UM 287 (also PHL 868 or LBQS 0049 + 0045) is a quasar in the constellation whale with a cosmological redshift of z ≈ 2.3. It was discovered between 1974 and 1976 as part of the Curtis Schmidt-thin prism survey for extragalactic emission-line objects at the University of Michigan . Its bolometric brightness is estimated at 10 ^47.3 erg / s, the emitted light took about 10 billion years to reach the earth.
