PDS 70
A young K star with a broad disk gap and two directly imaged giant planets still forming inside it.
Also known as V1032 Centauri.
Catalog
Position basis, the same label the app shows on the selection card.
Every aspect, with its origin
One record per aspect. The origin says what kind of thing each value is; the source says where it came from; the limit says what it cannot tell you.

Confirmed planets PDS 70 b and c
Planet markers use the semi-major axes and periods in the NASA Exoplanet Archive; their displayed orbital phase is normalized because a complete visual-orbit solution is not available here.

LimitMarker phase is a presentation phase, not an astrometric prediction.
ALMA Band 7 observation
The ALMA observation of the circumstellar ring and emission associated with the planets’ region is available under Evidence & sources.

Disk rendering
The close-up wraps the ALMA Band 7 image (855 μm) on a disk tilted to the published inclination and position angle, with 36,000 particles sampled from its ring profile.
LimitVertical structure and the far side of the disk are not resolved by the image; scale height is a display choice.
