A neutron star is so dense that one teaspoon (5 milliliters) of its material would have a mass over 5.5 × 10 12 kg, about 900 times the mass of the Great Pyramid of Giza. [b] The entire mass of the Earth at neutron star density would fit into a sphere 305 m in diameter, about the size of the Arecibo Telescope.
For a typical neutron star of 1.4 solar masses (M ☉) and 12 km radius, the nuclear pasta layer in the crust can be about 100 m thick and have a mass of about 0.01 M ☉. In terms of mass, this is a significant portion of the crust of a neutron star. [9] [10]
PSR J0952–0607 is a massive millisecond pulsar in a binary system, located between 3,200–5,700 light-years (970–1,740 pc) from Earth in the constellation Sextans. [6] It holds the record for being the most massive neutron star known as of 2022, with a mass 2.35 ± 0.17 times that of the Sun—potentially close to the Tolman–Oppenheimer–Volkoff mass upper limit for neutron stars.
Densities are in terms of ρ 0 the saturation nuclear matter density, where nucleons begin to touch. Patterned after Haensel et al. , [ 7 ] page 12 Some authors use "nuclear matter" in a broader sense, and refer to the model described above as "infinite nuclear matter", [ 1 ] and consider it as a "toy model", a testing ground for analytical ...
In astronomy, Calvera (also known as 1RXS J141256.0+792204 [4]) is an X-ray source in the constellation Ursa Minor, identified in 2007 as an isolated neutron star. [5] [6] It is one of the hottest [7] and closest of its kind to Earth.
Like other neutron stars, magnetars are around 20 kilometres (12 mi) in diameter, and have a mass of about 1.4 solar masses. They are formed by the collapse of a star with a mass 10–25 times that of the Sun. The density of the interior of a magnetar is such that a tablespoon of its substance would have a mass of over 100 million tons. [2]

The first radio pulsar was discovered in 1967 by Jocelyn Bell and her adviser, Antony Hewish using the Interplanetary Scintillation Array. [4] Franco Pacini and Thomas Gold quickly put forth the idea that pulsars are highly magnetized rotating neutron stars, which form as a result of a supernova at the end of the life of stars more massive than about 10 times the mass of the Sun (M ☉).
