Why is 3C 273 so bright?
Why is 3C 273 so bright?
The light from 3C 273 is likely a combination of radiation from the accretion disk and from the bright jet. In many cases, we see jets from quasars and other AGN manifested as bright, extended radio galaxies, with fluffy lobes of radio emission billowing out to either side of the central engine.
Can you see 3C 273 with the naked eye?
Since it lies so close to the celestial equator, 3C 273 is equally visible from both the Northern and Southern Hemisphere.
What are the mass of and distance to 3C 273?
The mass of its central black hole has been measured to be 886 ± 187 million solar masses through broad emission-line reverberation mapping….
| 3C 273 | |
|---|---|
| Redshift | 0.158339 ± 0.000067 |
| Distance | 2.443 Gly (749 Mpc) (luminosity distance) |
| Type | Blazar; Sy1 |

How bright is 3C 273?
In other words, 3C273 was moving away from us at an incredible one-tenth the speed of light. 3C273 is the brightest quasar known, about 5 trillion times as bright as the sun. Quasars are the most distant objects visible, and 3C273 is no exception at 3 billion light-years away.
How big is 3C 273 compared to the Sun?
3C 273. Since the sun’s absolute magnitude is 4.83, it means that the quasar is over 4 trillion times more luminous than the Sun at visible wavelengths. The mass of its central black hole has been measured to be 886 ± 187 million solar masses through broad emission-line reverberation mapping.
What is the redshift of 3C 273 in light years?
They measured the redshift — the shift in wavelength of the observed spectrum caused by the expansion of the universe — and found 3C 273 had a staggering redshift of 0.158, placing it nearly two billion light years distant. But more exciting news was still to come.
What kind of star is 3C 273 Quasar?
3C 273 is a Quasar type star. 3C 273 is a Q quasar based on the spectral type that was recorded in the Hipparcos star catalogue. 3C 273 is not part of the Virgo constellation outline but is within the borders of the constellation.
What is the apparent magnitude of 3C 273?
The figure is derived at by using the formula from SDSS rather than peer reviewed papers. It has been known to produce widely incorrect figures. 3C 273 has an apparent magnitude of 12.88 which is how bright we see the star from Earth. Apparent Magnitude is also known as Visual Magnitude.
