PDS 70 está aproximadamente a 370 años luz de distancia y presenta una gran brecha en su anillo interno. El telescopio muy grande del Observatorio Sur europeo proporcionó la primera imagen clara de un planeta que se formaba alrededor de la Estrella Central en 2018. El planeta es un punto brillante a la derecha del centro de la imagen. La Estrella Central es negra ya que su luz fue bloqueada por un instrumento conocido como coronagrafo. También se ha detectado un segundo planeta. Este sistema es un objetivo futuro del telescopio espacial James Webb de la NASA.

|---|---|
| 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. |
