Neutron star · ~2.08 M☉
PSR J0740+6620
One of the most massive neutron stars known, at about 2.08 solar masses, weighed through the Shapiro delay of its pulses. Its radius has been measured by NASA's NICER X-ray telescope, and together the mass and radius are among the tightest constraints on the neutron-star equation of state and how dense matter behaves.
