It appears in this image as just a small dim star like object. It's measured redshift of 0.158339 places it at a current distance of 2.124 billion ly moving away from us at 15.3% of the speed of light. It was 1.834 billion ly away when the light in this image started its journey taking 1.973 billion years to reach us.  It's the first quasar ever detected. It's also the brightest quasar in our sky and is, at an absolute magnitude of -26.7, one of the brightest objects we've ever detected. If it were only 30 ly away it would be as bright as the Sun even though this is 7 times farther away than our neighboring star Alpha Centauri.
