The Image | |
| Color Info | These images are a composite of separate exposures acquired by the James Webb Space Telescope using the NIRCam instrument. Several filters were used to sample different infraraed wavelength ranges. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are: Red: F460M Orange: F300M Green: F210M Blue: F140M |
| 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. |
