PSO J352-15
LENSED · SCHWARZSCHILD FROM ACCRETION QUASAR · INCLINATION NOT MEASURED
OVERVIEW
] BLACK HOLEPSO J352-15 is a in the constellation Aquarius, 179.4 from Earth. It was discovered in 2018.
A radio-loud quasar in the early universe, and one of very few from that era whose jets have been resolved: two lobes about 1,600 light-years apart, imaged across a distance that leaves them a few thousandths of an arcsecond across.
- WHAT IT IS
- Quasar
- HOW FAR
- 179.4
A luminosity distance, from its redshift — how faint it looks. The light itself left 12.4 billion years ago.
OBSERVING
] FROM WHERE YOU AREWhat it takes to see PSO J352-15 for yourself. Everything in this part of the page is worked out for a real horizon, a real night and the equipment you say you have.
Say where you are, and this line says when PSO J352-15 is worth going out for.
APPARENT PLACE
] EQUINOX J2026.7Where a telescope has to be pointed today, which is not quite where the catalogue records the object: the coordinate grid itself has turned since the year 2000 the catalogue is referred to.

- PROPER MOTION SINCE
- none published
Computed for 2026-09-03 00:00 UT. No proper motion is published for PSO J352-15, so nothing here moves the object; what separates this from the catalogued position above is the coordinate grid turning under it — about fifty arcseconds a year of precession since 2000, and the small nodding of the Earth’s axis on top of that. Aberration and refraction are not included, and neither is parallax; each is under an arcminute, which is also about as well as the catalogued position is known. The same figure for any date.
CATALOG DATA
] 2 FIELDSThe raw catalogue values, as the source published them, with the error bars where one was published — sorted by what each set of figures is about rather than by the order they happened to be stored in.
WHAT KIND OF THING IT IS
What the object is in itself, rather than how it happens to look from here.
- Accretion state
- quasar — a thin disc near its Eddington limit
WHERE IT IS AND HOW IT MOVES
Position, motion across the sky and the size it covers on it. These are measurements of the object as seen from here, so every one of them depends on where here is.
