Exoplanets PDS 70 b and c
About This Image
Caption
PDS 70 is only the second multi-planet system to be directly imaged. Through a combination of adaptive optics and data processing, astronomers were able to cancel out the light from the central star (marked by a white star) to reveal two orbiting exoplanets. PDS 70 b (lower left) weighs 4 to 17 times as much as Jupiter while PDS 70 c (upper right) weighs 1 to 10 times as much as Jupiter.

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.
About The Data
- Data Description
- Proposal: A description of the observations, their scientific justification, and the links to the data available in the science archive.
- Science Team: The astronomers who planned the observations and analyzed the data. "PI" refers to the Principal Investigator.
