El concepto de este artista muestra cómo podría verse el Wasp-17 B Exoplanet.
Wasp-17 B, también llamado Ditsö̀, es un gigante de gas caliente que orbita su estrella a una distancia de solo 0.051 Au (aproximadamente 4.75 millones de millas, o un ocho la distancia entre Mercury y Sun), completando un circuito completo en aproximadamente 3,7 días de tierra. El sistema se encuentra dentro de la Vía Láctea, aproximadamente 1.300 años luz de la Tierra, en la constelación de Scorpius.
con un volumen más de siete veces mayor que el de Júpiter y una masa menos de la mitad de Júpiter, Wasp-17 B es un planeta extremadamente hinchado. Su corto período orbital, gran tamaño y una atmósfera gruesa y extendida lo hacen ideal para la observación utilizando spectroscopy de transmisión , que implica midear los efectos del planeta en el filtro de la estrella de la estrella estrella. La atmósfera de
WASP-17 B está compuesta principalmente de hidrógeno y helio, junto con pequeñas cantidades de vapor de agua y toques de dióxido de carbono y otras moléculas. Las observaciones de 5- a 12-micron infrare de luz de Webb's miió de nanocristales de cuarzo (SIO 2 ).
WASP-17 B se bloquea tidialmente y tiene una órbita retrógrada. Its temperature ranges from about 1,000 kelvins (1,350 degrees F or 725 degrees C) on the cooler nightside to nearly 2,000 kelvins (3,150 degrees F or 1,725 degrees C) on the side in permanent daylight.
The star, WASP-17 (also called Diwö), is an F-type star: slightly larger, more massive, más caliente y más blanco 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. |
| About The Data | |
| Data Description |
|
| Instrument | The science instrument used to produce the data. |
| Exposure Dates | The date(s) that the telescope made its observations and the total exposure time. |
| Filters | The camera filters that were used in the science observations. |
| About The Image | |
| Image Credit | The primary individuals and institutions responsible for the content. |
| Publication Date | The date and time the release content became public. |
| Color Info | A brief description of the methods used to convert telescope data into the color image being presented. |
